Fully understandable - don't get distracted at this point sounds like you are almost there with the bootloader. As you said think you are going to make a lot of folks happy when the bootloader becomes available.

#1 I think is along the same lines as was done in MTP in the storage class: uint32_t addFilesystem(FS &fs, const char *name) {return sd_addFilesystem(fs, name);} ........ uint32_t sd_addFilesystem(FS &fs,...

Well I started playing with the wavFilePlayer code but run into a problem how to handle pointing the to constructor for each type of FLASH (QSPI, SPI, FRAM) in the play_sd_xxx files in the audio library. Right how SD...

@Frank B Now that I know LittleFS works with LC I started looking at wavPlayer sketch. Think a few files are going to have modified especially play_sd_wav.cpp

Ok figured out the problem and its not LittleFS. Problem is just running out of memory within the sketch. There are a few array of 2048 and while by itself is not bad, add that with the sketch size probably causing an...

Another data point. Just ran my bench sketch for read/write and that seemed to work except totalSize is returning 0! LittleFS Test...

Not nice :(. That was with SerialFlash not LittleFS. LittleFS seems to be having a problem with LC.

MOrning @KurtE A bit. Hate leaving things hanging so I had to finish off the BBM stuff (not much more I can do on that) and test the LC I just remembered. Going to do a few more tests just in case

Teensy LC Issue with LittleFS @Frank B asked about if we did any testing with Teensy LC (https://forum.pjrc.com/threads/64592-Teensyduino-1-54-Beta-5?p=266527&viewfull=1#post266527) so I hooked up a LC to the...

Ok just pushed the last update to plusNAND as well @Paul 's LittleFS library. I added support for Bad Block Management (BBM) for the M02. As I said before its not turned on (didn't send the command). Reason: Not...

@PaulStoffregen - @defragster - @KurtE In regards to BBM on the W25N02 I contacted Winbond to see if it was an error in the datasheet for the N02. Well, I got back an answer today and basically its not supported: ...

Afternoon now for me. So afternoon. Oh man - frustrating when internet is down - been there. Ok saw where the case statement was missing. Added it in to MTP.cpp and that seems to resolve the issue with copying and...

Morning @KurtE - had my coffee now. T3.5 and T3.6 both build with no errors. But unless I missed something I can not copy any files to the flash (n01 in this case). However, I can copy from the flash to the...

Ok think I am lost on what changes need to be made to the core - think I am behind on some things. Is your core files updated and which branch can I use to be even the MTP changes. EDIT: Never Mind figure it out. ...

@WMXZ I have been using @KurtE's branch of MTP for testing so I left the 'd' in to test events - as a debug tool as you said.

At from me the answer is not to both - I do have a Teensy LC someplace but have to find what I did with it.

@defragster - @KurtE - @Paul Just did a few more tests using the MPT-logger sketch just as a sanity check and see if I got any ECC errors well everything worked. The below is a table of chips tested and whether they...

Very cool Frank - thanks for adding Hardfaults was a nice feature

Just out of curiosity did you try it the way T3.x does it - probably should run a test to see if it works. Stay tuned EDIT: You probably know this but getting usb event errors on compile for the T3.5"...

@defragster - @KurtE Pretty much what Kurt said - there is some sort of conflict but didn't spend much time tracking it down specifically as I just rewrote to get rid of I2S/DMA and use the MPU-9250 to get real data. ...

Just as a heads up and by way of explanation of the libraries: teensy41_extram - only used for direct writing to the PSRAM and is a bit out dated and really doesn't need to be used anymore. Do a search on EXTMEM there...

Ok - reworked the mtp-logger example to just read data from MPU-9250 and store it on any of our flash chips, now it works no problem with the NAND on QSPI. Must be that conflict @KurtE mentioned. If you want to play:...

Ok just wrote a simple test case that seems to be working - probably do better on next update but wanted to see if this was going to work and it did - so probably a conflict as you identified: Logger Device ID:...

Morning - all mornings seem to be the same lately. Yep - made sure of that. Right now I am in the process of putting together a basic logger using similar functions for creating files/directories and writing data....

@KurtE - @defragster Still puzzling me about the problem with using the MTP logger. Wondering if there is some sort of issue with using DMA and/or I2S with QSPI NAND Flash? But funny thing is that it does work with...

@KurtE Of course it would be nice to have a file creation or file modified date but as you said not sure how LittleFS supports that. I was reading that LFS has custom attributes that you can set and doing a search...

@defragster - @KurtE Decided to try to modify the MTP_logger example to work with the selected device for logging data. I tested SD, SPI, QSPI, and SPI NAND which all worked without an issue. However, when I tried...

@KurtE = @defragster Just pushed an update to plusNAND to bring LittleFS even with what I have updated for NAND. In the READ_BCC test case I added a quick test of the addbblut function - I think I got it working...

Good Morning @KurtE I finally got to download your latest updates and they seem to be working. If I hit F5 on the PC they do show up. The other commands seem to working as well I tried the 'd' command and that...

@KurtE Thanks Kurt for the info Kurt. Think the stuff for keep reading the data actually helped. If I remember right when I was using it I was able to transfer the 5Mb file. Maybe its worth putting back in at some...

Yep that's the latest. I did the push yesterday for the BBLUT stuff so not sure if you have those changes in your version.

@KurtE Ok I did what I described in post #591. It recognized the N01 and N02 chips on the memory breakout board was able to create a directory and copy files up to 1.1Mb and the was able open/delete them. However if...

Morning @KurtE See you have been busy again :) Anyway so if I am reading your post right I should go ahead update the core with your changes: https://github.com/PaulStoffregen/cores/pull/532 and then use your...

Took your advice and issued a PR (Updated for NAND/FeRAM.Fram and tweaks) for what we have so far.

That looks like my breakout board C that I tested successfully with the SPI. Just for reference I am using the Bolderflight library with the 200 ns delays which is the PR that was referenced. However, the standalone...

Just as a quick update I reconfigured BreakoutBoard D to use SPI1: #define PIN_MISO1 1 #define PIN_MOSI1 26 #define PIN_SCK1 27 #define PIN_CS1 10 or 0 Again...

Ok just got back to this. Unfortunately I deleted my original message before hitting save so this is just a summary. Tested with 4 different breakout boards: Breakout Board A: DOA both for I2C and SPI. Scanner...

Don't think the problem is with Teensy as @WMXZ stated. Believe there is a problem with SPI implementation with the library. As a quick and dirty test for SPI with the MPU-9250 I updated an old test library I had...

Just tried a couple things moved it over to SPI and used CS = 10. See failure to correctly who I am register - getting 112 instead of 113/115. There is already a delaynanoseconds(200) with beginTransactions. This...

Great - another data point. Just hooked up my DFRobot BMP388 to a Teensy 4.0 and its working without a problem. Just got it last night but was distracted with LittleFS again. EDIT: Think I put back the delay(40)...

@KurtE - @defragster -@PaulStoffregen Just pushed a change up to the repository for W25N01G NAND flash to support Bad Block Management. I brought it to the point of actually writing the Table. A little reluctant to...

As you probably noticed LadyAda requested a PR for them to evaluate so I just sent them a PR: https://github.com/adafruit/Adafruit_BMP3XX/pull/14. EDIT: Quick up the Adafruit Library has been updated.

@KurtE Totally a loss at this point. Something definitely odd going on. For my Flash QSPI tests I used a kludged setup where I solder wires from the Flash pad to a set of headers for the flash chip and it seems to...

First the W25Q16JV-DTR is a NOR Flash chip, yes I know that the datasheet is silent on it but if you do a searching you will find that Mouser and Winbond shows it as a NOR flash. Second if you don't include the...

@KurtE Ok - I am at a loss now especially since neither pass the teensy41_psram_memtest sketch. That should have worked. Out of curiosity did you ever give it a try with our old (very old teensy41_extram library...

Yeah - know the feeling. Glad its working for you.

Saw that as well. Got lost after that as I couldn't visualize how sm_malloc was interfacing with PSRAM/FLEXSPI commands for read/write? Just didn't see the linkage between the two

Cool glad thats all it was.

Just as a quick follow up to yesterday's post I just tested the sketch on the Uno, Due, Mega and a Teensy 3.5 with the delay(40) removed and it seemed to work with an issue.

First you are not crazy. Received my BMP390 from Adafruit today and hooked it up to a Teensy 4.0 and got the same results that you showed in your post #13. Tried a couple of things but was failing but then I went to...

When I was looking at that yesterday it didn't make a lot of sense to me. Looked like in the configure function it tested the JEDEC (so that should be 2 reads) for each position of the ram. But then it just called off...

The pins look correct but as I mentioned are hooked up correctly to the Teensy 3.5 For SPI1: sck -> pin 32 cs -> pin 31 miso -> pin 1 mosi -> pin 0 then of course you have: #define RFM69_RST 24

Found my RF69HCW radio from Adafruit (https://www.adafruit.com/product/3070) and ran the sketch the modified rf69_tx_demo sketch that I mentioned but configured for SPI and I can't seem to duplicate your error about not...

@KurtE Looks like we cross posted :)

Just taking a quick look at the examples and the lib for the RH_RF69 looks like you can specify SPI1 or SPI1 (default is SPI). For instance, from the rf69_tx_demo.ino in the Teensy example folder: //For Teensy 3.x and...

Well, glad you found a potential issue but not good it a short on the castellated board. Hope you can get it fixed.

Morning @KurtE Was just going through the thread and you new message popped up. Why back when when we did PSRAM as a standalone library after Paul gave us the starting code and Frank B expanded on it we were using the...

@defragster - @KurtE Just pushed a minor change to the readECC function in the lib to correct an addressing issue that was bothering me. Yes I am feeling better now.

Just catching up as been a bit out of it for several days. But I just ordered one from Adafruit and should be Tuesday afternoon.

You as well Frank and all my other friends and forum members!! HAPPY NEW YEAR 2021 Stay safe and healthy :)

Great that is working and yep no more manual updates :)

You all sound like you are having way too much fun with MTP :)

Maybe not with Arduino 1.8.10 but definitely between Teensyduino versions. I just tested the sketch with 1.8.10 with TD 1.50 and didn't receive a compile error. So would recommend updating - besides a lot of things...

Right now ECC is enabled but BBM is not enforced :) Basically right now it lets me know when I messed something up with devel code - when I see ECC errors I go check what I did. Right now its pretty stable.

I just compiled the SimpleEncoder sketch on the T4.0 and the T4.1 and didn't receive any error messages from the library. Right now I am using Arduino 1.8.13 with the Teensyduino 1.53- beta5. So really need a bit...

thanks Kurt. Thats kind of what I was thinking as well but think its going to be Paul's call.

@defragster - @KurtE I think I figured out how ECC bad block management works for at least the W25N01 and probably the W25M02 (think I have to fix something with readBLUT function though - maybe). But makes it alot...

Oops = forgot to push the button. Just did it now - LFSIntegrity PlusNAND branch. Thanks :)

@defragster - @KurtE Pushed a update to the NAND lib to fix a couple of bugs I have in readECC function (SPI and QSPI). Going to see what happens if I add an error to the BBLUT table and enable BBM. Going to take a...

@defragster Runs look good - just about matches what I saw on the standalone versions. Thanks for adding :)

@KurtE = looking good. EF7020 - Winbond W25Q512JV*IM (DTR) from the list of FLASH chips :) Can't wait to see QSPI.

Ok. I was right SdFat allows you do cout stuff. Replace Streaming.h and #define cout with the following 2 lines: #include <sdios.h> // Serial output stream ArduinoOutStream cout(Serial); Now no need for...

Actually now that I am thinking about it doesn’t safari have a streaming class. The cout came from the original bench sketch

Oops see it now. Answered on the beta5 thread. https://www.arduinolibraries.info/libraries/streaming Haven’t tried this version yet and I may have made some changes to the orignal

Sorry didn’t see that yet. Comes from here http://arduiniana.org/libraries/streaming/. I can’t remember if I made changes to it... been awhile. But looks like someone else is maintaining it ...

Great you got it working this far. Think I read in another thread on MTP that support for events on T3.x wasn't implemented yet?

Did a modification of the Bench sketch but using LittleFS_Program, and added in a random read timing loop. Write/Read blocksizes are 2048bytes and I used random to jump around the file (16k) in 2048 byte increments:...

First thanks for the explanation. Really does help. Have one question what is your definition of "MANY", have a feeling my definition would be a lot less than yours :)

Out of curiosity I ran the same bench sketch on the N01, N02 and the W25Q512JV on the SPI memory board: SPINAND SEQ BENCH TESTS FILE_SIZE_MB = 5 BUF_SIZE = 2048 bytes --------------------------------------- N02...

@defragster I was reading Paul's post in the beta5 thread and remembered that I put together a benchmark sketch based off of the SDFat benchmark sketch. So decided to run in on the N01 chip: LittleFS Test Device...

@defragster Bad wording since I didn't really explain. Wondering why the M02 can only reliably work at 55Mhz when using SPI as opposed to 75Mhz say.

Just ran a quick test using a N01 Flash: Total time to erase to the 1Gbytes is: Done Formatting Low Level in 4240999 us. or 4.2 seconds from 1024 blocks of 128K. Looks like total wait time for each block erase is...

@KurtE Depending what sketch you are using you might have different speeds set up. If I remember right PSRAM/QPI is running at 88Mhz and if you are running SPI in from LittleFS its using 30Mhz. Are you testing the...

A couple of things. Both PSRAM and QPI use a mix of 2 pin IO (IO0 and IO1) and 4 pin (IO0, IO1, IO2 and IO3) commands. For instance JEDEC and read/writeregister only use IO0/IO1, READ/WRITES use IO0-4. So what you...

@KurtE Looks like it is working from what I can say for the JEDEC anyway. MOSI is showing the command 9F which is the read JEDEC command and then it reading 3 bytes from the MISO line which is 0xEF, 0x40 and 0x18. ...

@KurtE - @defragster Did just test the 512MB, 1GB(n01) and 2GB (n02) on the memory board with a T3.5. Running a couple of tests from LFSIntegrity received no errors and everything seemed operational. Just another...

Afternoon @KurtE Maybe a bad connection? I have been testing some of chips including the M02 on breakout I put together for QSPI. Curious. Which chip are using. M02? To be honest... would try the prebuilt version...

Tell me about - soldering those 0.10" pins are a challenge. About as small as I want to go with a soldering iron! But getting better at it :) @KurtE - @defragster - @Paul Getting ready to push an update to the...
