@KurtE Was just looking over your code snippet so this is a question - it may be buried but I don't see where you are setting up expartVol/partVol .begin for the different partitions and then setting a mscfs based on...

Trying a whole host of things but no luck. Hate issues like this reminds me of UncannyEyes! Going to go back and play with MSC/MTP!

@luni Found the problem - the program for doesn't like going to USB1 when using a T3.5 and T3.6. Removed it and got everything started working as before. Did test with a T3.2 but it hanging somewhere so the DCC++...

Funny it worked with the code I posted now must have did something to make it fail. Going to run a test just to see with time.h. EDIT: Something else must of broke. Just this test sketch and it works fine: //...

Nope nothing else gets printed as I am playing. BTW will it work with a Teensy 3.x Remember when I said it was working for a T3.5 well now its not working - argh. - no start up info from timer.h and no signal.

@luni Seeing exactly the same thing on startup as you: init 0x0 setPeriod(58) attachInterrupt() start out of curiosity I switched the prog track to use pins 3/11 just in case. No difference

@KurtE Did try and putting asm("dsb")'s in different places associated with the interrupts but still had the problem. Tried playing with volatile's as well but no luck.

Ok now have another interesting thing going on. I wanted to try with a Teensy 3.6 but as soon as turn power on with the sketch loaded the T3.6 is sending signals to the lock to move but its not suppose to. The...

Will give it a try - just after a fresh pot of coffee.

Oops - thats @Frank B's library = I added it get freemem for the T4.1: https://github.com/FrankBoesing/T4_PowerButton Sorry about that - forgot I was using it so distracted with the other problem.

Ok lets see if I can explain this without tripping over myself. A virtual timer is set up in Timer.h that calls off to IntervalTimer that does a attachInterruptVector. The sketch then calls off to: ...

Morning all Actually no, didn't get a chance to look - too many other distractions last couple of days :) I agree with you Kurt 100%. Oh - one thing I noticed is that if you put in a SD Card in a USB adapter...

Serial monitor seems to be hanging again similar to what happened in T4 beta testing: https://forum.pjrc.com/threads/54711-Teensy-4-0-First-Beta-Test?p=213179&viewfull=1#post213179 If I run this sketch: void setup()...

Thanks thought crossed my mind - so I tested yesterday down to 24Mhz. But as a double check after your suggestion I just tested at 150Mhz - still stopped after a couple tries. Even tried tried changing compiler options

Morning all @defragster - gave your mods a go and all seems to be working. 1. SSD 120GB - 2parts, extFAT/FAT32 2. SD CARD in adapter - 32GB - 2 FAT32 parts 3. 2 GB Thumb drive - 1 FAT16 All worked without a...

If anyone has any ideas please let me know. Ran of ideas on how to further debug.

@defragster - will let you do it = going get some zzz's now - been up since 4am

Damn - thought I posted the fix: // VolumeName.ino // An example of how to retrieve Fat32 and ExFat volume names using SdFat. // Works with SD cards and USB mass storage drives. #include "Arduino.h" #include...

Ok here is the fix for extFat: Waiting up to 5 seconds for USB drive Initialize USB drive...USB drive 1 is present. msc1 Partition Table part,boot,bgnCHS,type,endCHS,start,length FAT32:...

@defragster Wondering if its an issue with MSFT formatted drive. I put a 128GB SD Card in a usb adapter with 2 FAT32 and 1 extFAT. But looks like the exFAT is failing for some reason; Initialize USB drive...USB...

Now looking at the waveforms between the T3.5 and T4.1 when it works the command takes about 1.2seconds to complete and they look alike (Used a Salae Logic Analyzer). When it fails on the T4.1 the signal just keeps...

@KurtE Fantastic. I was playing with and trying to make it work like FAT by opening the root directory but failed miserably. Where did you find the rootDirStart?: msc1.usbDrive()->readSector(partVol.rootDirStart(),...

Just gave it a try and works for me. We all are really hacking away - but its working at least so making progress. Not sure we are supporting FAT16 - or should we? As for different types of FAT32 codes that easy...

@KurtE Fixed this now works for USB devices: msc1 Partition Table part,boot,bgnCHS,type,endCHS,start,length exFAT: 1,0,0x20,0x21,0x0,0x7,0xFE,0xFF,0xFF,2048,204800000 FAT32:...

Out of curiosity I did add a print directory (LS) for the fat just to see if it work: msc1 Partition Table part,boot,bgnCHS,type,endCHS,start,length exFAT: 1,0,0x20,0x21,0x0,0x7,0xFE,0xFF,0xFF,2048,204800000 FAT32:...

@KurtE Got it partially working msc1 Partition Table part,boot,bgnCHS,type,endCHS,start,length exFAT: 1,0,0x20,0x21,0x0,0x7,0xFE,0xFF,0xFF,2048,204800000 FAT32:...

@KurtE - @all Finished my diversions this morning and guess I am going to start playing with partitions again. This stuff is giving me a headache to be honest - a lot of pieces to the puzzle. @defragster Glad...

Thanks Kurt - right now by brain is mush working on multiple things at a time :) Need a break before getting back into it.

Question: To set up a volume say for an exFat partion I do a: expartVol.begin(sd.card(), true, 1); for an SD Card. Now, if I am using a usb drive (non sd). What do I do for a blockdevice or pointer to the...

Try pulling from Paul's repository for USBHost_t36 - I switched over to that for testing. Just looked looks like its like it should be the same though.

@defragster Maybe its using an outdated USBHost_t36? or maybe try it from Arduino IDE : Using library UsbMscFat-main at version 1.0.0 in folder: D:\Users\Merli\Documents\Arduino\libraries\UsbMscFat-main Using...

@defragster I am assuming that those libraries in T:\tCode\libraries\ are some linked to the libaries in T:\arduino-1.8.13_t54\hardware\teensy\avr\libraries?

Ok cool was just looking at this now - so now don't have to. Do have to so some testing with the changes though in MTP and standalone :)

Ok here is one for you all Out of curiosity I just downloaded it again but used Firefox. No issues with defender and my Norton pop-up came up and said it was a safe file. I added that rule a long time ago. Now -...

Not 100% sure. In post #435 @wwatson mentioned that the only thing you need in your libraries folder is: https://github.com/wwatson4506/UsbMscFat.. I did delete all the old MSC files - uSDFS, MSC/MSC2 etc. so that...

@wwatson - @KurtE - @defragster Just ran your test sketch in post #433 and it worked like a charm. Recognized exFATs and FAT32 to get the volume name. Have to go find my hub to test with again - keep loosing...

@defragster Nope the those lines are in my version. Note - never created a build.local.txt file that I remember but then who knows may have did that a long time ago and just got use to it being there. Going to add...

@defraster Don't remember ever having a boards.local.txt file there before. Anyway that is in there now for all Teensy's not the the T4.1

Item #1: teensy.exe is staying around 0% with periodic jumps to 0.1%. Java Platform SE Binary goes between 0% and 0.7% Item #2: see post #10 A couple things for Beta8: 1. USBHS_USBCMD_ITC(0) in usbhost_t36...

Did notice the new memory usage in both Verbose and non-verbose. In verbose I am seeing this additional info: Linking everything together......

@Paul Just downloaded Beta7 and pretty much saw what @defragster saw in post #4. I did one additional step. Before telling defender to Keep file I clicked on REPORT THIS FILE AS SAFE: Once you click on report file...

@KurtE Funny when I put in my SSD it showed the contents of the first partition as I expected. I was rummaging around mscUSB but I didn't see any linkages back to SDFat for the Volume commands that we need. So...

Not yet. Not sure how much of the vol and partition stuff is exposed in msc. Haven’t looked at yet

@KurtE Been searching the code and the help system as well but to no avail. Nothing I have found seems to return the volume name. Think @wwatson mentioned in an earlier post that he was doing something to get the vol...

@KurtE - @wwatson Decided to play around with the BufferedPrint example to see what it takes to write and read files from the partitions. Did manage to create 3 partitions that I can test with; SD Partition Table...

@KurtE Sorry for the delay in responding. Was busy playing and watching more snow fall :( Any tried to modify formatter but haven't broken the code on that one and wound up messing up my partitions on the sd card...

Taxes - yep - already did mine. Anyway get the volume directory was relative easy. SdFat version: 2.0.5-beta.1 Assuming an SDIO interface. type any character to start init time: 22 ms Card type: SDXC

@wwatson Thanks for the changes will play more with it tomorrow. May try to do a list files but intent really was to see if and how to get access via sdfat. But the use of sd.card was the key

Hopefully no more issues. Hope that list is getting shorter but have a feeling it’s getting longer.

Should have mentioned. Running Ubuntu 20.04.02LTS 64 bit on the PI4. Don't really have any other Linux systems. Probably can did out a RPI3 and see what I have on it and give it a try if you think its worth it?

Ok - just tried it on a RPI4 and its now working. Guess the order matters - 00 versus 49. Forgot to document but think you added an extra rule as well to the file.

First don't despair. I have had many UBLOX modules working with the Teensy (most 3.2 and up) and never had a problem. The first thing I usually do is use a Hardware Serial Port as opposed to using Software Serial. ...

Thanks - the dummy that I am. So with that ran it but I created 4 volumes 3 are FAT32 and 1 is exFAT. This is running the SDInfo without Partition info set up: SdFat version: 2.0.5-beta.1 Assuming an SDIO interface....

Morning @KurtE Was trying to implement your changes and found you already implement them in the repository example so.... Using just 1 MSC object ran into a couple of problems with some devices: 1. SD Card using a...

RE Partitions: SDFat only supports single partition. See https://github.com/greiman/SdFat-beta/issues/69

Have fun. Make sure you use @KurtE's branch. https://github.com/KurtE/MTP_t4/tree/MEM_send_object_large

@KurtE Was poking around SDFat and not 100% sure it directly supports multiple partitions. Why, Blockdevice* dev I believe has to point to the SDCard but doesn't appear we have access to that. Bill points to card into...

Just including this for reference: https://forum.pjrc.com/threads/55821-USBHost_t36-USB-Mass-Storage-Driver-Experiments?p=271015&viewfull=1#post271015 on using partitions.

@KurtE - @wwatson Not sure where to post this (kind of crosses - Integration Thread) Anyway not sure how this would work but SDFat does have a FatPartition Class that looks like it would allow you address...

@KurtE You just knew I had to download your changes to test MTP with MSC (UsbMscFat). Anyway hooked up my SSD and low and behold it showed up in MTP and was able to do several things: 1. Copy files from the SSD...

Morning again - can't sleep so catching up As for restarting. I did close and reopen the IDE but didn't disconnect the Teensy which was probably the issue - didn't even cross my mind to unplug it. Probably a...

Morning @KurtE Sorry I didn't get to this yesterday - still recovering a bit and had another distraction. I agree with 100%. For the things that you described those are the things that should/could be...

This is the latest version that I am working with and should give you everything you need: https://github.com/wwatson4506/Ra8876LiteTeensy, for the RA8876

@wwatson Just downloaded UsbMscFat and so far examples working a couple different devices I tried - 32 thumb drive, SD Card in adapter and a SSD drive. Here some info from one of the examples: init time: 1341 ms ...

For comparison in the sketch I was using I have slightly different timing for messages: heartbeat = 1Hz (think this interval is fixed), AHRS (roll, pitch, yaw, rotation rates) every 100ms, GPS (lat, long, vel, alt,...

@KurtE My suggestion would be that if it is a specific library related issue it should be on the appropriate thread. For instance if LittleFS is formatting correctly or not recognizing a flash chip it would go on...

ok - as shown didn;t really work for me - but then I really have no idea with Linux so just used gedit to create the file. Restarted and it now works with serial monitor as you said. Maybe Paul can add it to list of...

@KurtE getting an error when I try to execute your first line: ubuntu@ubuntu:~$ /etc/udev/rules.d$ cat 99-hidraw-permissions.rules bash: /etc/udev/rules.d$: No such file or directory EDIT: never mind figured...

@KurtE Not to the serial monitor. Either output to textEditor or directly into the IDE window - depending which I had selected (active). But I did get output even when I had keyboard printing. Have to go finish...

Can confirm that the app works with 20.04.02LTS. Tried the same sketch as @KurtE and when I selected Serial+Keyboard... did get out on the Serial monitor.

Of course But just remembered the password when I was setting up with the new version :) Getting the updates now.

Installing fresh Ubuntu on my PI now to see what happens. Using 20.04 LTS instead. Looked like 20.10 support ends april 2021. Using the Raspberry Pi imager then will do the updates. And before you ask why fresh -...

Well using the Arduino IDE I just compiled your sketch with no errors or warnings. I am assuming you have to select Teensy 4 in platformIO so only other thing is are you sure you are compiling for Teensy 4. ...

It sounds like PlatformIO is using an old version of the Servo library. I don't use PlatformIO so you may what to report it to them. You might try downloading the latest and greatest Servo library from PJRC and...

First nice job Brian on the Mavlink wrapper - have to look at it more if I get back to mavlink :) @mar to your question - not really sure what happened to the references I used but I do remember it was quite a bit of...

Evening @KurtE Just downloaded you latest and greatest and gave it a try. Worked like a charm just as you described it in your post! Of course it was on a Windows 10x64 machine :)

Sounds like you are talking about the old windows defrag idea or propabably format unused?

@defragster Just did the code compare and looks good for NAND. See there are 2 constructors now for blockisBlank in NAND.cpp and that was it for the changes in NAND.cpp. Other than I had some Serial prints...

@defragster- @KurtE NAND Branch if I remember correctly was incorporated into LittleFS packaged with beta6, so that should be the latest. I will take a look and let your know. The only change is to blockisBlank...

Morning @KurtE Just gave new branch a try with LowLevelFormat on the 64MB flash, seemed to format faster: CMD: 100f(FORMAT_STORE)l: 20 T:3a : 5 0 MTPD::formatStore called post:0 Format Callback: store: 4 p2:0 Low...

Just found this in the latest F9P manual for UBX-CFG-MSG: So I think it depends on the protocol version that your UBLOX GPS is running. So I think to be more accurate you are going to have to deal with cases where...

You might try looking at this: https://www.techiedelight.com/trim-string-cpp-remove-leading-trailing-spaces/

No haven't see that as of yet. Haven't played with GPS except for Ardusimple RTK which doesn't use that in its setup. Think you probably would need a firmware upgrade to your existing GPS units to go to that point.

Afternoon all Just downloaded the latest and greatest. Just formatted a 64MB Flash and works much better with the device busy. I do get the format complete window right away and not after complete - don't know if...
