Always a pain to plan soldering in advance for pin or socket and top or bottom - and picking the wrong combo leaves a hassle to deal with :( If properly wired - and the jumpers are well connected - the jumper type...

T_4.1 with KurtE code ( and the p#467 Volume Name edit ) - on unpowered hub just the two partition 64GB Flash works! >> NOTE: putting this flash in Win machine mounts both partitions/drive letters also. Pulled SD card...

Using unpowered Hub and the 64GB Flash with 32 GB recovery Part - the 2nd part shows using KurtE code: Notes on output below: > there are about 300-400 pages of files displayed in TyComm on the recovery drive - does...

Some hacking here - esp with my odd powered hub that has internal device #1 of a 120GB HDD - then as coded it doesn't look beyond msDrive1. Also odd about the hub as before - once enabled the Hub/HDD backfeeds power...

PR prepped to update with latest and LFSIntegrity got pulled into PJRC tree. Copied those files to git.defragster\lfsintegrity so they match now for changes going forward.

Finally built here ... swapped PJRC git USBHost into sketchbook/libraries ... still fail Deleted that to use the td1.54b7 installed copy and IT BUILDS! { Maybe re-using the sketchbook folder left some debris? } ...

This was pulled for use :: github.com/KurtE/USBHost_t36 >> "This branch is even with PaulStoffregen:master."

Odd ... Maybe https://sectigo.com/cps-repository hasn't reported the cert details to MSFT yet? I see these unfilled filed looking at the exe?:

tCode is my sketchbook folder for local installed libs to replace any other installed libs. This is where I dumped the downloaded ZIPS from the github pages. Used: T:\tCode\libraries\USBHost_t36 Not used:...

Awesome. Let me know if anything changes - the git.LFSIntegrity should match? We can manage any updates but that helps formatUnused look useful and improves/updates LFSIntegrity.ino.

The list of LIBS used looked right ? Unless I have an old copy? Seeing this makes it seem like a prototype is missing from ??? T:\tCode\libraries\USBHost_t36\MTPDevice.cpp:318:6: error: 'MTPDevice' has not been...

YAY for you :mad: - what am I missing :(

Just poking at the downloaded EXE I got to a dialog - Install Certificate on Machine (versus user) ... Hit the download again and - same grief. So the SmartScreen doesn't seem to ask the machine if the cert is...

That is a hack that doesn't help the desc.h issue. It came up a beta or so back and it handy. Anything there adds to or overrides anything in the base boards.txt. Offline about now - will look for USBHost/MSC/MTP...

@mjs513 - if these lines are in this file (thanks FrankB) : ...\hardware\teensy\avr\boards.local.txt teensy41.menu.usb.mtpserial=MTP Disk Serial (Experimental)...

That 'verbose info looks like the linker output as it parses the ELF with this line added to build.txt? ## teensy41.build.flags.ld=-Wl,--print-memory-usage,--gc-sections,--relax "-T{build.core.path}/imxrt1062_t41.ld"...

I also reported the download site as safe again in the process. There was a pre release test version I did that on as well the other day - and did that again this time when I tested to see if that version might be...

@Paul - for reference on this new Win 10 machine that doesn't like the NEW 2021 certificate I just downloaded this file with NO WARNING from browser or the system or BLOCKING - even the EXE runs without 'UNBLOCK' with...

All seems well with the Beta 7 - ran the IDE some to good effect. Then back to in editor command line and all is well. re #1 :: Teensy.exe cycling between 0.0%. 0.1% and rare 0.2% of CPU usage on Windows 10...

@mjs513 ... Made a github.com/PaulStoffregen/LittleFS/pull/8 to update from this fork: github.com/Defragster/LittleFS

@mjs513 ... TD 1.54 b7 came out with OLD LittleFS in place. Is the current github.com/Defragster/LFSintegrity up to date for a complete pull to PJRC github.com/PaulStoffregen/LittleFS I need to put it back here...

Opps - that explains the change after new install. So now back to the errors in post #438 from that posted code ? T:\tCode\libraries\USBHost_t36\MTPDevice.cpp:318:6: error: 'MTPDevice' has not been declared void...

Thanks, that was the link I forgot - though I had downloaded it yesterday I see. Busy week downloading on New Computer setup - over 30 things in there ... Looks like some mystery ... sketch from post #433 fails big...

@all : new images of the updated T_4.1 is online :: pjrc.com/store/teensy41.html#pins

Yes - see : store/teensy41.html#pins That shows the Arduino pin numbers for the SDIO pins

Hoping to catch up with this soon - USBHost , MTP, MSC ... will have to find the current common sources and stop being distracted by life and new computer setup.

Just put a note on Frank_B's PR Print Hardfaults #535 - that would be good to have in Beta 7 release so a thread could be started to discuss and put it to use on T_4.x's. @KurtE - 4K bump was in the error detection...

Following p#85 shown above. It looks like RAM calc goes in 4K chunks? Not a code multiply but from ?? :: "data = elf_section_size(".data");" Using this for RAM is too much - like anything higher than 464 :: char...

If you over alloc in an OBVIOUS way - or even barely: The build breaks in ld.exe before getting to run the teensy_size.exe: ...

PR updated for only resources in Error to show in console COLOR. github.com/Defragster/teensy_size/blob/patch-1/teensy_size.c

When there is an error to result in a '-1' exit - the text "teensy_size: " should NOT be printed on the Error line so it gets proper color coding.

Quirks indeed ... It was noticed in beta IIRC that there was LARGE timing asymmetry in I/O value changes. That seemed to go away - or at least not be super extreme - perhaps that was early when I/O went from 'slow'...

And for mtp-test - looks good?: teensy_size: Memory Usage on Teensy 4.1: teensy_size: FLASH: code:140560, data:13176, headers:7212 free for files:7965516 teensy_size: RAM1: code:163840, variables:37696 ...

Still looks good. this shows here? Maybe just a local issue - but %lld fixes it. teensy_size.c:54:43: warning: format '%ld' expects argument of type 'long int', but argument 2 has type 'size_t' {aka 'long long...

Well everyone should use Verbose mode. For those using non verbose wasn't expecting this detail to be ejected. But if the normal output gets clipped then that won't show for non-verbose ... Opps Though making it...

Good to know - so that is (current) 'fixed' MCU overhead - not something user code will affect - but takes space on the FLASH.

@FrankB - thanks for the EXE! LFSIntegrity shows this when added to TSET cmdline build - when using EXTMEM char buf RAM LFS Media: FLASH: code:86092, data:10160, headers:7212 free for files:8023000 RAM1:...

That looks really nice for used resources output! Not sure what 'text_csf' / headers is telling me?

Quick search at Sparkfun and Pololu don't show they have any PDM's that pop up ... The only breakouts at Digikey are two Adafruit MP34DT01-M ( and other one ) , though they have many PDM,Digital mic chips.

AdaF NRF Sense unit uses : PDM Microphone sound sensor: MP34DT01-M - PDM sound sensor. And their adafruit-clue - uses the same Mic. They link to Arduino lib arduino.cc/en/Reference/PDM that mentions "such as the...

I was wondering the point of the code as well - indeed tone or PWM might give better results with less overhead.

Is this the whole purpose or just a part of the project? Is any code needed to run in loop()? Do the frequencies ever change? A Float value can be passed in and it looks like a value down to 0.7291667 (?) will work...

Looks like there is an update to some linux versions that resolves the issue - not yet provided to be applied to the problem versions? There was as noted a passing time where my prior Win 10 machine would...

@WMXZ - re p#883 - have you tried with KurtE's latest p#880? Just back and not tried ... Does it prepopulate the empty slots on Windows with RED when no disk is installed?

If LFS tracked or informed on abandoning a block we could use that info. When they want a new block they ask for 'Format' before use, when they are done with a block they just move on AFAIK. But after reading and...

Yes - two copies - one in prior LFS and one added to the NAND code. Not all media uses it : FRAM, RAM, PROGRAM. RAM is a NOP - not sure about FRAM to just write may take less time to just write blank on request,...

On one of the NAND SPI chips LFSIntegrity had run leaving lots of dirs and files - died on delete of folder 24? Teensy still responds to USB CMD 'f' to toggle that. Running the new LFSIntegrity a recursive...

@Paul: NOTE for SD update to SdFat : transferred Arduino/Teensy drive contents to new machine here > Build pulled in Adafruit_SDFAT library instead of the Teensy one, had to delete that ( used for their NRF family )

Yes, the meaningful change is to blockisBlank() in two places ( NAND and LFS other) and the call change in formatUnused. I had a good compare post of the times - forgot to post as I ran off - came back with more info...

@mjs513 - KurtE - Paul ... @all: Just pushed up an update to : github.com/Defragster/LFSintegrity In the process the NAND branch was deleted. { New machine new entry to github - still stuck on some Pull Request...

Teensy is awesome - and TyComm makes it better. TeensyLoader is good but matching the IDE focus on a single board leaves room for improvement with multiple Teensy. Especially when it comes to SerMon! And TyCommander...

See LittleFS thread for updates. Next step to include new and improved unusedFormat into MTP-test - no longer wastes time reading whole block for format test - so disk doesn't go offline (like other formats Q and LL)...

Updated to new computer - managed the "T:" on old computer to the new - was a stand alone SSD - now mapped into T_DRIVE folder as T: so no changed needed for TyComm or TSET setup - even the IDE with TeensyDuino...

Glad that works. There are pending changes to TyCommander where it will pass the RTC time on upload - not sure that is on github. But that shows something specific to starting the loader - not the system otherwise. ...

@KurtE just put some #20.??? version of Ubuntu on a machine IIRC - not sure if this shows there? NOTE: I saw this on Windows 10 for a brief period some time back - it just 'went away' - that is Doubly unhelpful...

Because the uint64_t passes two sets of 32 bits and the printf as used told it to read them 32 bits at a time. One got the low 32 bit value held and the other saw the upper 32 bits of zeros.

Online with new computer today - actually remote desktop from new to the old ... now can move old to remote desk and put new one in place ... So not much done Teensy-wise except on this new machine copied over...

Also note 'u' is unsigned and 'd' is signed. Both val and m are unsigned ... unsigned long n; long m; printf("%lu %ld", n, m);

Cool Context Menu Format - How Handy. Good Info. Makes sense now and with cover of Dialog all should be well - of course unusedFormat - same timing as LLformat and no disk disruption so it should not need to...

Question: is it right to assume that no new block is allocated in LFS without an ERASE? Perhaps it can do a partial block update program 'in place' - but it cannot allocate/use a new block without calling 'erase' on...

Looked a bit more at the callback code? Not seeing it activate from sketch? Narrowed down to single FLASH5 drive - no rpints from the mtpd_format_cb? MTP_test sd_addFilesystem: 0 20005040 sflash5 1 SPIFlash...

Made the 'lookup' change - got a couple of copy/delete cycles of T_4.1 - then it died on 64MB SPI. Was probably formatted up front? Using new code but : g_lowLevelFormat = false ... SendObjectInfo: 7 26 20004180:...

Quick format only wipes LFS data, like LLformat. But Quick doesn't prepare any blocks to a formatted state like LLformat or formatUnused, so write will still take time when block requires format before use. If the...

Was USB the power supply to the T_4.1? It can only supply 500 mA? - and the onboard regulator IIRC can convert more than that to 3.3V - but heat dissipation is pushed beyond that. Was the current drawn by the T_4.1...

Bus rules apply? i2c each device with a unique slave ID can share the bus and be addressed in turn. SPI each device with a unique CS pin for chip select can share the bus ( as long as it has tristate hardware on...

unusedFormat() the best option as noted for media life for reasons noted and leaving media mounted. For that formattedUnused() option it could offer 'delete All' if the user really wants to start fresh - should have...

An example of formatUnused() in setup(). Before Serial online if format unneeded or fast it continues startup. Edge case not tested but hopefully safe. Until the Disk is FULL I can copy all or part of T_4.1...

Yes, need to be done before trying to MTP mount the Teensy Showing troubles with any delay once mount started ...

Got this 8MB SPI Prop working in LFSIntegrity. Ran to dirty all blocks then repeated after perhaps 'q' then unusedFormat(): Huge varience 5-6X if Formatted or not with 20+ms per block to format (IIRC). '#' :...

That is slow! What does LFSIntegrity show on the media? Speedtest with 'g'? Then 'f' and 'g'? <edit> : My prop mem on CS==6 - not showing up?

Indeed 'r' reset does not help restore a missing storage device. In fact if an explorer refresh is done then NO devices are shown?

Okay - they are on 3,4,5,6? What's wrong with 3,4?
