Glad you got it - there is an #if 0 in setup that will quickly confirm Faults are trapped as configured.
Locked up? Does it do the CARAT printing from timer with "#define SHOW_CLOCK_CARAT 1"? If not then it is...
Is there a good definition of the protocol? All I've found is forum and github discussions - enough to understand the approach, but not enough to write a driver.
Just an FYI: I updated the Volume name sketch to also print out the total size and used size sort of plus elapsed time to get them for the different partitions:
// VolumeName.ino

@the_boss, yes, you could adapt this serial download/flash process to Ethernet. The same person (jonr) who wrote the original Flasher program for T3.x has also written Flasher4, for T4.x, which you can find here:

@mjs513 which code fragment... MSC or MTP... So far in MTP I have not converted the main code to try to do anything with partitions, other than so far I am printing them out and I am able to get the first volume ID.

@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...

That is what I was thinking. In the Linux disks formatting program it lists the partition type as 'NTFS/exFAT/HPFS' but shows NTFS and exFAT as two different format types. Possibly NTFS has a different type...

Just to repeat, I did indeed run the code you shared on a Teensy 4.1 here. I was able to upload several times without pressing the pushbutton. I can’t explain the behavior you have described. But I did test with a...
Would you be willing to share some of your code as an example?
I am interested in standing up bidrectional dshot1200 on a teensy 4.0 as well and found your post while looking for the best way to get started.
Hello. I started a personal project where i design a device that includes these 2 functions:
1) Read/Sniff the EDID data of a DisplayPort downsteam device (i.e. a PC monitor)
2) Send/Emulate the EDID data to the...
@wwatson - not sure, about NTFS here. It looks like both partitions have type=7 which I believe is exfat. although looking at:https://en.wikipedia.org/wiki/Partition_type
It looks like type of 7 could be either. ...
Hey
I know this thread is for teensy 3.5 and 3.6, but I will try my luck. I need to write a bootloader to teensy4.1, so I can program the teensy4.1 through a ethernet port, but according to a thread I started...
@wwatson - perhaps with line #16 on in UPDATE sketch below : //#define SHOW_CLOCK_CARAT 1
That will show MCU running but USB msgs stalled. Have you hacked in the PR for HardFaults just to know if any hang results from...
Directly, no.
But you may ask the friends in this thread: https://forum.pjrc.com/threads/43165-Over-the-Air-firmware-updates-changes-for-flashing-Teensy-3-5-amp-3-6?highlight=flashing
You can't write the bootloader.
You can write to the teensy-flash,( but not to the bootlader )
That works with a normal Teensy - no extra booloader chip needed.
Any luck?
Looks a bit complicated to jump in... I prefer easier things like MSC and MTP :D
Is it easy to setup and see failure when you don't have the hardware? Steps, and what to see when it fails versus OK?

Something else must of broke. Just this test sketch and it works fine:

Weird. The library code seems to be quite elaborated. Would be surprised if it has such bugs in it. Maybe you changed something unintentionally while porting stuff?

Grabbed a fresh 128GB SD card and will make it Multi Partition.
I thought to do something like procesMSDrive(1, msDrive1, msc1); rather than Dupe - but time was limited and wanted to get...
Updated to fix the Fat16, also implemented a one call to find volume label.

Yes, but does it print anything later while you are playing with the commands and getting the error? If so, the library might mess up some intervaltimer settings.
In the SMALL program source code, you should have FLASH_BUFFER_ADDR = (FLASH_SIZE / 4)
In the LARGE program source code, you should have FLASH_BUFFER_ADDR = (3 * FLASH_SIZE / 4)
Is that what you have?

Seeing exactly the same thing on startup as you:

out of curiosity I switched the prog track to use pins 3/11 just in case. No difference
Another quick note: I updated my sketch to the last one @defragster and found it was using the old non working Fat16 code. i.e. the one that was reading the boot sector and appears to always be: NO NAME

That is exactly how c++ template works
the AudioCrosspointSwitch

The "dsb" is only effective for very short ISRs. The one used by the lib is probably long enough. (But this should be fixed anyway I'd say)

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.

Unfortunately I think the larger issue for my application is that I believe it's 1 in, multiple out, correct?

It is not that it doesn't print to serial, it is that the device doesn't even show up on USB or run blink
