debug_tt.h looks like something written here ... it can be commented out (as in p#3) or removed. It is not something included anywhere or that generally evolved to anything useful across the evolving MCU's in use.

Only a few known Bluetooth dongles tested to work well - there is a thread listing the ones used and found good. There is a DEBUG #define commented out in the main file, enabling that will provide some feedback on...

The MicroMod Beta thread has development with that version of Teensy. @KurtE of course and @mjs513 did lots of heavy lifting there. IIRC it was mjs513 that hooked up the Processing transfer and sketches sending that...

Indeed, RTOS is its own set of issues/details. Is this RTOS running on a Teensy with an NXP 1062? If so, do EEPROM writes work?

Was wondering if it is due to 32KB code cache? XIP or any Flash code (especially on locked/encrypted) 1062 would need to be made available/plain to run. If that code then blocks flash access during writes (also EEPROM...

@KurtE - Teensy_loader_cli.sln works to build setting Debug x86: Usage: teensy_loader_cli --mcu=<MCU> <file.hex> Hello World - Defragster was here! -w : Wait for device to appear ...

@KurtE - I'll give it a go to confirm it builds here and check back.

Looking at the T_4.1 card here pin 8 is not labelled as SDA/{SDA0}. SDA/{SDA0} is pin 18? And that is on the opposite side of pin 8, the same side as pin 35.

It was asking for some specific 1.45 (?) tool pack. Rather than see if an update would grab it (or it could be found) - the Install of VS2022 Enterprise is done - ready for a reboot

For the heck of it thought I'd see it work ... opps ... VS 2019 ... updating to 2022 Seems last update was to VScode ... not VS.

Any install of TeensyDuino brings all the sources in that directory.

if the number of bytes .available() is known, See: arduino.cc/reference/en/language/functions/communication/serial/readbytes/

Looking at Kurt's sample I see: // mandatory to begin the MTP session. //MTP.begin(); So the problem is that MTP.begin()?

Quick look seems the Adafruit lib doesn't include pin changes. In the Teensy SPI library is this: // Teensy 3.x can use alternate pins for these 3 SPI signals. void setMOSI(uint8_t pin); Do a forum search...

Yes, that is right for pins 11 and 13. If there is a way to specify the alternate pin 14 for SCK in the software, then that can be used. If you chnage one alternate pin that is independant of other optional ALT pins,...

@clinker8 - not had that 'timeout' hit here in some time. After logging back into that thread check the lower left corner of the 'reply' box for "restore" as content seems to be stored on some time period during edits.

Cool ... Looking forward to 1.57b1 and getting back to this. Keeping up was a chore with variety of peripheral adds ... Seems I found the code in progress ...

Congrats. Pin headers do add challenge to the QSPI soldering. @TallDog makes some good stuff - remembering switches better than tossing a good board.

Yes, a suitable converter is needed - watch the voltage before making any connection. From Wiki Voltage levels: Those voltages are not Teensy UART pin compatible.
