Getting the following error when do make run. ayushman_ubuntu@UbuntuLTS:~/caravel_board/firmware_vex/nucleo$ make run mpremote connect /dev/ttyACM0 exec "import machine; machine.reset()" Traceback (most recent call last): File "main.py", line 2, in File "io_config.py", line 1, in File "nucleo_api.py", line 3, in ValueError: incompatible .mpy file MicroPython v1.19.1-616-g5987130af-dirty on 2022-11-20; NUCLEO-F746ZG with STM32F746

Type "help()" for more information.

Maybe an outdated version of the mpy files on the device?

Did you try:

mpremote ls

ayushman22git commented 1 year ago

This is the response I get with mpremote ls

@ayushman22git can you give more details on how you connected the board to the host computer?

proppy commented 1 year ago

@ayushman22git did you also run:

make compile
make copy

ayushman22git commented 1 year ago

@proppy I connected using the CN1 connector on Nucleo to my USB host. Utilized mpremote. I had not run these 2 commands. However I have now run these commands. the following is the output

Copy is not proceeding beyond this point. However, after several iterations the copy operation halted as in figure 2.

Not proceeding beyond this point. When interrupt this at times I see mostly the following output. It seems to hang. In some trials, see earlier error message with make run as well.

another possible workaround is not not compile mpy file and simply copy py file around: https://github.com/proppy/caravel_board/commit/d19877f864fbc368b3874f8979909bdc99b4f162

@ayushman22git one gotcha that @mattvenn figured out during his recent demonstration, is that a more reliable copy is possible by:

reflashing the board with make F746ZG
connecting another usb cable on the opposite side of the st-link connector
mounting the corresponding volume that's showing up
updating the path to the volume in https://github.com/efabless/caravel_board/blob/main/firmware_vex/nucleo/Makefile#L9
copying the file using make copy2

proppy instructions are correct and are now included to the README
