flash.mk openocd script can't open target binary

[Brandon-Hurst]

Attempting to flash my MAX78000FTHR via "make flash.openocd" as described in the User Guide.

Here is the output I consistently get:

I'm able to manually run openocd/arm-none-eabi-gdb server and flash the binary just fine, but the flashing script referenced here is unable to open the binary file. I also tried this from an Administrator-level bash environment.

Hello, I also have trouble similar to that. May I just ask, did you also encounter a gdb connection error?

[Brandon-Hurst]

Hi Ethyl,

No, I did not. I was able to flash my app over gdb-openocd. I ran it like it explains in the User Guide, below for your reference:

In one terminal window, run:
openocd -s ${MAXIM_PATH}/Tools/OpenOCD/Scripts -f interface/cmsis-dap.cfg -f target/max78000.cfg

In another terminal, cd into your project directory and run arm-none-eabi-gdb then run the following commands:
target extended-remote :3333 connects to your running openocd client
file build/max78000.elf will set the target binary to load
load will load the flash

I was also able to flash with just OpenOCD by essentially running the same command as the flash.mk but on the command line.

Incidentally, I also installed onto a VM for Ubuntu 22.04 yesterday and the flash.mk process works just fine on Linux. So it's perhaps a Windows issue.

Thanks @Brandon-Hurst, just replicated the issue. It does seem to be specific to Windows/MSYS2

Hey @Brandon-Hurst just merged a fix into main. Should be working now

[Brandon-Hurst]

Yep, tested and working. Thanks Jake!
