Flasing externally generated hex - KL02z

[simonainsley]

I'm trying to find a free flashing solution for an MKL02Z32V processor.

I'm using a FRDM-KL02Z board as the SWD interface to my own board.

I have an externally generated hex file (built with Rowley Crossworks, I can download and debug using their tools, using the CMSIS-DAP driver. Application code is working fine.

I have followed the instructions in Flash from File: Downloading a file without the sources , having created an empty project targetted at the MKL02Z32V. GDB appears to connect to the debugger, but always crashes giving a Windows error box 'arm-none-eabi-gdb.exe has stopped working,  with the following crash details:

Problem signature:

Output from the console window is below for reference.

Any idea what I'm missing / doing wrong?

Thanks,

Many thanks, indeed code is flashed and running.

Any idea why GDB is crashing, and can it be sorted?

Whilst it's good that it's working, it will be a liitle confusing / irritating for it to happen every time when programming a small batch.

Hello Simon,

It seems you have flash the file into chip. In order to prove it , please download a simple

LED project into it. After download , press RESET button of you board, check whether it can work well.

Hope it helps

Have a great day,
TIC
