Problem flashing FRDM-MCXC242 with LinkServer (zephyr: west flash)

[mw6]

Hi,

I'm currently evaluating Zephyr on the FRDM-MCXC242 board.

When I tried flashing with west flash for the first time (using LinkServer) it worked. When trying to flash for a second time, west flash fails.

I can recover the board by flashing with a JLink probe (west flash -r jlink). Then flashing with LinkServer works again for the first try but at the second try it starts to fail again.

This is my output for the first try:

I have no idea why this would happen. Can you help me?

Thanks,

Hi @mw6 and @Alice_Yang ,

Thank for raising this issue.  This was caused by the Flash Security setting in the FSEC location in flash.  We have an upstream Pull Request to resolve this at https://github.com/zephyrproject-rtos/zephyr/pull/82947.

Best regards
