Can't use OpenOCD with MKW24 Kinetis MCU

Hello everybody,

I have a problem using the MKW24 MCU with OpenOCD.

When I plug openocd and I use it, it seems to work properly (it discover the processor successfully):

But when I try to flash it, I always get the following error message:

Arbitrary Flash Configuration Field writes enabled.
Protection info writes to FCF disabled.
Warn : BEWARE: incorrect flash configuration may permanently lock the device.
auto erase enabled
Error: Unsupported K-family FAMID
Error: MCU is unsupported, SDID 0x00009265
Error: auto_probe failed
‍‍‍‍‍‍‍

I don't understand why I have this error message because when I do the exact same operation with the MKW21, MKW22 and the MK22FX512 (the other MCUs used by my company, I can flash the memory...)

What is this SDID ? What does it mean ? Do I miss a configuration file or something ?

Thank you for your help,

Best regards,

Matthieu.

Hello Matthieu.

Which flash programmer or IDE do you used ?

Have you select the right chip configuration when flash ?

And what about the debug interface inside OpenOCD， check it in the Device Manager :
