IMX RT1170 (EVKB) - Debugging problem

gustavosousabr — Thu, 10 Jul 2025 19:41:36 GMT

When debugging an example in mcuxpresso, it flashes the code and load, but then i receive this message

No source available for "<signal handler called>() at 0xfffffffe"

Im debugging an example application: evkbmimxrt1170_canfd_interrupt_transfer_cm7

Other projects result in the same error.

I have modified the boot device in the board, changed the QSPI to the OSPI. And changed the keys accordingly, i also changed the boot device in the project configuration, in the MCU settings section the new driver is MIMXRT1170_SFDP_MXIC_OPI.cfx

In the gdb terminal i can flash and it looks like i went well, also the load command loads, but when continuing ou stepping it goes immediately to this error. Is there some configuration missing? How can i make the debug work?

Please refer to this document to recover the board: RT board recovery for debugger connect issues - NXP Community

Is the jumper configuration the default? How are you connecting the debugger? Did you make any rework to the board to use another flash?

Best regards,
Omar

Sorry for the delay in the response, i did made a rework in the board for booting with the octal flash (MX25UM51345) and changed the pins accordingly, at first this was for use with PX4 software, and it did work the system booted OK, but for another projects or testing a feature i'm currently implementing in hardware the debugger was needed. So this is the changes i've made accordingly with the board schematics and the actual position of the switches.
