  • Hi Andy, 

    I'm trying to bring up a board that has a MAX32625 on it via SWD (and a Segger J-link Ultra+ adapter). When we first got the boards in I tested that I was able to download code to the device and it appeared to accept firmware via Eclipse/GDB/Segger... now that I'm done testing everything else on the board I'm back to actually testing the code and I'm finding that I can't upload code anymore and I get unusual errors that I don't understand. Eclipse (and GDB) complain that there are timeouts when trying to erase flash for programming. So I went into J-Link Commander and just tried to manually erase the flash.  Connecting to the chip works fine via SWD at 4 MHz, it sees the Cortex-M4 r0p1 core, etc.  But attempts to erase result in:

    J-Link>erase
    No address range specified, 'Erase Chip' will be executed
    'erase': Performing implicit reset & halt of MCU.
    Reset: Halt core after reset via DEMCR.VC_CORERESET.
    Reset: Reset device via AIRCR.SYSRESETREQ.
    Core did not halt after reset, halting it manually.
    Erasing device...

    ****** Error: Timeout while erasing chip, core does not stop. (PC = 0x200001D2, XPSR = 0x01000000, SP = 0x20000338)!
    J-Link: Flash download: Total time needed: 20.503s (Prepare: 0.369s, Compare: 0.000s, Erase: 20.067s, Program: 0.000s, Verify: 0.000s, Restore: 0.066s)
    ERROR: Erase returned with error code -5.

    I also tried explicitly targeting the full memory range and asking it not to reset the core (via erase 0x00000000, 0x000DFFFF, noreset) but get the same error. 

    This inability to erase the chip is preventing me from putting firmware on the device. Am I missing something?  How can I revive this chip? 

    Thanks,
    -Mouser
