Chip hangs on flash erase

[Cyril Hruscak]

I'm using custom board with 32MHz oscillator and S110 SD 7.1 (SDK 6.1). Somteimes (quite rare) the chip completely hangs when calling sd_flash_erase in pstorage.c. Only hard reset recovers the chip.

Do you have any idea what could cause this?

What do you mean by hangs? it could be simple APP_ERROR_CHECK fail case. Did you try to debug it and pinpoint exactly where it happens?

[Cyril Hruscak]

Sorry for not being clear. The APP_ERROR_CHECK is never reached. The function never returns.

need to check your code, can you attach the project, i can try it on my desk. If you are uncomfortable putting code in public, then send me it as an attachment in PVT message.
