Hi,
It's possible to get division by 0 and crash the application in flash/nor/nrf51.c.
On line 630 you read:
res = target_read_u32(chip->target, NRF51_FICR_CODEPAGESIZE, &chip->code_page_size);
And then on line 650 you divide:
bank->num_sectors = bank->size / chip->code_page_size;
It's possible for chip->code_page_size to be 0 and crash the application.
It happened to me.

Hi Andrzej,
Thanks for reporting this. It should be easy to fix, I just wanted to check - a code page size of zero is because of a bad SWD connection, yes? It's still a fatal error, but openocd should just print an error and fail cleanly instead of crashing?
Thanks,
Angus
Hi,
I'm sorry for inconvenience, but SF ticket system just made me want to jump off of a window. I'm quite young, but I'm longing to the days of plain text systems. I'm going to write on mailing list.
