I'm trying to erase an STR710FZ2 and cannot seem to erase the chip (with J-Flash or IAR). But what's strange is it doesn't appear to be linked to a specific bank as I *am* able to erase some sectors (specifically B0F6, B0F7, B1F0, and B1F1).
Does anyone have any ideas on what could be going wrong? is there an extra J-Flash configuration step that I'm missing?
This problem began to occur after an IAR programming sequence locked up and I had to abort the program by using task manager to stop the program. Since this failure I am able to connect to the chip via JTAG with the J-Flash utility or the IAR debugger but am unable to successfully erase the flash. Using the debugger I am able to read the FLASH_CR1 register and it is reporting 0xE6000010 which is some sort of LOCKED condition.
