Good day Nordic people, I am facing a problem when erasing or writing to internal flash memory after enabling softdevice. here the details and tests:
Setup: - GCC, arm toolchain, make files under linux OS. Visual studio code for editing.
Exact problem: - when trying to erase or write to internal flash, it throw an exception at PC address 0x15074. sure this after SD enable.
Testing and Tries: - Am using SD flash APIs. - I tried to access sd flash function directly and within fstorage APIs. - I tried Segger Fstorage example and it was working fine so i moved this example to my setup but no luck. - i tried to disable softdevice before Flash operation and enable after finishing, it is working sometimes... in all cases i don't recommend this way of solving this problem. - before enabling softdevice, I was able to master flash operation without any problem. - I tried many configuration for sofdevice lf_clock, RC, XTAL and SYNTH
I think, there is a missed configuration is done by IDE like Segger, I didn't use it. But what is this configuration, i don't know.
Hi Simon, sure, it is a precaution to check the address. I have divided the memory in a custom linker file and i am accessing 0xf4000. here is memory partitions:
