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.
Have you checked what address you try to write to? If you try to write to an address occupied by the SoftDevice an error like this is likely to occur. What SDK are you using for development? The SoftDevice takes up flash up until ~0x26000. This varies depending on what SDK version you're using.
