Hello,
I need help regarding flash memory read on nRF52840 device, SDk16, SD=340.
I have using the fds libarary for memory read/write in my code for many years now. However, after changing the softdevice from S140 to S340 started causing issues with reading the flash after writing. The same code is used in both cases, for S140 it works fine but for S340, upon memory read after a power cycle, the device crashes and becomes unresponsive.
Is there something changed with this SD? Is there anybody else facing same problem?
Im attaching the fds if that helps.
Thanks.
