Hey @PJ_Glasso ,
Thanks for a lead.
Tired to first test using a basic QSPI flash code present in SEEED_nRF52840_QSPI/QSPI_New.ino at main · PMCheetham/SEEED_nRF52840_QSPI · GitHub , got the expected output but unfortunately whenever I try to use flash of the seeed studio board it is getting bricked meaning I can’t detect the board on serial port anymore.
So i guess it’s a risk to toggle with flash memory of the board. Any other solutions or resources by yourself or anyone else is highly appreciated.
