I tried changing all the modes and changing the SPI bus speed. Still the same issue.
The board is based on the PICO-D4 reference design. I have left out the pull-up on IO12 to enable 3V3 operation.
I also dumped the fuses and I see that the SPI pins are already set.
I tried programming with both the Arduino IDE and the IDF and still the same issue.
Any suggestions would be appreciated.
I tried searching on the forum for any solutions but I don't see any fix.
