Programming QSPI with nrfjprog for nrf5340

[edmcnicholas]

I am trying to program a QSPI flash with a file system.  I have confirmed that my qspi ini is correct as i can read write and erase.  I created a small file system on an usb disk and used HxD to read it to a .bin of the file system. I can then either use objcopy or JFlash to create a hex file with my file system placed passed the mcuboot partition.  The issue I have is that when I flash I just get 0's back and the verify fails. below is my testing.

Erase Write Read

nrfjprog  --log -f nRF53 --qspiini con_qspi.ini --qspieraseall

nrfjprog  --log -f nRF53 --qspiini con_qspi.ini --memwr 0x100f0000  --val 0xAAAA

nrfjprog  --log -f nRF53 --qspiini con_qspi.ini --memrd 0x100F0000  --n 100

I tried doing the same to my zephyr.hex from the project with the same results

Hi Edward,

Could you check that the QSPI flash memory is properly erased before writing?

nrfjprog --log -f nRF53 --qspiini con_qspi.ini --qspieraseall 

Regards,

Priyanka

I already did that it is all 0xff.  You can also see that the other bytes in the write read are 0xff

Hi Edward,

It does look puzzling. Please make sure our bin file is properly aligned, i.e. sometimes padding can help. Also, please verify that your memory layout does not overlap with any other critical regions. For further understanding, it would also be good to use a debugger t step through the initialization and programming process.
