I would recommend you to post a new ticket where you describe your exact setup and issue, instead of resurrecting this 3 year old resolved ticket. You can reference this ticket and say you have a similar issue, but if the solution described here is not working for you, the issue is most likely not exactly the same.

Hello,

Sorry but AlexisS doesn't have an account anymore on the forum. I am the one receiving the notifications from his account and I don't know how I can help you with that issue.

Best

alexisS I have an identical situation here. On our custom board we have MX25R6435F connected on different pins to nrf52840. We are able to read the manufacturer and device ID ok using the appropriate custom instruction via the firmware but can't read/write/erase. Using nrfjprog, everytime we run --qspieraseall, the Erase command seems to execute almost immediately (as opposed to minutes for the PDK); a subsequent --readqspi simply dumps 0x888.... Can you explain exactly how you fixed this problem?

Great, thank you for reporting back the solution.

Well removing extra wires to the logic analyser solved the problem...

Thanks for your time.

Can you provide schematics of your board? Are you running any applications on the board, or did you erase it prior to writing QSPI? Is the CSN pin shown in your images? Could you please mark the pins on the image? Do you have similar logic traces for the DK where the communication works?

of course; like I said previously it's the default one with just some pin changing to match my design

Can you post the QspiDefault.ini file that you used?

Thanks for your reply,

Yes I can program the board, moreover I have a working QSPI driver (so the connection isn't involved)

Hi,

Are you able to program the board using nrfjprog?

Could you provide the log file from nrfjprog (add the parameter --log and provide file log.log)? Please also upload scematics for your board.

Best regards,
Jørgen
