Hi all!
I have a custom board with an nRF52840 and an SX1262. They communicate via SPI. When I use CONFIG_SPI=y, I get the following error when the board turns on:
<err> qspi_nor: JEDEC id [00 00 00] expect [c2 28 17]
This is my prj.conf:

I have seen other issues related to this error on the Q&A but it seems that it's usually thrown when you try to interact with the flash via SPI, but it's not my case because I get the error upon initialization, without trying to directly use the SPI. My questions are:
- When do I have to worry about this error?
- How can I find out the origin of the error and solve it?
Thanks in advance.
