Hello

[quote user=""]/home/henry/ncs/toolchains/v2.3.0/opt/zephyr-sdk/arm-zephyr-eabi/bin/../lib/gcc/arm-zephyr-eabi/12.1.0/../../../../arm-zephyr-eabi/bin/ld.bfd: app/libapp.a(flash_nor.c.obj):(.rodata.spi_nor_config_0+0x0): undefined reference to `__device_dts_ord_91'[/quote]

This sort of error usually means something is wrong with your devicetree. Since you seem to be using a custom board I would assume the error could come from your board definition.

You can have a look at the generated devicetree in build/zephyr/zephyr.dts to see if anything isn't as expected. The error mentions flash_nor.c and spi_nor_config, so anything related to flash or spi would be a good place to start.

../src/flash_nor.c: In function 'spi_nor_process_sfdp':
../src/flash_nor.c:1031:16: warning: 'rc' is used uninitialized [-Wuninitialized]
1031 | return rc;
| ^~
../src/flash_nor.c:958:13: note: 'rc' was declared here
958 | int rc;
| ^~

Looks like specifically what happens with rc in flash_nor.c would be a good place to start.

Best regards,

Einar
