ncs 2.7.0 SPI nor flash build error

[hugh512]

I got below build error:, actually I referred C:\ncs\v2.7.0\zephyr\samples\drivers\jesd216; my externl SPI NOR flash is p25q32h and my target is to build a file system such as fatfs on the flash. I also checked the sample under  C:\ncs\v2.7.0\zephyr\samples\drivers\spi_flash\boards and set CONFIG_NORDIC_QSPI_NOR, it has the same build exception.

Hi Hugh,

Just letting you know I have started looking into this. My first guess is that something like below is missing from the main.c::main() function:

const struct device *flash_dev = DEVICE_DT_GET(DT_NODELABEL(p25q32h)); 

Please let me know if the above does not work, and I will look deeper into this tomorrow. Check out this in the meantime:  Troubleshooting undefined reference to __device_dts_ord_<N>.

It doesn't work, I put the code in main() function.according to the error, it has relation with libdrivers__flash & spi_nor

Thank you for giving it a try. I think we need to look for something else.

Which board are you building for? building for nrf52dk you will need to set both pinctrl names:

pinctrl-names = "default", "sleep";

Check zephyr\boards\nordic\nrf52dk\nrf52dk_nrf52832-pinctrl.dtsi for an example showing how to set both default and sleep.

Hi helsing: I got the same exception.

If you are building for one of the Nordic boards then it would be better to use some other names than the ones that are already there. Try using for example 'custom_spi_default' instead of 'spi_default'.
