nr52832 + nRF Connect 1.8.0 + External Flash

[embeddedER]

Hello Team,

We are interfacing nRF52832 with an external flash for data storage. Could you please point to the right document/link/code reference on how to interface external flash (on SPI) with nRF52832 on nRF Connect SDK 1.8.0?

Thanks!

Hi Hakon,

I think changing to NRF_SPIM should resolve the problem but by changing that I am facing linking error:

ncs\v1.8.0\zephyr\drivers\flash\spi_nor.c:1230: undefined reference to `__device_dts_ord_68'

I believe I need to change the prj.conf as well for this, but not sure with what. This is what I've right now and works for NRF_SPI:

#for SPI

CONFIG_SPI=y

CONFIG_FLASH=y

CONFIG_SPI_NOR=y

CONFIG_SPI_NOR_FLASH_LAYOUT_PAGE_SIZE=4096

Thanks!

Hi,

 

It should map this to the underlying driver that is used.

Did you delete the build folder and regenerate the project? It might not be that the build system was able to catch the change in the .overlay file.

 

Kind regards,
