SPI Kconfig.nrfx changes in recent (1.13.99) clone - setting GPIO pins for SPI master now fails.
cpmcparland@...
My zephyr app, built on ver 1.13.0 with the following prj.cfg file:
CONFIG_FLOAT=y CONFIG_FP_SHARING=y CONFIG_NEWLIB_LIBC=y CONFIG_HEAP_MEM_POOL_SIZE=16384 CONFIG_GPIO=y CONFIG_SPI=y CONFIG_SPI_0=y CONFIG_SPI_ASYNC=y CONFIG_SPI_0_NAME="SPI_0" CONFIG_SPI_0_OP_MODES=1 CONFIG_SPI_0_IRQ_PRI=0 CONFIG_SPI_NRFX=y CONFIG_SPI_0_NRF_SPIM=y CONFIG_SPI_0_NRF_SCK_PIN=28 CONFIG_SPI_0_NRF_MOSI_PIN=29 CONFIG_SPI_0_NRF_MISO_PIN=30 CONFIG_SPI_0_NRF_ORC=0xf built and ran successfully on a nrf52840_pca10056 board. I have recently updated to ver 1.13.99 and it no longer gets through cmake because several symbols are no longer in the Kconfig.nrfx file for the SPI driver. Namely, CONFIG_SPI_0_SCK_PIN, _MOSI_PIN, and _MISO_PIN. I need to set these pins to coincide with target hardware, Also, SPI_0_NAME seems to have disappeared. Looking more closely at the Kconfig.nrfx files from both clones, the latest version has changed and does not include symbols to set up these pins. I guess I could edit the .config file, but that would be overwritten every time I run cmake. Maybe I'm just out of phase here. Is there a nrf spim driver update in progress? Any help would be appreciated. Thanks, Chuck |

Hi Chuck, SPI config has switched to devicetree and you only need following configs in you prj.conf file for SPI_0: CONFIG_SPI=y CONFIG_SPI_0=y CONFIG_SPI_NRFX=y All other configurations come from the boards DTS files. Have a look at boards/arm/nrf52840_pca10059/nrf52840_pca10059.dts and dts/arm/nordic/nrf52840.dtsi . In case you need to adapt the default settings you can add an overlay to your project directory. For more info on overlays see https://docs.zephyrproject.org/latest/application/application.html#application-dt .

Jan,
Thanks....am working on an overlay now. Sure makes the prj.cfg look a lot cleaner. Am I right to expect that this sort of transformation will make its way into other drivers as well (e.g. I2C)? Regards, Chuck |

Hi Chuck, As far as I know a lot of progress is ongoing in Zephyr to move to DTS and if I'm not mistaken I2C was there before SPI. Regards, Jan On Mon, Oct 22, 2018 at 10:23 PM <cpmcparland@...> wrote: Jan, |
