SPIM not Calling Specified EVT Handler Upon Completion

I am suffering from the spim problem of nRF52811.

Does this bug show the same symptoms on the nRF52811 chip?

Ok. I got bit by the SDK bug where nrfx_irqs_nrf52810.h defined SPIM1 as the IRQ instead of SPIM0 (https://devzone.nordicsemi.com/f/nordic-q-a/35145/crashing-during-the-spi-transfer-on-nrf52810/135175#135175).

I did NOT need to set NRFX_SPI_ENABLE to 1 (I think this is only valid for the non-nRF52810 variants which have multiple SPI interfaces). Fixing the SDK bug, my code worked as originally written.

Thanks.

Setting NRFX_SPI_ENABLE to 1 didn't work. Still stuck with the default handler...

NRFX_PRS_ENABLED is set to 0. I assume that I do not need PRS to use both TWIM0 and SPIM0?

SPI_ENABLED opens up a whole can of worms. I suspect that this is actually for the legacy drivers, although I am trying to use the NRFX drivers as recommended (even though there are absolutely no examples that use the NRFX interface (they all use the nrf_drv interface which makes using NRFX given the terse documentation extremely difficult)). SPI_ENABLED goes through apply_old_config.h which I think tries to do some translations to back to legacy drivers.

It does look like I may have to set NRFX_SPI_ENABLE to 1 in order for the IRQs to be compiled into the project. The problem is that when I do so, it includes nrf_spi.h (via nrfx_spi.c) which includes a lot of NRF_SPI_* #defines that are present in the include files for the NRF52832 variants, but not those for the NRF52810 which only includes the NRF_SPIM_* form. In short, the nrf52.h files include both NRF_SPI_* and NRF_SPIM_* #defines whereas the nrf52810.h files only have the NRF_SPIM_* forms. nrfx_spi.c requires the NRF_SPI_* form, so my code won't compile yet.

Right now I am going through and adding the missing definitions found in the nrf52 files into the associated nrf52810 files. I do not know if this is appropriate, but I guess I'll find out when done.

Hi,

I suspect that you're going into the default_handler due to the interrupt vector not being compiled in.

Do you have sdk_config.h::SPI_ENABLED defined to '1'?

It could also be that the peripheral sharing module nrfx_prs is enabled in your sdk_config.h (NRFX_PRS_ENABLED), but not included in the project. If this is the case, then set NRFX_PRS_ENABLED 0.

Best regards,

Håkon
