Hi Kevin,

I also work with these two boards nrf52832 and nrf52810. My code works great on the 832 board, but when I change the config and run on 810, I get some problems.

Firstly, for the spi, it can transfer once time, but have no callback, will lead the code run to somewhere like arm_startup_nrf52810.s and can not do anything. I really don't know why?

Secondly, when add the FreeRTOS system to the project, there are many errors, so I change the code in rtos, it can work now, I use a semaphore to block the task, but the task can run even thouth without a semaphore. it is very strange.

How do you solve the problems on 810, especially for SPI, please tell me.

Best regards.

Try to set NRF52810_XXAA as preprocessor symbol, and remove NRF52832_XXAA. You should also adjust the RAM/ROM sizes.
