Hello I have an nrf52810 custom board and in this board SPI is not work. When I try to use e-paper with SPI, SPI MOSI and SCK pins are not working.
I also tried nrf52840 board and in this board everything works fine.

When I flash to the nrf52810 chip, I change spi1 and gpio1 to spi0 and gpio0. I also check the gpio pins for nrf52810 and pins work fine.
Thanks for your helps.
