NRF9160 Disabling UART for BOOTLOADER_MCUBOOT

[GJSea]

Hi,

I have an SPI peripheral on pins 26, 27, 28, 29 which I'm able to override the default system's UART0 pin assignments in nrf9160_pca10090ns.overlay. However when I enable CONFIG_BOOTLOADER_MCUBOOT I suspect it is somewhere grabbing those pins for itself and knocking out my SPI peripheral again.

Where does one disable the UART or reassign its pins for BOOTLOADER_MCUBOOT?

Thanks!

Hi GjSea,

• (recommended) Please add an nrf9160_pca10090.overlay file with your pin assignments in the folder ncs/mcuboot/zephyr/

• Or you could change the nrf9160_pca10090_common.dts file

Thanks! Modifying nrf9160_pca10090_common.dts with my uart0 pin reassignments fixed the issue.
