MCUboot on the Thingy91

[John_Turner]

I'm trying to duplicate the boot behavior of a Thingy91 on a custom board, i.e. SW4:BOOT and SW3:BUTTON on power up, but the switches available use different IO. I'm wondering where and how to modify the configuration.

Thanks,

Hi Ted,

I'm really just beginning to work with Zephyr but I am developing an appreciation for it's flexibility. The video (Marti Bolivar) was quite helpful and the specific segment on I2C/SPI was a bit of a watershed moment for understanding the philosophy behind the approach. My board uses an SPI device that's also on the THINGY91 so now I'm looking forward to bringing up instead of dreading it.

On MCUBoot; Originally, I was expecting to find a unique device tree file for MCUBoot but since it's meant to be independent of the operating system having some other form of hardware definition is understandable. One thing I thought might have been configurable specifically for MCUBoot would be the UART but it does take that definition from the DTS file for the board.
