Using TinyCLR device to program a slave microcontroller

Has anyone used a TinyCLR device as a master controller to a slave microcontroller and pushed firmware updates down to the slave? Need to use a small microcontroller for real-time processes but I need to be able to do in-field updates to the slave.

Any suggestions?

I would suggest a bootloader on the microcontroller and use UART, SPI etc. to transfer the application. I don’t think the TinyCLR expose a JTAG or other ICSP interfaces.

I have done that programming a STM32L4 via SPI. Just make sure your processor’s bootloader supports SPI/UART programming.
