Hi I am very new to RIOT, and I don't yet know my way around the code, so sorry if this is an easy question.
I am trying to create a platform based on the samd21 that has no UART for stdio. Unfortunately its seems a uart stdio is pretty much assumed through a lot of the code. What is the cleanest way to prevent things like uart_stdio_init from being invoked by newlib/syscalls.c::_init() ? There must be some kind of mechanism because I don't think the native platform takes that code path. I might later add stdio based on an in-memory array manipulated over JTAG (like SEGGER RTT), but I am not sure which layer to add this in as. Any suggestions? Thanks Michael
