Mbed-os: FPGA CI shield kills serial output during serial test

Created on 9 Jul 2019 · 2Comments · Source: ARMmbed/mbed-os

Description

The UART testing (and potentially SPI if a target uses combined UART/SPI peripherals, such as EFM32) lacks a guard against trying to test the same UART peripheral as the one which is driving the communication with the host (to feed back the test results).

I think you'd want to introduce something like pinmap_restricted_peripherals, which guards against reconfiguring test-system-critical peripherals, such as the GreenTea communication channel, or the RTOS timebase.
