I'd like to be able to debug my FreeRTOS app running on a K22, but the connectivity of the K22 is such that the JTAG/SWD are not available. However, a UART is available, so the hope was that a gdbserver could be compiled into the FreeRTOS app and activated with a specific UART sequence, in order to set breakpoints, inspect variables, etc. Does something like this exist for the ARM Cortex M4 that runs on the K22?
