When developing for microcontrollers and for example my leds aren't working, I like to define a place in memory where I write values to depending on the place in code. Then just read out that memory address with OpenOCD (jtag of swd). #define debugVar ((uint32_t *) 0x10007000) *debugVar = 1; *debugVar = 2; *debugVar = 0xdeadcafe;
