I am new to RT-Thread, when I built the project in the directory of rt-thread-master/bsp/gd32450z-eval/ with keil_v5, then Keil_v5 outputted the following:
"no source": Error: #5: cannot open source input file "....libcpuarmcommonbacktrace.c": No such file or directory
So where to find backtrace.c, what is it used for ?
Finding the right resources like backtrace.c can be tricky. I once faced a similar issue when trying to debug an RTOS project and found that community forums were invaluable for sharing insights. @escape road, Have you tried exploring the documentation further? It may provide some clues!
