Semihosting requires some instrumentation in order to output your printf to a PC telnet terminal. Semihosting must be enabled in the J-Link GDB-server What are the limitations using semihosting? You need a SEGGER J-Link. Semihosting is not supported by ST-Link GDBserver Cortex-M target uses breakpoints (BKPT instruction) to pause target and print messages to terminal. ARM7/ARM9 instead uses software interrupts or supervisor calls (SWI/SVC instructions). Application or interrupt code will NOT run while semihosting transfers are active. You risk losing interrupts. Timing penalties to application execution due to breakpoint/interrupt and due to instrumentation 2 Linking semihosting instrumented syscalls 1. Open the project properties tool settings, go to: C/C++ Linker Miscellaneous node and add: -specs=rdimon.specs Code will now link against semihosting instrumented syscalls 2. Remove any syscalls.c that may be part of the project since such implementation would override the linked syscalls 3 Initialize the monitor handles Initialize the semihosting monitor handles before any calls t……
