Heinz Junkes commented: https://gitlab.rtems.org/rtems/rtos/rtems/-/merge_requests/494#note_123156 Hello Jacob, thank you for your quick reply. I run the whole thing in qemu. I blob the FDT from this version 1.20200601: ``` git clone -b '1.20200601' --single-branch --depth 1 https://github.com/raspberrypi/firmware.git ``` I can find the symbol in my exe file: ``` junkes@Mac BHT_VE % grep arm_pl011_read_polled examples/./build/arm-rtems7-raspberrypi2/posix_api/hpj_example/hpj_example.exe Binary file examples/./build/arm-rtems7-raspberrypi2/posix_api/hpj_example/hpj_example.exe matches ``` Das exe file mache ich zum img file um den qemu damit zu laden: ``` ./rtems/7/bin/arm-rtems7-objcopy -O binary examples/build/arm-rtems7-raspberrypi2/posix_api/hpj_example/hpj_example.exe hpj_example.img ``` and start the qemu: ``` qemu-system-arm -M raspi2b -m 1G -kernel hpj_example.img -serial mon:stdio -nographic -no-reboot -dtb bcm2709-rpi-2-b.dtb -S -s ``` Und dann starte ich den debugger mit: ``` ./rtems/7/bin/arm-rtems7-gdb examples/./build/arm-rtems7-raspberrypi2/posix_api/hpj_example/hpj_example.exe GNU gdb (GDB) 16.2 Copyright (C) 2024 Free Software Foundation, Inc.
