[docs] fix outdated GNU GCC toolchain link in qemu-vexpress-a9 README

2026-09-11T05:26:28Z

The link points to launchpad.net, which shut down its gcc-arm-embedded downloads years ago (the URL now returns 503), and the tarball it names is a 2016 Q3 build (gcc 5.4). - Point to Arm GNU Toolchain Downloads, matching the link already used in bsp/nxp/imx/imx91/README.md. The old gnu-rm page covers the GNU Arm Embedded Toolchain, which Arm has superseded. - Mention installing the toolchain from the distribution package manager, with Debian/Ubuntu as an example, since rtconfig.py already defaults EXEC_PATH to /usr/bin. libstdc++-arm-none-eabi-newlib is listed because LFLAGS links with -lsupc++.

[bsp/qemu-vexpress-a9] support function names in backtraces

2026-08-28T03:29:05Z

Pass -mpoke-function-name to the compiler and assembler when RT_BACKTRACE_FUNCTION_NAME is enabled for the Cortex-A9 QEMU BSP. Keep the BSP configuration opt-in so users can enable symbolized backtraces through menuconfig without changing the default build. The flag is appended through CCFLAGS and ASPPCOM after the build environment is created instead of concatenating it into CFLAGS/CXXFLAGS/ASFLAGS: when the toolchain is selected with --exec-path, PrepareBuilding() reloads rtconfig and _apply_exec_path_override() overwrites those variables, which would silently drop the option. The build still succeeds but function names are missing from the text section, leaving backtraces without usable frames. Example backtrace in QEMU (vexpress-a9, RT_BACKTRACE_FUNCTION_NAME=y, fault triggered from msh through cmd_fault -> fault_level1 -> fault_level2 -> fault_level3): backtrace: 0x600475a8 @ fault_level3 0x600475dc @ fault_level2 0x60047608 @ fault_level1 0x60047630 @ cmd_fault 0x6006ca80 @ _msh_exec_cmd 0x6006cb3c @ msh_exec 0x600717b4 @ finsh_thread_entry Signed-off-by: Hui Su <3164683437@qq.com>
