error in gdb in toolchain-riscv32-esp is missing libpython2.7 on Debian bookworm and others.
Solution use the latest releases instead:
- Releases · espressif/binutils-gdb · GitHub
copy bin/riscv32-esp-elf-gcc* to .platformio/packages/toolchain-riscv32-esp/
helped, so I assume updating to the new release will do it and uses bin/riscv32-esp-elf-gcc-no-python.
