esp-backtrace - backtrace for ESP32 bare-metal
Supports the ESP32, ESP32-C2/C3/C5/C6, ESP32-H2, and ESP32-S2/S3. Optional panic handler is included, which can be enabled via its respective feature.
Please note that when targeting a RISC-V device, you need to force frame pointers (i.e. "-C", "force-frame-pointers", in your .cargo/config.toml); this is not required for Xtensa.
You can get an array of backtrace addresses (currently limited to 10) via arch::backtrace() if
you want to create a backtrace yourself (i.e. not using the panic handler).
When using the panic handler make sure to include use esp_backtrace as _;.
