# This script can be used to decode the backtrace that's dumped on assertions.
|
||
|
|
#
|
||
|
|
# On assertions we can find the raw backtrace dump similar to:
|
||
|
|
# ...
|
||
|
|
# xtensa_btdump: Backtrace0: 400d3ed7:3ffb1300
|
||
|
|
# xtensa_btdump: Backtrace1: 400d3f33:3ffb1320
|
||
|
|
# xtensa_btdump: Backtrace2: 400d2875:3ffb1340
|
||
|
|
# xtensa_btdump: BACKTRACE CONTINUES...
|
||
|
|
# ...
|
||
|
|
#
|
||
|
|
# Copy that to a file and call this script as:
|
||
|
|
# ./tools/esp32/btdecode.sh backtrace_file
|
||
|
|
#
|
||
|
|
# The result should be similar to the following:
|
||
|
|
# 0x400d3ed7: xtensa_assert at xtensa_assert.c:108
|
||
|
|
# 0x400d3f33: up_assert at xtensa_assert.c:184 (discriminator 2)
