# This little script allows you to get an approximate stack backtrace when Espruino crashes
|
|
# and prints the crash info to the debug console. It looks something like this:
|
|
# 37608> Stack:
|
|
# 37609> 3ffff9d0: 3ffff9f0 00000000 00000001 40201837
|
|
# 37614> 3ffff9e0: 000783b7 00000000 3fff2a48 40212e62
|
|
# 37619> 3ffff9f0: 3ffece2c 00000000 00000000 4020193e
|
|
# 37624> 3ffffa00: 3fff29c8 3fff1714 3fff29a8 3fff1714
|
|
# ...
|
|
# 38072> 3fffff90: 00001000 00000002 00000000 00000000
|
|
# 38077> 3fffffa0: 000002a1 00000000 00074f20 40100000
|
|
# In such a case, run the script (possibly after editing the path below) and at the prompt paste
|
|
# the entire stack dump. You will see something like:

# You need to set DEBUG=1 when building in order to see the files and line numbers, if you don't
|

# you'll just get the function names, which is often sufficient...
|
|
|
|
# WARNING: this script doesn't parse the stack dump, it simply extracts all memory words that
|
|
# contain an address that lies in program memory and prints those. Thus there may be a few extra
|
|
# lines if a pointer to code happens to be on the stack. You need to apply a tad of judgement...
