Search through `dmesg` output, look for BERT related messages and try to save the BERT content as both .hex and binary files.

get-bert.sh

#!/bin/bash

NOW=$(date +%s)
HEXFNAME=bert-data-${NOW}.hex
BINFNAME=bert-data-${NOW}.bin

{ dmesg \
| grep '\[Hardware Error]: \+[0-9]' \
| sed -r '/.*/ {s/^.*\[Hardware Error]: +[0-9a-FA-F]{4}([0-9a-FA-F]{4}): (([0-9a-FA-F]{8} ){4}).*$/:10 \1 00 \2 00/;s/ //g}' \
; echo ':00000001FF'; \
} | srec_cat - -intel -IGnore_Checksums -o - -intel > $HEXFNAME

objcopy --input-target=ihex --output-target=binary $HEXFNAME $BINFNAME
