Are these both PCAT and dexter tools public?
I think, PCAT comes as part of Qcom Package Kit.
Last time, I checked with @Brian, he was saying the they use PCAT
software tool running on x86_64 machine attached to QCOM device to
get the dump(via USB) out of the device.
Dexter.exe seems private tool, that only requires if we use storage
(via ufs/emmc) to save minidump on the target device itself and later
use adb to pull out the rawdump partition dump and pass it through
dexter to convert it to same binary blobs which we got directly through
PCAT.
I don't at least have any way to avoid dexter tool at the moment.
However, i will think if we can develop any script which does the
same.
