Crashlogs are empty/borken - TD-W8970 v1

Device TD-W8970 v1.
Lot of crashes, all does not produce anything on logs (even tried to crank up log levels and saving to USB, to be sure to read last lines logged, but no errors is shown).
After the automatic reboot I can see the message
Crashlog allocated RAM at address 0x3f00000
with logread.
No log file is generated inside
/sys/kernel/debug
.
I compiled a custom image with
/dev/mem
enabled and dumped the memory after 0x3f00000 (basically last
MB
of ram available) and I can only see the bytes “A1 EE DE AD” followed by ~1KB of “00” and after that probably other programs code.
In this thread there is the full explanation
about how this device is currently unstable, and having no logs available makes debugging x10 times harder.
