Q2686 Boot Mode problem


#1

Hello All.
I have Q2868 that enters endless reset loop when powered on.
It is for sure OAT application error, so it isnt possible to stop it by AT+WOPEN. The problem is that i cant connect to target by DwlWIN when BOOT pin is tied to 1.8V.
When BOOT pin connected to 1.8V, Q2686 sends hex string 81 81 81 FF, and then continues normal booting.
Is this string is OK?
Firmware is R72 (upgraded recently).
I have tried all versions of DwlWIN without success.
How can i restore CPU to normal work?
Another question - documentation says that SafeBoot is activated by default.
Maybe i will better try to do Safe Boot?

Thanks All.
