Target: M4, SoC iMX7D
V6.34b I can get the target hard locked followed by JLink resetting entire SoC ..
Exact steps I'm not sure of, but it's single stepping a piece of code.
When stepping, suddenly I get many cannot access memory ... errors. After which I have to kill my JLinkGDBServer.
A subsequent attempt to re-connect to target leads to JLinExe or GDBServer giving error:
****** Error: Bad JTAG communication: Write to IR: Expected 0x1, got 0xf (TAP Command : 10) @ Off 0x5.
Could not find core in Coresight setup
..
This is followed then by full SoC reset (duuh!!), while JLinkExe exits with :
Cannot connect to target.
Immediate re-connect attempt after SoC reset works, but .. This is annoying as my whole system is dead and need full reboot of cores.
