yes - but offset 0x00-0xff is explicitly reserved regarding to the manual.
Don't know whether it is a "should not" or "must not be touched".
?
All I can see is a CPU hang with arbiter event register reporting a timeout on
0xe0023000.
?
? Check to see whether there is an invalid USB clock setting in the SCCR??
All clocks are turned on except SEC and 2nd TSEC.
?
After all USB is running fine with this patch, i.e. there can hardly be a
missing clock.
Please re-think you NAK.
