Hi,
do not worry, I'm sure that MCU is alive. I do not see commands in the
log however (use -d3 next time)
I guess the flash is erased and watchdog keeps resetting the MCU.
You can check RESET pin that MCU generates low pulses.
Set
reset_config srst_only
and try and if needed retry several times
reset halt
If it does not work, check if reset signal is driven by debugger.
Big surprise that chip uses new SDID form. Can you send output of
mdw 0x40048024
Unfortunately there are at least two different flash configs for K22 and
REVID should
be tested to select correct one.
