Solved, Bad MCU???

Have a version six that says SI570 not found.
Replaced 570, and U10 same result.
Checked with scope and can trace signal from SI570 all the way to the mcu pins 92,93
All looks good. Could the MCU be faulty??

I tried another UI Board and it works just fine, so the problem IS in the UI Board.
Re-loaded bootloader and firmware, but no change.
next step is to replace MCU.
Out of ideas!!
Thanks. de Chuck

Found bad solder at another pin, not sure why that caused the error, but it works now!
Thanks, Chuck
