Hey guys, I Have 3 cc460 MC68HC11F1 chips I am trying to read using UPA Usb v1.3. I tried using the adapter and reading from the chip on the board in circuit and also tried reading two cc460 chips outside the board both by soldering to the chips and by using the adapter. None has worked. I keep getting Reset High Error or Device Not Respond error.
For in circuit I cut trace to rx and still nothing. I removed p9 and powered up ecu externally and still nothing. I get Secured Device error when testing connection on board.
I tried to change voltage from 5v to 3v and still nothing
I bridged chip pins 1 2 3 to UPA pin 5 and still nothing
with chips outside of ecu i tried adding a 16mhz crystal for oscilator and still not working.
How can I read this chip using UPA Usb?
I know Galleto and Pa Soft. That is not what I am asking about. I want to read with UPA.
Can anyone please Help?
