Is there a jumper setting for this?
You don't have to disable OpenSDA at all.
Simply connect the JTAG connector.
Thanks Daniel. I did, I connected a Lauterbach ICD and as soon as i do that the 3.3V and 5V is pulled down. Perhaps something wrong with the ICD or connector. I did notice on page 5 of the schematics (in really small font) that a trace has to be cut to isolate the MCU from the opensda. I can also try connecting another ICD and see what happens.
I don't have any problem programming the board with Lauterbach.
Lauterbach connected to J10.
Powered from SBC, J8.1-2.
Do you have only one board?
