Trouble entering debug on KV10Z32

Hi All,


I am having no luck getting my multilink universal to connect to my custom board for the MKV10Z32VFM7. I can write the program to flash no problem and then when I cycle power, the code will run. The problem is when I try to run it in debug. It will flash the program and then lose the connection immediately after reset.


I also have the tower board for the MKV10Z32, which has the same part in a different package on it. Using my same project, if I change the processor expert CPU and pin settings over to this package, I can debug this board using the multilink as I would expect.


I have compared the debug circuit on my board with the tower board, and it appears to be the same. 10K pullup on SWDIO, nothing on SWCLK, 10K pullup on reset... is there something I am missing?


Thanks in advance,
