xrun not detecting XP SKC L2 board

[kkotha]

 I have a issue with my board.

Xrun is not detecting the device. It is showing None instead of L(0..1).

I have two boards, One is detecting and the other is not.

I have checked the Plug chain connector pins on both boards and measured as below:

Detected Board                                                                                Not Detected Board

MSEL                                     3.2V                                                                                                       3.2V

TMS                                       0                                                                                                              0

TDI                                         0                                                                                                              0

RST_N_IN                           0                                                                                                              0

DEBUG N                             3.2V                                                                                                       3.2V

TCK                                        0                                                                                                              0

TDO                                       2.8V                                                                                                       2.8V

PRSNT_MSTR_PIN          0                                                                                                              0

Is my board is broken so it is not dectected using xrun –l.

Can anyone help me out with this issue?

Thank you.

hi,  first checks would be to validate for correct power sequencing. is it possible to share the schematic?

You are able to detect one board and not the other. I think your board is broken.
