Hi @JColvin
Thanks for your reply
The voltage at different caps are as follows
C291 - 12.08V
C293 - 3.3V
C271 - 5.02V
C277 - 1.00V
C302 - 0V
C264 - 12V
C303 - 0V
C296 - 1.2V
There is no visible physical damage to any ICs. None of the status LEDs are on. The peripherals attached to the system were Zmod ADC 1410 on ZMODA, and one serial LCD on the PMOD connected through flying wires.
It looks like that IC29 has somehow locked every thing, but I can not find any datasheet of it.
Thanks
