I've enabled the XAdcPs in my FSBL in order to read a value at startup. On power up, the value reads ok. However, on a soft reboot from linux, the XAdcPs_SelfTest function fails - the readback of the test value is 0x00 rather than 0x55.
As far as I can tell, the XAdc is not enabled in my linux build. I've tried with and without the PL being programmed at the point of reboot.
This is on a ZC702. The code sequence in the FSBL is...
Can anyone suggest what might be causing the failure on reboot?
