After configuration of XADC wizard 3.3 in FPGA part of xc7z020clg484-1, generating XSA file and adding it to petalinux:
1. In channel sequencer continuous mode we are using 12 aux inputs and Vp_Vn, all of them showed the same value in raw - 3553 and real input voltage doesn't influence on it.
2. After some manipulations (trying different modes and changing inputs) and then returning all values back, the kernel stopped to boot at all. It always crashes in probe function of XADC driver (see attachments, system.txt is device tree part). And we are not able to make it run again.
