mxfe board doesnt show up post Stingray board is connected in iio_info iio:devices

Thread Summary

The user encountered issues with the AD9081 MxFE board not being recognized after connecting the XUD1a board to the ZCU102. The problem was resolved by replacing resistor R1M with a 220 Ω resistor and using a newer 2023_r2 Linux kernel. The user is now able to see the AD9081 device and perform basic RX/TX tests with the interposer board connected.

I have recently started working on setting up the Stingray platform on the ZCU102 board.

i followed up : https://wiki.analog.com/resources/eval/user-guides/x-band-platform hardware and software page.

ZCU102 is booting. USB to UART Bridge is working fine. I am able to SSH from another laptop over Ethernet as well.

Implemented the ADAR1000EVAL1Z Power Sequence. 

When i had connected the XUD1a board over the second slot on the ZCU platform - the mxfe stopped lighting up on the boot.

after i performed  ADXUD1AEBZ Interposer FMC EEPROM Programming, the MxFE board (ad9081) started powering on however, where I do  "iio_info" - i can no longer see the ad9081 board. even with "iio_attr -D command" - it throw cant not find device.

i have attached 3 images - one just with AD9081 board to show that it shows up in iio_info. Then i plugged in Stingray - it doesn't show up. i finally conencted XUD1a also - it doesnt show up.
