QuadMxME DS1 LED not lit

DS1 Indicates the status of the VADJ power supply coming from the FMC carrier (the VCU118 in this case). Has the VCU118 been modified in any way? Is the VCU118 powered up with the power supply that it was shipped with?

Hi Jason, thanks for replying

Actually the problem is solved. Mistake I was doing is using the ether net cable came with VCU118 which is a cross cable. So I just changed the ether net cable and it worked perfectly fine.

Hi Brinta,

Is your Quad MxFE board pressed all of the way into the FMC+ connector on the VCU118?

Do you have a 500 MHz clock applied at 1-2 dBm to the Quad MxFE before powering on either Quad MxFE or VCU118?

I would recommend communicating with the VCU118 over JTAG (COM port) and using the commands 'iio_attr -d' and 'iio_info' to verify the VCU118 is "seeing" the Quad MxFE, more information can be found here on those commands:

I would also recommend verifying that the JESD lanes are working correctly using the same COM port with the command "jesd_status", more information can be found here:
