Tool/software:
Hi Team,
I want 4 JESD links with different lane rates and trying to use use jesdSystemMode=[2,2] in my application.
as a starting point, I have changed jesdSystemMode alone in working configuration and changed sysParams.LMFSHdRx as given below

#In HSDC Pro ADC tab, Select AFE79xx_2x2RX_24410; Data Rate = 245.76M ---> To capture 4 RX channels
#In HSDC Pro ADC tab, Select AFE79xx_1x2FB_44210; Data Rate = 491.52M ---> To capture 2 FB channels

This is giving "Lanes in the JESD mode are more than supported". can you please help me with this?
Thank you,
