AFE7950EVM: Problems with design and errors when running

Part Number: AFE7950EVM
Other Parts Discussed in Thread: LMK04828, AFE7950

I have the version of latexx 2.9 and the AFE7950EVM board. When I try to run AFE.deviceBringup() i get some erros. See following image. Why is this hapenning?

Another question. I want to control the FPGA_REFCLK2* frequency in addition to the GTXCLK that is already being configured. How can I do this in Latte? The FPGA_REFCLK2 is the signal name output from LMK04828 which goes into the FMC connector.

Another question. There is a signal called SYNCBOUT** that is an output of the AFE7950. What are the conditions for this signal to activate? In my setup I am using only TX (DAC) for early testing, and the syncing process is not starting, which is related to this signal. 

 

Please advise

    Regarding the run problem I was having it seems that running the latte with admin privileges solved the problem.

    I still would like some kind of clarification on the other questions.

    Thanks

    Hi Rafael,

    With the latest version of Latte this can also be fixed by adding the lines below at the top of the script. The issue that you are facing is that without the lines given below some parameters are not being set to a default. 

    sysParams=AFE.systemParams
sysParams.__init__();sysParams.chipVersion=chipVersion

    Regards,
