J721EXCPXEVM: Changing pixel clock for HDMI data

Brahim Salh

Dear TI experts,

I am running dss_display_test under J721E EVM. I would like to know how to change the output pixel clock when I work with HDMI interface?

with DSI, I can do it using UB941 registers but for HDMI I don't have any idea how to change the output data frequency.

Best regards,

Brahim

Brahim,

I think pixel clock for HDMI is fixed in dss_utils_j721e.c file. can you try changing it in this file and see if it works for you?

Hi Brijesh,

I tried this before and it didn't work. Now it works :)

Thank you,
