Hii,
I am working with ti-processor-sdk-linux-am57xx-evm SDK on DRA7xx-EVM . I have changed the dts file according to DRA7xx hardware.
While working with Processor SDK , dss module is successfully initialized but still i am not getting anything on the display.
When i executed modetest command i am getting like this, here the connector ids are different than DRA7xx SDK so please let me know because of that connector is he not driving anything on the display. If yes then please let me know how to change it?
