TDA4VH RTOS about eDP driver question

Hi xu ji,

2 lanes output is not really validated & supported, so recommendation is to use 4 lane mode only.

could it support on RTOS driver?does it difficult to adapt？

No, its not even supported in RTOS driver. I would suggest keeping 4 lane mode or whatever supported in SDK only.

ok,if we up to 4lanes and we used serdes4 bus for DP on SOC,where need changed to set this resource in RTOS driver?

Thanks

Hi xu ji,

Sorry did not get it. If you are planning to use 4-lanes DP, no change required in the RTOS driver or SERDES configuration, because this is what is supported by default in the SDK.

I not ask the evm board,I ask it is our custom board design,now serdes0 used for USB in Linux RTOS will effect Linux boot because resource conflict,if we comment DP in RTOS then Linux will boot success,so DP resource need changed to serdes4 bus,so I ask it.

sorry for my wrong，evm board used serdes4 same with our board about DP，the issue is our board use two lanes for USB,so we want to delete the two lanes setting on RTOS,so ask where config DP lanes resource on RTOS?
