DS90UB928Q-Q1: How we can use 928 pair with 947

Part Number: DS90UB928Q-Q1

Hi team,

Our team used the 948 pair with 947 ago, now we want to use 928 pair with 947. I downloaded the 948's firmware(a mcu's firmware) into 928 board directly, the TFT panel(928) could not be lit up.

But if I used a 948 board connect with the host(947) first, then plug out the 948 board and plug the 928 board into host, the TFT panel(928) was lit up.

I not sure this issue caused by 947 or 928, can you give me some suggestion?

Best Regards.

Could you expand on this? Are the 948 and 928 both on EVM boards?

The 928 and 948 have different limitations for FPD-Link III speeds. Has this already been accounted for? If not, an adjustment on the 947 would be necessary.

Hi Jack,

The 948 and 928 are build in different EVM board, we will recheck the 947, thank you very much.
