DS90UB954-Q1: It should reset 954 when some errors happen.

Hello Yue,

can you send me the register dump from the 954 at the beginning of transmission and after it stops working, and one more time after resetting it?

Hi Hamzeh，

Sorry to reply you late.

The set of 954 is shown below

When the access can't work,we read 0x4d ,the value always changes,maybe 0xed\0x45\0x4d.

And I found that 0x7B maybe 0xff on a large probability.Is the count full so that 954 doesn't work?

I am looking forward to your reply

   Register 7B going to ff is an effect, not a cause. Register 7B basically counts CSI errors. CSI errors seem to be happening due to something else . Same with Reg0x4D, basically it is showing that you are seeing link errors. Do you have access TI ALP tool kit? Can you run diagnostics , MAP tool? It is in 954 product folder on how you can run this

Thanks

Vijay

Hi Vijay,

The error I met is on our board we made by ourselves, not on the FPD-LINK III .So I can't use the ALP to debug.

The only way I can do is to read the registers one by one，is there any other ways?

I am looking forward to your reply .Thank you so much.
