DRA744: USB Eye improvement : TERMINATION_CONTROL.RTERM_RMX reading variable

Peter Li79

Part Number: DRA744

Hi:

According to below guideline, the TERMINATION_CONTROL.RTERM_RMX should be constant when being read after set '0' to TERMINATION_CONTROL.MEM_FS_CODE_SEL.

But in one of our customer's board, the reading is variable. Is there any mis-understanding? Is the variable expected?

Many thanks.

Does this happen on multiple boards or only 1 board? Also can you let me know what value you read back from your OCP2SCP_TIMING register?

Hi Peter,

We haven't heard back from you, I'm assuming you were able to resolve your issue.
If not, just post a reply below (or create a new thread if the thread has locked due to time-out).

Regards,
Yordan
