iMX6DQ SATA BIST - Incorrect Test Patterns Generated

alanaustin — Tue, 28 Jun 2016 09:55:34 GMT

Dear Sirs.

I have a question about SATA BIST testing. (Reference Manual Section 53.3.5.13)

We wish to transmit Built In Self Test (BIST) patterns contained in the PHY controller

We are trying to generate the following test patterns

High Frequency Test Pattern (HFTP)

Lone Bit Pattern (LBP)

We are writing to register SATA_BISTCR

We selecting the test pattern using the [PATTERN] field, and initiating transmision by setting bit [TXO]

Setting bit [TXO] does initiate transmission. Unfortunately the test pattern data appears to be incorrect.

It appears to be more or less random data rather than the test patterns above..

Any help appreciated
