TMS320F28377S: CLA data ROM check

Chrisjs

Hi,

As a part of safety / diagnostics i need to test the following.

1. How to test CPU1.CLA1 data ROM ? How can i check the CRC of the same? Is there an example available. I have not seen much details about CLA data ROM in TRM.

2. How can we test CLA message RAMs and shared memories?

Thank you

Hi,

1. To do this you will need to read the CLA Data ROM from the CLA and compute some sort of CRC or checksum.

2a. First, the message RAMs and shared RAMs have parity.

2b. Second, if you wan to test the RAMs, you can do a couple things. You can use a CRC for static data. Or you can use the CPU MBIST, which is a RAM test done by the C28 on RAM memories. Please see this AR for more details: www.ti.com/.../spracb9.pdf

Hope this helps,
sal
