AM2634-Q1: How to enable all ECC modules?

Will Gao

Part Number: AM2634-Q1

Hi experts,

I want to know how to enable the ECC for AM263x. From my understanding, AM263x has 3 types of ECC: one for top-level RAM (such as 2MB SRAM), another one for R5FSS TCM and cache, third one for MCAN message RAM. So if we need to enable all ECC modules, we need to manipulate the followings registers, right?

MSS_ECC_AGG_MSS.ECC_AGG_TOP_CTRL,

MSS_ECC_AGGA.ECC_AGG_R5SS0_CORE0_CTRL,

MSS_ECC_AGGB.ECC_AGG_R5SS0_CORE1_CTRL,

MSS_MCAN_ECC.MCANx_ECC_CTRL, x=0,1,2,3...

Please give comments on the above method.

Thanks & Regards,

Will

Hi Will Gao

Yes, your understanding is right, however there's a slight addition to it. ECC has the ICSS, CPSW sections also as it's end points in addition to R5F and MCAN RAM's. You can find more info from the TRM Section 13.6.5.1

Thanks

Hi Will,

Please also note that TI will provide fully fledged ECC drivers for all supported memories as part of SDL (software diagnostic libraries) so customer doesn't have to start from scratch.

The first release of SDL with ECC would be available in Sept 2022 (EA release) and 17th Oct (Std. release).

Regards,

Prasad

Hi Prasad and Kowshik,

Thanks for your help and comments! Understood and wait for the SDL. BTW, Will we release related document to introduce how to use SDL?

Thanks & Regards,

Hi Will,

It will be part of the release package, even if it's not available we can get the requried documentation from the engineers that developed the SDL.
