I am using TC387 target. 

1. I need to access MCi_ECCS [i = 0-95] for CPU0 DSRAM. I want to know which register index I need to select to access CPU0 DSRAM(I am looking for i value for CPU0 DSRAM). 

I was looking for where I can find this mapping in the user manual, I could not get much out of it. (On-Chip System Connectivity chapter in the usermanual. )

Can some one pls help me to identify correct register index. 

2. I am trying to generate ECC for the testing purpose, in the normal software running state.

     I am trying to access ECCMAP bits to achieve this.

pls let me know if we have an easy wat to generate ECC error [for testing purpose] for SRAM.

Hello Dev_07

1. you can find SSH instances ID in TC38x_appx_um_v2.0.pdf. 

2. I think setting the test you want is very difficult... 

But, why did you want to make this test? is its purpose to check SMU alarm for ECC? 

As I know, Infineon does not recommend this type of test. 

in my case, I and my team had reviewed only, not tested SMU alarm config.

Hi,

Thank you for the reply. 

I am trying to write test software for ECC detection/correction. 

So i am trying to generate ECC error for SRAM & check if a particular alarm is reported. This is ECC error injection for testing purpose. 

From above table[in your post], can I conclude that for CPU0 DSRAM I need to use MC0 ? 

thanks.

Hi Dev_07

um.. what is DSRAM? Do you mean DMEM? 

in the SSH list, There is no DSRAM.

Hi,

DS RAM is CPU data scram pad RAM. As you mentioned  It should be DMEM. 

thanks.
