王工您好:
tms570进行pbist自检,完成后需要进行ram重新初始化吗?如果需要的话,需要重新初始化哪些ram?谢谢。

Hi Mingxi,
tms570进行pbist自检,完成后需要进行ram重新初始化吗?
Yes, TI recommends that the PBIST routines be executed on the SRAM prior to the auto-initialization.
如果需要的话,需要重新初始化哪些ram?
The RAM group to which you have performed the PBIST.
王工:
我看HL_sys_startup.c里面,poweron_reset后需要初始化L2RAM,来避免ECC错误。
我想问一下,如果不执行_memInit_()的话,一定会产生ECC错误吗?如果产生了,在ESM的GROUP几能监控到呢?
case POWERON_RESET:
/* Initialize L2RAM to avoid ECC errors right after power on */
_memInit_();
如果不执行_memInit_()的话,一定会产生ECC错误吗?
如果有ECC问题,一定会被检测到。
如果产生了,在ESM的GROUP几能监控到呢?
可以检测到。具体是哪个ESM group,要看情况。有可能是EPC ESM1.4, or 2.21. 你得到的是什么?
