您好,在AM335x的Linux SDK 06.03版本中提到一条勘误修正,“LCPD-13887 DDR Controller ECC Scrubbing feature can cause DRAM data corruption ”,我们有一个产品基于较早期的SDK开发的,直接替换为新SDK生产风险较大,我们想要只修正DDR ECC这一个点的问题,有这部分的详细说明么?
目前这个产品的SDK比较古老,目前官网上面已经没有这个版本,估计在2014年前后,早于当前官网SD 02.00的release,因此我也无从去确认当时的release note里面是否有这个问题,这个版本uboot版本是2013.01.01,kernel版本是3.2.0
看到e2e工程师有新的回复。
I had another look, yes, AM335x does not even support DDR-ECC as it would require special HW. The internal issue known as LCPD-13887 was assigned somehow to all of our platforms no matter if they were actually capable of DDR-ECC or not. This sometimes is done during the investigation phase to make sure we look into all possibilities before refining/narrowing the scope of an issue. Basically, in case of AM335x the issue should not have even gotten listed in the release notes.
