AM625: SDK 8.06 eMMC HS200 stability issue

Ethan Tian

Part Number: AM625

Hi experts

This link:https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1270184/processor-sdk-am62x-emmc-transition-issue/4853573 said there are many improvements in SDK9.2 about eMMC HS200 stability.

Customer is using SDK 8.06,because SDK 8.06 has different kernel version with SDK 9.02, could you please provide a patch to solve this issue?

The customer is about to go into mass production and cannot switch the SDK version.

Hi Ethan,

The improvement added in SDK9.2 is not just one patch on top of SDK9.1, plus the SDK8.6 kernel (v5.10) has big difference from SDK9.1 kernel (v6.1). So it i s not trivial to back port the eMMC improvement from SDK9.2 to SDK8.6. (I actually tried this about a month ago, but eventually failed in manually picking the kernel patches.)
