This page covers migration information for applications built on top of the Processor SDK Linux AM62X.
2.3.1. Processor SDK Linux AM62X 08.xx Releases¶
126.96.36.199. Processor SDK 08.03¶
- This is the first release of Processor SDK Linux AM62X.
2.3.2. AM62 SD UHS Speed modes Enable¶
In 08.03 release, SD card enumeration failures were observed on a few U1 class of SD cards. These include but not limited to,

- Kingston U1 class cards
- HP U1 class cards
A conservative approach was taken to disable UHS modes by default, and support wide range of SD cards. However if required they can be enabled by using the following steps,
