SK-AM62: Change the Flash Boot Mode from Octal SPI to 1S-1S-1S mode

SK-AM62: Check and change the SPI bus and Flash chip to default mode after Flash Operations in Uboot

Hi Team,

I have already raised a query : SK-AM62: Change the Flash Boot Mode from Octal SPI to 1S-1S-1S mode - Processors forum - Processors - TI E2E support forums

But have not been getting response further, hence raising a new query.

I have AM62x Evaluation board with S28HS512T Flash Chip. Our VxWorks image supports the 2023.04 version and 2021.01 versions of the Uboot only.

Here, the vxworks flash driver is not attaching as it is unable to communicate/ transter messages to the flash chip if the uboot access the flash. When the flash is not accessed in Uboot for any operations like read/write etc, then the VxWorks flash driver is attaching successfully. 

We require the flash chip and the flash controller to be reset to the default mode i.e 1s-1s-1s mode. How can we ensure that and how can we debug this further from the uboot perspective?

Note: Please refer the link attached above for the detailed process and commands that we have followed.

Thanks and Regards,

Hamsa L
