Hi Rajesh,

Did you do functional testing of this patch on actual hardware?

Thanks

Hi Oleksandr,

Sorry about the delayed response.

Yes, I have did functional verification of this patch with our development platform which has a eMMC 5.0 controller and a 64GB eMMC disk. With this patch, our controller is enumerated and I could see the disk getting detected with boot0 (4MB), boot1(4MB), RPMB partition(4MB) and user accessible space of around 55GB. I could able to run iozone properly for basic read/write.

I am facing some issue when trying to use HS400 mode. I am working on it and have some questions. Will come back to you once have some clarity there.
