Re: Bodhi Debian and SanDisk ReadyCache

This is encouraging. On a whim, I plugged the Sandisk ReadyCache into the Pogo V4 booting with stock Marvell/ALARM U-Boot, and it recognized the disk and booted without problem!

Now a little bad news. With ebbes's SATA patch for Pogo V4, the 2014.01 U-Boot does not read this disk read properly in ide reset. And with my 2014.01 patches for GoFlex Home/Net, U-Boot did not recognized the disk either.

However, once we booted into Debian, sata_mv driver does not have any problem with this disk or any other SATA drives.

Also note that this only applies to Sandisk Readycache disk. All other SATA drives have no problem with the new U-Boot.
