Hi all,

Does anyone has successfully implemented Suspend to RAM feature on MIPS32R2? How can I restart kernel after putting system to sleep?

Thanks

We did that on the DB1200 board.

Your bootloader should support this. U-Boot does, at least for the Alchemy CPU.
Look for the mails from the Rodolfo Giometti. He posted patches to this mailing list and to the U-Boot mailing list to support resume for the au1x00 CPU.

Look here:

however keep in mind that some patches are now obsolete...

Ciao,
