In my case, JPEG driver doesn't know how much data to transfer. So i have to send zero from there. Also, i am not sure why would peripheral needs to be flow controller if the peripherals driver already know how much to transfer? > > (Ok, it already only supports one SG entry, but that's something else > which needs fixing - which may be possible now that you've cleaned up > the LLI creation code.) > . Yes. I cleaned it up. -- viresh
