it'll be 1024 * (mult + 1). Hmm, mult isn't set for highspeed isoc
endpoints. So here you go:
Great! all the 4 patches you sent so far fix the issue on v4.4.21 tag!
Now I see 3 1024-bytes transactions in each SOF.
Great news. But the same changes still can't work in my side. I need to
look at other registers.
on your 3.18 kernel?
Yes. On my 3.18 kernel. But I am sure the trbs are same for the isoc
transfer. I am suspecting other registers now.
Do you mind dumping the dwc3 registers in your side and share to me? Thanks
in advance.
in which state you want me to 'cat regdump'? before or after run the
video capture program on the host?
I don't know whether you enabled runtime pm or not. If possible, could you
please help to capture the regdump before and after the video capture app with
runtime pm DISABLED? Thanks a lot.
I just added usbcore.autosuspend=-1 in uboot bootargs. Attached are the
regdumps before and after running video capture.
Thanks a lot for helping on this. Really appreciate it.
