Hi
I just activated the dcache on our jadecpu board but it seems to me that this breaks some commands.
jade> dcache Data (writethrough) Cache is OFF jade> usb start (Re)start USB... USB: scanning bus for devices... 2 USB Device(s) found scanning bus for storage devices... 1 Storage Device(s) found jade> dcache on Data (writethrough) Cache is ON jade> usb start (Re)start USB... USB: scanning bus for devices... ERROR: CTL:TIMEOUT 2 USB Device(s) found scanning bus for storage devices... 0 Storage Device(s) found jade> dcache off Data (writethrough) Cache is OFF jade> usb start (Re)start USB... USB: scanning bus for devices... 2 USB Device(s) found scanning bus for storage devices... 1 Storage Device(s) found jade>
Same goes for tftpboot on this machine and also on a imx25 based system which is currently not in mainline. As there is a timeout involved I had the timer implementation under suspicion where some static variables may be used before relocation but moving them to gd_t didn't help.
Has anyone an explanation for this behavior? Is anyone out there having dcache running on an ARM926 and working usb/tftpboot?
Many thanks, Matthias
