Hi all!
Are there any known bugs for USB-storage on this CPU in u-boot?
We have a custom board based on bamboo and thinking on booting from USB instead of NAND because of the long initiation time for jffs2 on NAND-flash. At the moment JFFS2 initiation takes about 35s, and loading kernel, root-image and a fpga-image to ram take another 1m 40s.
Will it be faster if we use USB-storage instead? We are currently using USB-storage in Linux with ext3 fs.
I'll tried "usb start" command in u-boot but get the following output:
=> usb start (Re)start USB... USB: USB 1.1 Device init scanning bus for devices... 2 USB Device(s) found scanning bus for storage devices... ERROR: CTL:TIMEOUT ERROR: CTL:TIMEOUT ERROR: CTL:TIMEOUT . . . ERROR: CTL:TIMEOUT Device NOT ready Request Sense returned 00 00 00 0 blocks read: ERROR
If I then do "usb tree" I can se that the USB-storage is actually found.
=> usb tree
Device Tree: 1 Hub (12MBit/s, 0mA) | OHCI Root Hub | +-2 Mass Storage (12MBit/s, 100mA) SanDisk Corporation Cruzer Mini SNDK319F2529C8108706
"usb info" shows even more info, but "usb storage" reports no storage device.
=> usb storage No storage devices, perhaps not 'usb start'ed..?
Is USB-storage the way to go or is there a way to speed up jffs2?
Regards, André
