Are there any known bugs for USB-storage on this CPU in u-boot?
Sorry, but I never tested it. The PPC440EP USB port was done by Embedded Planet for the initial Yosemite port.
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.
Hmmm. Why don't you partition your NAND chip and use the RAW-NAND interface (e.g. nand read...). This will bring you the fastest boot time.
Best regards, Stefan
