There is partition FAT in the flash disk.

Another question. If add code to handle OHCI ED and TD, Can I still use
bulk_transfer and control_message?

Regards

YH

Greetings,

I'll see if I can dig up the old debugging captures, I may still have
them.

The enumeration of the USB bus looks good. The problems seem to start
with:
536870913 536870912 byte blocks
ll_read_block returns 512
0: boot=00000000, start=00000000 length=00000000
1: boot=00000000, start=00000000 length=00000000
2: boot=00000000, start=00000000 length=00000000
3: boot=00000000, start=00000000 length=00000000

GEt capacity returned a VERY unreasonable result :-)

The read of the partition block seems to have actually read the block.
Does the drive have a partition table on it?

If not, try putting one on it and trying the boot so we can see if it
actually read the block correctly or if the data went to the wrong place.

G'day,
sjames
