I am working with a PXA270 module. Our hardware includes a ISP1761 (NXP USB2.0) and we are trying to get the USB 2.0 to work. I am trying to debug and have great difficulty with Platform Builder. I build the debug image, the using Tera Term I catch the unit on power up, then send the bootme &, then start the download. First of all, the download of the OS is very slow. It takes 30 minutes and the image is only 10MB. The big problem is that most of the time it fails to load. Any ideas on how to make this work better? Crashes a lot. If it ever loads the whole thing, then I can kick it off and start debugging my new Host USB driver, but it almost never works. Debugging the driver is making me nuts.

It might crash at 4%, or 50%, or even 98%.

It crashes differently every time, but here is the gist of the failure as it happened just a moment ago:

.......section 17: phy_addr: 0xa03f4000 phy_len: 0x0009dcc0 cksum: 0x0414fb7c
section 17: unable to read (1)(11)
error: bootme: general load failure()
load failed

Ideas?
