Brian,
I have encountered the same problem. I'm running 2.6.23-davinci kernel and
trying to config
EVM as a USB host. I can read/write data to EVM board. But when i copied a
large size file,
some errors will appeared. I turned on the kernel debug and usb verbose debug,
some error messages
: 10MB/sec
does this make it clear?

I can see many peoples contributing on GIT kernel and I want to thank
everyone making effort.

Sorry, I forgot there is another question.
About the performance, Lee have did speed benchmark, Please refer this link:

As far as I know, USB host mode with DMA support doesn't work at gi

hi Wu, Ruiyu
I think this wiki page will guide you to do it:

ERROR "Verifying Checksum ... Bad Data CRC"
please verify whether kernel size exceed flash partition size.
I'm successful in booting from jffs2 filesystem on NAND
Lee, Swami,
I did a simple and quick test. The kernel was also configured with
default setting.
It seems this patch fixed USB stability issue.
test case:
~ 20 files, about 100MBytes every file.
Speed benchmark result on git 2.6.25

Read: 3.6M By
to the USB HDD's under DMA mode.
Many more MUSB fixes need to be done still compared to the 2.6.10 kernel MUSB
driver. I am planning to do the same gradually as seperate patches.
Any way I can reproduce your test setup ?

I'm testing USB driver with DMA support. My custom board have 256M
DDR memory.
When i set mem=112M in bootargs, USB works well with DMA mode. When i
set mem=120M,
kernel boot ok, but USB driver crashed while writing. I thought it
caused by system memory map.

Paddy,
It's glad to know you also uses 2.6.23 kernel. Does the IDE HDD
works on your board?
I encountered the "IDE hdd cannot mount issue":

Existing evm USB performance is pretty bad (host only performs at about
10mbps), I am looking at the Archos tree which is supposed to have a
faster Davinci USB host, but I wonder if there is any other patch
available for 2.6.23 or even for 2.6.10
