Hi,
I've come across an issue using a USB Ethernet adapter in U-Boot. I am
still investigating where the problem is. This email is to let people
know that a problem exists.
I have included the output of "usb info" below, which includes the
vendor/product-id of the specific adapter I am using.
When using DriverModel, I get a number of "EHCI timed out on TD -
token=…" messages. Eg, trying to ping a connected PC.
When I disable DriverModel for Ethernet the USB Ethernet interface works
fine. I am able to ping, and to TFTP a file over and confirm that the
crc32 is correct.
To disable DriverModel for Ethernet I removed "select DM_ETH" from
ARCH_MVEBU in arch/arm/Kconfig, and removed CONFIG_MVNETA from
arch/arm/mach-mvebu/include/mach/config.h to get it compiling again.
The board I am using is a Marvell DB-88F6820-AMC, which has an Armada
38X CPU.
