Hi John, Today I was trying to see if I could get the ethernet driver to work with Panda, so we could try TFTP support.
Most of the patches are posted at the u-boot m-l already, that consist of the smsc95xx driver and EHCI support for Panda. With all these patches, and using the x-loader provided by omapzoom, I can make the ethernet device to work just fine, and also able to use TFTP. You can find my WIP tree at https://gitorious.org/ubuntu-experimental/linaro-u-boot/commits/u-boot-master-tftp-panda Remaining issues: * Doesn't work with the upstream version of X-Loader (probably missing some EHCI related initialization); * The SMSC driver seems to be quite unstable, as if you try to start and stop the USB it'll hang at the next time you try to start it again; * The EHCI driver duplicate a lot of code from the OMAP 3 driver, we should to reduce most of it; * Doesn't work without setting a valid mac address; * Default mac address is still 0, and we could use the same logic at the kernel to calculate the unique mac per board (using omap die ie); Would also be good to test with SPL, but don't know yet how good is the current support for it. Binaries for those who want to test at their pandas: http://people.canonical.com/~rsalveti/tftp-u-boot/ To test just hit any key to get at the u-boot shell and call 'usb start; dhcp', and you should get something like: Panda # usb start (Re)start USB... USB: Register 1313 NbrPorts 3 USB EHCI 1.00 scanning bus for devices...
