Looking at the problems with uboot versions 3.4.19 to 3.4.25, has anybody tried to use Open U-Boot mentioned in the Wiki ?
With the Marvell specific git repository it should be easy to use, i guess.
Does anybody has any experience with it ?
Regards
Carlos

I did. The USB works very well. I haven't tried too many other things. I decided to remove it because I didn't have time to look at the MAC address problem.

I tried Open U-Boot 2009.08-00285-ge1c35ea (Oct 21 2009 - 16:20:03) a few weeks ago. It was an already compiled version given by a forum member. This u-boot was only 170kB and did only support fatload, no ext2load. Because I boot from an external usb hdd I had to resize my partitions to build an additional FAT32 partition to hold the kernel files. I could fatload the uInitrd but the uImage run into a "Unable to handle kernel paging request at virtual address e1a06003" when starting the file alteration monitor (FAM).
I also recognized that the open u-boot does the same spin down at reset as the former Marvell u-boot. After that the disk does not spin up until usb start (exactly when "scanning bus for storage devices..." is executed). After a while the message "Device NOT ready" with the following rows occured:
Request Sense returned 00 00 00
1 Storage Device(s) found
So for me the same usb problem in open u-boot and Marvell u-boot. To boot properly I must power on the plug and my external usb hdd at the same time. A reset from u-boot prompt or from Debian results in a not recognized storage device.
Afterwards I switched back to Marvell u-boot 3.4.19 and the kernel boots without any problem (if plug and hdd are powered on at the same time) regardless whether I fatloaded the kernel from the FAT32 partition or ext2loaded the kernel from the ext3 rootfs partition.
From my experience I could not really recommend to switch to open u-boot. Though maybe things have changed meanwhile.

The MAC address problem I had was that the value of ethaddr does not get set at boot time and the hardware address via an ifconfig shows 00:00:00:00:00:00.
I had no problem with USB. On all of the other u-boot's that I tried usbstart worked every other time. On cold or warm boots. This one worked for me every time.
