Hello @all,
as part of my bachelor thesis I'm working with the stamp9g20 / portuxg20 board from taskit (http://www.taskit.de/produkte/stamp9g20/index.htm). I have a patch for a older version (2010.somewhat) of u-boot to get it running on this board, but this patch is not working anymore.
Now I'm in the process of adapting this patch to the new u-boot. Up to now I can compile a u-boot.bin and download it to the board. But after starting up the new u-boot I just see this on the serial port
---8<------------------------------------------ U-Boot 2012.04.01-00001-gadcb359-dirty (Jul 11 2012 - 19:24:58)
CPU: AT91SAM9G20 Crystal frequency: 18.432 MHz CPU clock : 396.288 MHz Master clock : 132.096 MHz DRAM: 64 MiB WARNING: Caches not enabled NAND: RomBOOT ---8<------------------------------------------
and the board is rebooting every some seconds. I'm not able to give it some input via the keyboard. I think maybe there are just some small bits missing but I'm a bit lost now ... maybe some of you can have a look and can give me some advice. ;-)
I include the old patch (portuxg20.patch) and the three patches I made in this email. My patches are based on u-boot v2012.04.01.
Thank you very much,
Markus Hubig
