[U-Boot] u-boot Marvell ethernet switch development

[Dennis Jacobs]

Dear U-boot mailing list,

Its the first time I make use of this U-boot mailing list. I am here for a problem I am having recently with u-boot which is part of my graduation project.

I am developing firmware for a Marvell Ethernet switch chip (98DX3336) on the RD-XC3-24G4XG-B (Marvell Ethernet switch). Marvell has provided me with U-boot binary files for UART, SPI etc. I managed to load the U-boot UART binary file trough the UART interface. Showing:

Ok so that is good... now I need to set up my own u-boot environment to add some changes. So I did. I Downloaded u-boot 2013.01 and added marvell configurations. I was able to compile and load the U-boot Uart binary trough the UART interface. The terminal is showing the following:

So ok its loads! But now... I can not perform any commands. All commands are Unknown...
So what I did was checking the configurations and I found out that I have set the CMD configurations. Like CMD_NET etc etc

Anny one that could help me here? I would really appreciate it. I am struggling with this problem for almost 2 full days now.
Actions I have been taken

-          Tested if help command was realy executed and no other invisible fragments where added.

-          Tested the compilation with 7 different armv7-marvell cross compilers

Left binary is the working one the second binary is mine. It only differs 26 bytes. I noticed that a different cross compiler also changes the size. Sometime more sometimes less. All of the binarys I compiled where executing correctly but not reacting on anny commands
