Dear u-boot mailing list,
Recently I am working on a graduation project at Prodrive Technologies including the development of firmware for a Marvell Ethernet switch chip: 98DX3235. For parallel hardware/software development, I got access to another Marvell Ethernet switch chip 98DX3336 placed in a Marvell RD-XC3-24G4XG-B switching unit. To prepare a u-boot bootloader I am using the following components
U-boot version: 2013.01 Marvell u-boot configurations: 2013.01-2016_T1.0.eng_drop_v6 Cross compiler: armv7-marvell-linux-gnueabi-softfp-4.6.4_64K_i686_20160226
I also have got a working u-boot binary files from Marvell. Because I need to make changes to the u-boot configuration I need to compile my own u-boot binary files. I was able to compile a UART binary file and load it through UART using TeraTerm. At the u-boot commandline I got stuck. No commands are recognized by u-boot. See my terminal feedback below:

As you can see U-boot is loaded, hardware configurations are done, the serial interface works fine and unfortunately no commands are recognized by the u-boot. This got me thinking. My first thought was that the terminal in some way adds invisible characters to the commands. I tested this by printing all command characters separately before the Unknown command print function in u-boot. I saw that there were no other segments added to the command. I also tried using putty without any results. The binary file obtained by Marvell works fine but mine does not.
I also tried to compile and execute using 7 other cross compilers without any results.
The original Marvell UART binary file differs 24 bytes from my own compiled UART binary file. Apart from the Unknown command lines in the previously shown terminal window, both UART binary files print exactly the same information.
The only thing I can think of now is that my configuration in include/configs/<configurationfile.h>. is not well configured. A Part of the configuration file is shown below. Does someone know what is going wrong here? Do I have to change/add configurations or do I have to search somewhere else.
