Hi Fabio,
Thank you very much for your support, I'm getting closer.

OK, here what I did:

-mx35pdk arm arm1136 -
freescale mx35

init_sdram_start:
/*init_sdram*/
- setup_sdram
+ /* setup_sdram */
And here the result (output on the serial line):
---------------------------------------------------------------------------------------------------
U-Boot 2012.04.01-00077-g48bcd18-dirty (Jul 09 2012 - 15:22:31)
CPU: Freescale i.MX35 rev 2.1 at 532 MHz.
Reset cause: POR
I2C: ready
----------------------------------------------------------------------------------------------------
And that's it, no more output after "I2C: ready". Perhaps you have some more
hints about what to do?
With best regards
Michael Hornung
