Hi Michael,
Hi Fabio,
Thank you very much for your support, I'm getting closer.
The best way to generate 'u-boot.imx' is to simply do 'make u-boot.imx' and then you don't need to pass the above line manually.
In internal mode you should do:
#define CONFIG_LOADADDR 0x80800000 #define CONFIG_SYS_TEXT_BASE 0x87800000
You probably will need to skip the RAM init in board/freescale/mx35pdk/lowlevel_init.S
For a quick test I would remove the call to 'setup_sdram' there, because RAM will be inited by the values from your created imximage.cfg file.
OK, here what I did:
--- a/boards.cfg +++ b/boards.cfg
-mx35pdk arm arm1136 - freescale mx35 +mx35pdk arm arm1136 mx35pdk freescale mx35 mx35pdk:IMX_CONFIG=board/freescale/mx35pdk/imximage.cfg
--- a/include/configs/mx35pdk.h +++ b/include/configs/mx35pdk.h
-#define CONFIG_SYS_TEXT_BASE 0xA0000000 +#define CONFIG_SYS_TEXT_BASE 0x87800000
+++ b/board/freescale/mx35pdk/imximage.cfg

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
