Please see the Freescale U-boot, you missed the initialization of the CS5:

And here the result (output on the serial line):

And that's it, no more output after "I2C: ready". Perhaps you have some more hints about what to do?
Most likely it is because it will try to access the network, but you missed to setup the CS5 as per the Freescale U-boot init sequence.

Sorry for that, I really missed it. So here what I did:

-BOOT_FROM spi +BOOT_FROM sd
According to your advise I burned the image to a SD card and changed BT_MEM_TYPE[1:0] to 00 (SD, MMC, eMMC, or eSD). You are so right, flashing a SD card is a lot easier.
Then compiled a debugging version of U-Boot:
tools/mkimage -n "board/freescale/mx35pdk/imximage.cfg" -T imximage \ -e 0x87800000 -d u-boot.bin u-boot.imx Image Type: Freescale IMX Boot Image Image Ver: 1 (i.MX25/35/51 compatible) Data Size: 273724 Bytes = 267.31 kB = 0.26 MB Load Address: 877ff800 Entry Point: 87800000
and here is the visible ouput to the serial line:

After some trial and error I came up with the follwing:
+++ b/arch/arm/lib/board.c #if defined(CONFIG_HARD_I2C) || defined(CONFIG_SOFT_I2C) init_func_i2c, #endif - dram_init, /* configure available RAM banks */ + //dram_init, /* configure available RAM banks */ NULL, };

gd->relocaddr = addr; gd->start_addr_sp = addr_sp;
After those changes, U-Boot is going a little further:

The last (with my very limited knowledge) traceable function call is "relocate_code(addr_sp, id, addr);" from within "arch/arm/lib/board.c".
Maybe you have another idea what to do next?
By the way: Do you use a BDI3000 for debugging and if so, could you please send your board configuration file (.cfg) and your register definitions (.def).

Hmmm... it doesn't sound like a good idea to remove such lines.
Have you had any progress on this?
I am back to the office and can try to help you on this.

Unfortunately I had no time to look into the matter any further, but I'll try again this week.

Hi Fabio,
Have you had any progress on this?
I had some progress on my issue, here a summary of what I did:
- I configured a SD-Card as described in doc/README.imximage - I did the following changes to the U-Boot sources:

This ended up as described earlier, with an U-Boot promp stoppping with the following output:

Then I did the following change:

size1 = get_ram_size((void *)PHYS_SDRAM_1, PHYS_SDRAM_1_SIZE); - size2 = get_ram_size((void *)PHYS_SDRAM_2, PHYS_SDRAM_2_SIZE); + size2 = 0; + /*size2 = get_ram_size((void *)PHYS_SDRAM_2, PHYS_SDRAM_2_SIZE);*/
gd->ram_size = size1 + size2;

Hi Fabio,
Have you had any progress on this?
I had some progress on my issue, here a summary of what I did:
- I configured a SD-Card as described in doc/README.imximage
- I did the following changes to the U-Boot sources:

Didn't you also had to remove the init_sdram call in lowlevel_init.S ?
This ended up as described earlier, with an U-Boot promp stoppping with the following output:
CPU: Freescale i.MX35 rev 2.1 at 532 MHz. Reset cause: POR I2C: ready
Then I did the following change:
+++ b/board/freescale/mx35pdk/mx35pdk.c
size1 = get_ram_size((void *)PHYS_SDRAM_1, PHYS_SDRAM_1_SIZE);
size2 = get_ram_size((void *)PHYS_SDRAM_2, PHYS_SDRAM_2_SIZE);
size2 = 0;/*size2 = get_ram_size((void *)PHYS_SDRAM_2, PHYS_SDRAM_2_SIZE);*/
I think we should not touch this.
gd->ram_size = size1 + size2;And here the result:

At this point, there is no difference for u-boot starting the kernel if it has booted in external or internal mode. It seems an unrelated issue.
On mx35pdk you can reset the board without powerd off. You should check the address in kernel for the log buffer (__log_buf in System.map) and then check it after a reset in u-boot with the "md" command. If we are lucky, the RAM does not lose its values. Better will be if you have a JTAG debugger and can you check inside memory directly when the kernel hangs without rebooting.

Depending on the kernel version, ttymxc0 could be wrong. Have you checked it ?

Hi Fabio,
Didn't you also had to remove the init_sdram call in lowlevel_init.S ?
No, I didn't change it since it seems not to make any difference. Hope we're talking about the same, I changed the following and it did not make any difference whether it was commented or not:
+++ b/board/freescale/mx35pdk/lowlevel_init.S
init_sdram_start: /*init_sdram*/ - setup_sdram +/* setup_sdram */
Then I did the following change:
+++ b/board/freescale/mx35pdk/mx35pdk.c
size1 = get_ram_size((void *)PHYS_SDRAM_1, PHYS_SDRAM_1_SIZE);
size2 = get_ram_size((void *)PHYS_SDRAM_2, PHYS_SDRAM_2_SIZE);
size2 = 0;/*size2 = get_ram_size((void *)PHYS_SDRAM_2, PHYS_SDRAM_2_SIZE);*/I think we should not touch this.
Hey, but it works (halfways) :-)

Because the RAM is already set up via the imximage.

Hey, but it works (halfways) :-)
It depends on your mx35pdk. The board can be equipped with one or two banks. If it works commenting these lines, it means that in your imximage.cfg you set only one bank. The setup_sdram() sets both banks.
Could you please give me some hits what to do next?

A first quick try ended up with the following (I'll try harder today:
Mmhh...you had already a running u-boot - your problem is moved, because the kernel is not correctly started.
I think you should start from this condition (the running u-boot) and try to understand where the kernel hangs. This can be of course something related to u-boot and in u-boot code, but trying to disable things that worked can be completelky unrelated.
By the way, if you set CONFIG_SYS_NO_FLASH, you should also set that the environment is embedded (that means, you have only the default) and deactivate the flash driver (CONFIG_CFI).
