Hi,
I'm trying to get the U-Boot running on the Iris board with the Toradex Colibri T20 module. I was able to flash the U-Boot and it starts but then immediately stops with the only message being:
U-Boot 2013.07 (Aug 06 2013 - 17:47:43)
TEGRA20 Board: Toradex Colibri T20 on Iris DRAM:
The Colibri T20 board used is: 256MB RAM V1.2A
Could you please give me any idea what I might be doing wrong?
Latest U-Boot worked on my Setup (Colibri T20 on the Evaluation Board). Although, I use the 512MiB variant:
TEGRA20 Board: Toradex Colibri T20 on Iris DRAM: 512 MiB
So it must be DRAM related. RAM will be initialized according to ODM data, see query_sdram_size in ./arch/arm/cpu/tegra-common/board.c. How do you flash u-boot? Using tegrarcm or nvflash? Can you verify your ODM data?
