Hi, I compiled the kernel image using buildroot for the at91rm9200 development kit (at91rm9200-dk). And I am trying to boot up the kernel using u-boot. I have tried two ways of booting it up. 1. Using bootm command (after downloading uImage): But though u-boot successfully identifies the image, the kernel does not boot up. Here is what I see on console: [/START] U-Boot> bootm 20008000

Hello all, I have built a board that contains (besides a lot of other stuff) an AT91RM9200 and an AT45DB642 dataflash chip. Now I'm trying to code a homebrew boot loader. For a number of reasons, I cannot use U-boot. The boot loader works fine when loaded using a JTAG debugger (J-link), but it won't work when I try to load it using the boot ROM code that's built into the MCU. The MCU actuall...

Hi, I'm going to run my board with AT91RM9200. My board has 32bit SDRAM (2 x HY57V561620C) data bus width. I saw that some data lines was tied together D24 D25 and D26 (close to CPU). I reworked them - now looks clear (I checked contacts too) but my memory test shows that lines D24 and D25 are still high. So my question is - Is it Atmel so fragile ? Could I broke it ?
