Let me explain my issue: I have a 128mb-nand 3.5lcd mini2440 board here, and every time I try to load u-boot into RAM (according to http://bill.station51.net/index.php?post/2010/01/16/U-Boot-on-Mini2440 ) and jumping into it I get the following error: Supervivi> go 0x32000000 go to 0x32000000 argument 0 = 0x00000000 argument 1 = 0x00000000 argument 2 = 0x00000000 argument 3 = 0x00000000 ---hang--- I've already tried different memory locations and setting the definition of CONFIG_USE_IRQ to 0, 1 and just leaving it commented, in all cases I end up hanging at that same stage. The only solution I came to was to flashing u-boot to nand, switching from NOR to NAND and then booting it, but then the following happens: U-Boot 1.3.2-mini2440 (May 25 2010 - 17:46:04) I2C: ready DRAM: 64 MB NOR Flash not found.

(I just skipped that part to avoid copying more logs here) Here's a link for the image files I've used in to u-boot: http://www.megaupload.com/?d=MZI495GX (I'm using u-boot.config_use_irq_1.bin) Then, after switching it on back again I get nothing in serial, ethernet or anything..... What am I doing wrong? Curious thing: if I switch back from NAND to NOR, after about 1 second supervivi comes up, no reset needed!
