Hi all,

I'm trying to get Linux booting on an ARM7 (NXP LPC2468). I copy the uImage to 0xa1500000 and the romfs.bin to 0xa1800000. I set bootargs to: root=/dev/ram initrd=0xa1800000,4000k console=/dev/ttyS0,115200N8 When I do 'bootm a1500000', it finds the image and tries to uncompress it, but it goes silent after printing "Uncompressing Kernel Image ..." When I try to create the uImage with 'mkimage -A arm -O linux -T kernel -a 0 -e 0 -n "Linux Kernel Image" -d linux.bin uImage', I get the following output (mind the absent -C flag):

---

Image Name: Linux Kernel Image Created: Thu Mar 12 15:37:01 2009 Image Type: ARM Linux Kernel Image (gzip compressed) Data Size: 1986268 Bytes = 1939.71 kB = 1.89 MB Load Address: 0x00000000 Entry Point: 0x00000000

---

bootm also still thinks that the image is compressed and bootm prints: Uncompressing Kernel Image ... Error: Bad gzipped data GUNZIP: uncompress or overwrite error - must RESET board to recover

How can I make sure that the Linux image can boot?

I just noticed that when I set the load and entry address to 0xa0000000 (the start address of my external RAM), then bootm prints "starting kernel" and then U-boot resets itself twice.... I think I have no idea what's going on here. Is this a problem in my U-boot or is it already in the kernel?

Kind regards,

Are you sure these are correct? 0x0000 is usually a ROM address on ARM; I don't think you can load and run your kernel image there.
