Native sunxi kernel compile issues

(1/4) > >>

bitonator:
I'm trying to compile the sunxi kernel natively on my Cubieboard A10.

The steps I followed were:

1. importsce build-essential
2. loadsce build-essential
3. cp a10Core-kernel-3.0.42.config (downloaded) .config
4. make oldconfig
5. make
6. mkimage -A arm -O linux -T kernel -C none -a 0x40008000 -e 0x40008000 -n "Linux-
3.0.42" -d zImage uImage (I found the parameters by doing 'file uImage' on the tiny core kernel)

When I use this kernel, the bootloader detects the kernel images

## Booting kernel from Legacy Image at 48000000 ...
   Image Name:   Linux-3.0.42
   Created:      2015-01-18   6:05:28 UTC
   Image Type:   ARM Linux Kernel Image (uncompressed)
   Data Size:    3959024 Bytes = 3.8 MiB
   Load Address: 40008000
   Entry Point:  40008000
   Verifying Checksum ... OK
## Loading init Ramdisk from Legacy Image at 43100000 ...

   Load Address: 00000000

   Loading Kernel Image ... OK
OK

Starting Kernel...

Then, nothing, and after a while I get the bootloader again.

Am I doing something wrong?

roberts:
After step 2.
importsce uboot-mkimage
loadsce uboot-mkimage

.
.
.

Step 5 should be:
make uImage

Drop step 6.

patrikg:
U-boot.

Are you starting the kernel at correct entry point, as you enter in the mkimage.

bootm 0x40008000 0x00000000

roberts:
@bitonator

I used your mkimage parameters directly on zImage to produce uImage.
The resulting uImage was the same as the one created via make uImage.
Booting from the manually created uImage was successful.

So something else must be awry. Did you use the linux-sunxi-g2d source tree?
Perhaps start clean via make sunxi_defconfig?

expresspotato:
I have the same problem when compiling from Fedora, booting hangs with 'Starting Kernel...'

So the boot.scr, uCore, uEnv.txt are all the same from: http://tinycorelinux.net/5.x/armv7/Allwinner-A10/

This is when building the linux-3.0.42 folder. Building the sunxi-linux folder crashes on boot.
