<br>
I've followed closely the wiki on "How to build Debian from source" on rhombus-tech.<br>
I have a MeleA1000 but no USB serial converter so I can't see the kernel console while booting.<br>
<br>
I've a working configuration of the kernel + rootfs, with a debian squeeze.<br>
Now, I'm trying to get the 512M available for the server, but I'm probably missing something since I can only get<br>
395MB out of the 512MB.<br>
<br>
Here's my config:<br>
# cd linux-allwinner<br>
# git log<br>

Hide MALI DRM driver if MALI is not enabled. Does not actually seem<br>
to depend on MALI drivers but is useless without them.<br>

Clean up MALI driver integration<br>
<br>
- Can only be built as module<br>
- Enabled via defconfig, not hardwired in the target architecture<br>
- Rename CONFIG_GPU_MALI to CONFIG_MALI<br>

I've disp_init_enable=0 in my fex file too.<br>

Any idea about what I'm missing ?<br>
