Hi,
I'm trying to gentoo running on the Media5200 but am running into issues
getting my kernel to boot. I am able to boot the kernel that came with
freescale's BSP for the device, but when I boot my kernel things stall
after Uncompressing Kernel Image:
## Booting image at 00400000 ...
Image Name: Linux-2.6.30-mpc52xx
Image Type: PowerPC Linux Kernel Image (gzip compressed)
Data Size: 2315154 Bytes = 2.2 MB
Load Address: 00000000
Entry Point: 00000000
Verifying Checksum ... OK
Uncompressing Kernel Image ... OK
I'm not completely sure why my kernel isn't booting while freescale's is. I
should have all the correct drivers enabled, but after uncompress kernel Image
nothing shows up in the console or on screen (the freescale logo/u-boot screen
stays on the screen though). I tried increasing the starting address for
kicks, but that made no differnce. I also tried doing something like:
tftp 400000; bootm 400000
but that gave me the same results as well.
Yes, I am using uImage and not cuImage.
When I compile my kernel I issue:
make ARCH="powerpc" CROSS_COMPILE="powerpc-unknown-linux-gnu-"
INSTALL_MOD_PATH="${SYSROOT}" "$@" EXTRAVERSION=-mpc52xx uImage
>From what I know EXTRAVERSION being set to mpc52xx is unnecessary, but I
saw some people doing it so I tried it for kicks. It didn't make a
difference.
Finally, my u-boot enviroment variables and version info are as follows:
