So, sorry, dass ich so lange gebraucht habe...
Momentan sieht es folgendermaßen aus:
- U-boot läuft...
- Kernel (2.6.28) mit jffs2 support gebaut - läuft (bis er das rootfs
mounten will...)
- Rootfs als jffs gebaut (mit Hilfe der buildroot von www.uclibc.org)
und an mtdblock2 geflasht
meine bootargs sehen folgendermaßen aus:
bootargs=console=ttyS0,115200 init=/linuxrc mem=32M rootfstype=jffs2
root=/dev/mtdblock2 rw
mtdparts=physmap-flash.0:1M(Boot),2M(Kernel),8M(root),5M(Data)
wenn ich jetzt meinen Kernel starte passiert folgendes:
U-Boot> bootm 10100000

Ich sehe nicht, was ich da falsch mache. Kann mir da vielleicht jemand
weiterhelfen?
