Hello Everybody,
its me again =) I have a problem booting L4 on the Sheevaplug. I have
built L4re, Fiasco and also L4Linux for arm platform and built an
uimage by calling
"make image E=L4Linux-arm BOOTSTRAP_DO_UIMAGE=y
SUPPORT_CC_armkirkwood=y
MODULE_SEARCH_PATH=/opt/arm/fiasco:/opt/src/l4/conf/examples:/opt/arm/l4linux:/tmp"
Everything worked fine. Than I copied the image to my usb stick and
tried to boot it on the Sheevaplug with UBoot. I got the following output:
Marvell>> usb start
Marvell>> fatload usb 0:1 0x00800000 /bootstrap_l4linux-arm.uimage
Marvell>> bootm 0x00800000
## Booting image at 00800000 ...
Image Name: L4 Image #11
Created: 2011-11-08 10:20:15 UTC
Image Type: ARM Linux Kernel Image (uncompressed)
Data Size: 8028328 Bytes = 7.7 MB
Load Address: 01000000
Entry Point: 01000000
Verifying Checksum ... OK
OK
Starting kernel ...
And then nothing happens after that. I also tried the simple
'Hello'-Example without L4Linux, and it also didn't work. Or at least
I get nothing to see...
I think the problem is the serial console. But how can I tell L4 that
the output should be send to this same console? (I'm connected to the
Sheevaplug via MiniUsb->Usb 'screen /dev/ttyUSB0 115200').
I hope someone can help me.
Thanks in advance.
Cheers,
Julian
