RE: MPC885ADS and 2.6.13-rc5 - nogo ?

Hello!=20

Replying to myself: I'm able to see bootup messages on ttyCPM0 now=20
after i applied the "Made non-console uart work"-patch that i skipped
until now because, well, it was "non-console" ...

However, output on ttyCPM0 stops soon:

And that's all output for now...

Can anybody explain the "dma_alloc_init"-error ?

-----Original Message-----

Hello!

I gave the MPC885ADS support recently added by Andrei Konovalov=20
a try - but no luck: booting 2.6.13-rc5 with u-boot 1.1.2=20
(tftpboot & bootm) hangs after uncompressing.

Did anybody succeed with this?

Applied were the following patches from patchwork.ozlabs.org:

 * 8xx_cpm_hostalloc
 * all fixes to fec.c

The board boots an 2.4-Kernel just fine. Did i miss some patches=20
for U-Boot?

Best regards,

 Peter

just out of curiosity, try changing CONSISTENT_START to 0xe0000000
