Hi,
I finally tried the mighty davinci git kernel. ;)
I'm able to make it start on EVM and on my board, that's ok.
unfortunately, I'm having some trouble in taking the rootfs from the SD
card.
I found that with "ip=dhcp" in the cmdline, it handles correctly the mmc
slot and recognizes the card inserted into it...
(well, actually he hangs on starting cron service, but that's another
tale!) ;)
I see something like that:
...
mmc1: new high speed SD card at address b368
mmcblk0: mmc1:b368 USD 1.85 GiB
mmcblk0: p1
...
Instead, without "ip=dhcp", or with "ip=none", it doesn't sees any mmc card
at all:
....
Root-NFS: No NFS server available, giving up.
VFS: Unable to mount root fs via NFS, trying floppy.
VFS: Cannot open root device "mmcblk0p1" or unknown-block(2,0)
...
( can't stand why he search for a root-nfs too... )
I'm attaching both the boot log, on a DM355EVM board.
Any ideas?
Thanks, bye!
