Replying to myself: My MPC855ADS-Board has -> U-Boot 1.1.2 (Jun 27 2005 - 11:50:05) -> CPU: MPC885ZPnn at 120 MHz: 8 kB I-Cache 8 kB D-Cache FEC present -> Board: MPC885ADS rev NR -> DRAM: (8 MB SDRAM) 8 MB
... and 8 MB Flash. AFAIK there were boards with only 2 MB RAM. Which boards do you guys have?

However, i'm still not able to run 2.6.x on the MPC885ADS. I'm now using 2.6.13-rc6 with the latest cpm-uart-fixes applied. I made the defconfig, set CONSISTENT_START to 0xe0000000 an got: Linux version 2.6.13-rc6 (root at rcf02) (gcc version 3.3.2) #5 Mon Aug 8 11:22:18 CEST 2005 Built 1 zonelists Kernel command line: console=ttyCPM0,38400n8 root=/dev/nfs nfsroot=/home/test/nfs rw ip=192.168.1.10:192.168.1.1:192.168.1.1:255.255.255.0::eth0:off PID hash table entries: 64 (order: 6, 1024 bytes) Decrementer Frequency = 450000000/60 Dentry cache hash table entries: 2048 (order: 1, 8192 bytes) Inode-cache hash table entries: 1024 (order: 0, 4096 bytes) Memory: 6244k available (1432k kernel code, 332k data, 72k init, 0k highmem) Mount-cache hash table entries: 512 NET: Registered protocol family 16 Serial: CPM driver $Revision: 0.01 $ ttyCPM0 at MMIO 0xff000a80 (irq = 20) is a CPM UART ttyCPM1 at MMIO 0xff000a90 (irq = 19) is a CPM UART io scheduler noop registered PPP generic driver version 2.4.2 PPP Deflate Compression module registere Looks like the console does not start (maybe still UART-issues)... As some people on this list reported success on MPC885ADS - can somebody please hit me with the cluebat ?
