Hi folks, I'm trying to boot a kernel image using the default n8x0_deconfig file, using the most up-to-dated linux-omap tree (commit 52a962f09ab2306a2ac6e22c2d3bac1a76ac8993). Unfortunately, this image is not booting on my N810 device. With the 'kernel low-level debugging' option enabled, I got the following messages: Uncompressing Linux............................................................................ done, booting the kernel. <5>Linux version 2.6.31-omap1-05923-g52a962f (carlos@einstein) (gcc version 4.2.1 (CodeSourcery Sourcery G++ Lite 2007q3-51)) #50 Fri Sep 11 11:08:50 AMT 209 CPU: ARMv6-compatible processor [4107b362] revision 2 (ARMv6TEJ), cr=00c5387f CPU: VIPT aliasing data cache, VIPT aliasing instruction cache Machine: Nokia N810 <4>Ignoring unrecognised tag 0x414f4d50 Memory policy: ECC disabled, Data cache writeback <7>On node 0 totalpages: 32768 <7>free_area_init_node: node 0, pgdat c024e4e0, node_mem_map c0261000 <7> Normal zone: 256 pages used for memmap <7> Normal zone: 0 pages reserved <7> Normal zone: 32512 pages, LIFO batch:7 <6>OMAP2420<6> <6>SRAM: Mapped pa 0x40200000 to va 0xe3000000 size: 0x100000 Built 1 zonelists in Zone order, mobility grouping on.
