Hello to everybody, previously I have had some doubts to run a Linux kernel on this evalboard. Especially to find a BSP for my board .... In the meantime I have had some problems which I was able to solve by myself or reading through different forums. I still have some problems with Barebox and it's ECC for the NAND-Flash and also the asterix * in this nand -a /dev/nand0.* is not working. (It is working when I am doing it manually). But in total I am able to load and start Barebox and then again loading and starting the kernel. First I have seen nothing until I switch on the special function earlyprintk=serial,ttyS0,115200n8 After that I saw that I have mounting/partitioning problem, so I changed the board specific init.c in that way that the first three partitions match exactly to the definition in the configuration file for the init script of Barebox. init.c > devfs_add_partition("nand0", 0x00000, SZ_128K, DEVFS_PARTITION_FIXED,"at91bootstrap_raw"); dev_add_bb_dev("at91bootstrap_raw", "at91bootstrap"); devfs_add_partition("nand0", SZ_128K, SZ_256K, DEVFS_PARTITION_FIXED, "self_raw"); dev_add_bb_dev("self_raw", "self0"); devfs_add_partition("nand0", SZ_256K + SZ_128K, SZ_128K, DEVFS_PARTITION_FIXED, "env_raw"); dev_add_bb_dev("env_raw", "env0"); env/config > nand_parts="128k(at91bootstrap),256k(barebox),128k(bareboxenv),4M(kernel),80M(rootfs),-(data)" rootfs_mtdblock_nand=4 rootfs_mtdblock_type=jffs2 After that I was really happy that the kernel is prompting "VFS: Mounted root (jffs2 filesystem)" But the next kernel panic is near It cannot find a init script. I tried init=/bin/init, init=/sbin/init init=linuxrc everything with out success each time the same failure occur. I also tried to execute a simple command like init=/bin/ls ... But I see in sysroot-target a softlink linuxrc -> /bin/busybox and also in the root-folder root/sbin/ init-> ../bin/busybox Waht is the difference of those directories? (I thought the root folder is the result for the target, so everything in there will be contained in the root.jffs2) I have also changed in busybox between soft and hard links ... How can I solve this problem? Has anyone a hint for me, pls?
