Hi,
I've got a NAS which uses uboot: U-Boot 1.1.4 (Feb 6 2012 - 14:40:46) Marvell version: 3.4.27
It's a Netgear ReadyNAS Duo V2, and the original sofware sucks. ;)
I would like to start with the original kernel (because it contains some patches) and a custom debian made with multistrap.
Where do I start?
I'll add some information about the config.
I believe these are the most important boot options.
standalone=fsload 0x2000000 $(image_name);setenv bootargs $(console) root=/dev/mtdblock0 rw ip=$(ipaddr):$(serverip)$(bootargs_end) $(mvPhoneConfig); bootm 0x2000000;
bootcmd=nand read.e 0x1200000 0x200000 0x600000;nand read.e 0x2000000 0x800000 0x1000000;bootm 0x1200000 0x2000000
bootargs=console=ttyS0,115200 reason=normal mtdparts=nand_mtd:0x180000@0(u-boot),0x20000@0x180000(u-boot-env),0x600000@0x200000(uImage),0x1000000@0x800000(minirootfs),0x6800000@0x1800000(jffs2);
there are 5 mtds: 1,5M mtd0 - ? 128K mtd1 - ? 6,0M mtd2 - kernel 2,2M mtd3 - initrd (gzipped) 89M mtd4 - jffs2 image, I think it contains a rescue image of the filesystem which is applied to the harddisks.
I dumped the kernel from mtd2, it is: u-boot legacy uImage, Linux-2.6.31.8.duov2, Linux/ARM, OS Kernel Image (Not compressed), 3442208 bytes, Tue Aug 28 05:21:43 2012, Load Address: 0x00008000, Entry Point: 0x00008000, Header CRC: 0xDA1ECA31, Data CRC: 0x269C27DE
I tried to load the kernel through tftp, but it crashed:
Marvell>> dhcp

thanks for any help,
