There should be. sure. it's what I set into bootcmd.bak: >> fw_setenv bootcmd.bak 'nand read.e 0x1200000 0x200000 0x600000;nand >> read.e 0x2000000 0x800000 0x1000000;bootm 0x1200000 0x2000000' the outputs all looked fine, after I changed the offset in config file to 0x0. Else I wouln't have written anything. But still I am not 100% sure about the sector size of 0x20000 (128KByte) > Yes: get control through JTAG. Ok.

I've got the following soldering points: - a 1x3 Pin@2,54mm connector labeld J7 which could be a FAN connector. - a 2x5=10 PIN@2mm connector J1 near the ROM chip. both connectors are on this picture: http://natisbad.org/NAS/pics/NETGEAR_ReadyNAS_Duo_v2_RND2000-200EUS_J1_and_J7_provisions.jpg - 1x4 PIN @ 2,54mm connector. So which one? Do I have to guess the pins? which probe should I chose? Something like these? - Embedded Projects OpenOCD-USB Adapter - Xilinx JTAG Parallel Cable III FPGA CPLD programmer LPT - SainSmart USB Blaster Programmer Cable For FPGA CPLD JTAG Development Board - found a LPT programmer having nothing more than a 74HC244 chip. Id' prefer the USB adapter... btw, I found out there is a boot menu. When I hold the reset button during bootup, there is a boot menu offering: Normal. Factory default. I believe it loads the initrd to reformat the harddrives. OS Re-install. Installs the root fs to hard drive from JFFS rom. Skip volume check. Memory test. Performs a memory test. Disk test. Maybe Smart test. I tried most. They all freeze after printing "net: egiga..." except memory test. Won't help much, I believe, since most rely on the boot process which is broken.
