Re: N2100 Bricked - Redboot rescue needed
Hi, Thanks for answers. You can use the kernel and initrd of the Debian installer listed at http://cyrius.com/debian/iop/n2100/install.html to boot into the Debian installer. Then you can access the hard drive and re-flash the kernel/ramdisk from the system. See http://www.cyrius.com/journal/debian/installer-flash-kernel I have update my wiki page, for this rescue procedure [1]. IIRC I saw that when I had a bad ram DIMM installed. So it could be that some of your hardware components has got loose/dusty. I will give a try, but I think I may have bricked the RedBoot. Is there a serial RedBoot rescue mode possible, like in UBoot [2] ? Is there any technicals references or tools for booting RedBoot by serial ?

Note if you believe that redboot is bricked, any rescue mode *in* redboot wouldn't help. What you describe in your uBoot link is not a uBoot feature, but a kirkwood SoC feature. N2100 comes with intel iop321 SoC, and I dont remember if it has a serial boot mode. If it has, it can be discovered from the Intel Technial reference manuals[1]. If IOP doesn't come with a serial boot feature, you will essentially need JTAG access. Or alternatively desolder the flash chip and flash it with separe flasher board.

N2100 Bricked - Redboot rescue needed
Hi, I have two Thecus N2100 Bricked and make a call for some help ! I have soldered a RS232 on the SATA Board, as explained here and [1] on my wiki [2]. With the serial console I have one of the Thecus that only show a + at Boot. The other one hang at booting debian kernel : RedBoot exec -c console=ttyS0,115200 root=/dev/ram0 initrd=0xa080,42M Build ATAG ATAG_MEM: Overwrite ram_end with real_region_top=0x2000, memsize=512 M ATAG_MEM=536870912@0xa000, MACH_TYPE=1101 Using base address 0x0020 and length 0x0016 Is there any method to get the kernel and initrd from TFTP and reflash them into RedBoot ? Where can I get the kernel and initrd ? Is there any rescue method for Debian without bricking ?
