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=0xa0800000,42M"
Build ATAG
ATAG_MEM: Overwrite ram_end with real_region_top=0x20000000, memsize=512 M
ATAG_MEM=536870912@0xa0000000, MACH_TYPE=1101
Using base address 0x00200000 and length 0x00160000
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 ?
Amicalement,

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

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.

See the commands listed here:

Debian-installer kernel and ramdisk should be good:

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.

Is there any possible trap with GDB by serial (UART) ?
If so, is any one can point me to a good tutorial ?
I do not find any still valid reference or mirror download for Firmware
Recovery Unit (FRU) procedure or Technical about the IOP.
Thanks,
