2410 board

Hello.

I have purchased a handled POS terminal with ARM9 and 2410 board in it.
Boot loader has gone bad and I need to rewrite it to NAND. 

Any operation with the device was possible over RS232, but since the OS is
missing now, COM port is no longer usable.

How can I write a bootloader to a 2410 board NAND? 

I have heard about JTAG, and it even seems like the device has JTAG pins on
the board, however I am unfamiliar with the technology and I don't even
know what I need to connect it to a PC and control it.

If someone is aware of even a general info, of how can I write a bootloader
to the device, please let me know. 

Thank you.

Isn't presented on board also NOR flash for restore bootloader in NAND? If
not then only possibility is JTAG (you can try to solder a pins and load
bootloader to NAND via JTAG).

Max, You have only the "CORE" (ARM9 proc., mems RAM, NAND and NOR)?
To get a serial COM, see the schematic of 2410 board, and find RXD0 and
TXD0. Find the GND.
Plug 3 wires and buy a DB9 female...
DB-9 pins: 5=GND, 3=RX, 2=TX
remeber, the RX of 2410 is connected to TX of DB-9...

hope that helps..
