General

You can use this as one method to un-brick your Neo1973, in case your bootloader has been corrupted.

sjf2410-linux is a linux-enabled version of the sjf2410 tool.

It allows you to use a wiggler compatible JTAG Probe to program NAND and NOR flash attached to the S3C2410 (In the Neo1973, we only use NAND flash).

Object Code

The latest release can be found at https://buildhost.openmoko.org/tmp/gta01/deploy/images/sjf2410

Source Code

The current sources are kept in https://svn.openmoko.org/trunk/src/host/sjf2410-linux/

Usage

To flash a u-boot image into NAND flash

basically you have to start the program with option '-f' to specify the file you want to flash.

Then, verify that it actually detects the S3C2419 CPU.

In the Main Menu, select '0' for 'K9S1208 prog'. In the prog menu, select '0' for 'K9S1208 Program' and then '0' as the block number.

Example

$ sjf2410 -f ~/u-boot_nand-gta01bv2-20070104112711.bin
