Updating a corrupted system using a debugger

If the Flash memory has become corrupted and the system cannot boot anymore, then the
Flash memory must be re-programmed using the JTAG interface and the JTAG-Booster.
Connect the JTAG-Boosters 8-pin connector to the development board (JTAG X12). The
two black cables point to pin 1.
Set DIP-switch S4-1 to "on" and S4-2 to S4-8 to "off".
Copy the JTAG tools from the LxNETES-3.2 CD to the host system. A detailed manual
how to setup the JTAG-Booster can be found on the LxNETES-3.2 CD, hardware/jtag.
On a Linux system use a tool like dosemu to get the JTAG tools running.
Once you have installed the JTAG tools on your host computer, copy the U-Boot image
that you want to program into the Flash memory, to the same directory and execute the
batch file to flash U-Boot.
After a successful programming of U-Boot, the kernel and the Root File System can be
updated (if they were corrupted, too).
