Updating the BIOS backup copy is prohibited if the module doesn't boot from the main
BIOS copy.
3. Copy the SPIFLASH folder from the FTP server to the module's boot disk. Place the updated
BIOS image (e.g. c307v310.bin) into the copied folder.
4. Make sure the XP21 jumper is installed. The XP26 jumper must be removed.
5. Run the WDTRST.EXE program to activate the WDT2 timer and reboot to the BIOS backup
(located in the SPIFLASH folder).
C:\SPIFLASH\wdtrst.exe
After the module reboot, the optimal (factory default) BIOS Setup settings can be loaded. If
necessary, enter the BIOS Setup, change the necessary parameters, save and exit (paragraph 5.7
Exit).
6. Start BIOS update program from the SPIFLASH folder with the
“u” key and specify the updated
BIOS image:
C:\SPIFLASH\spiflash.exe u c307v311.bin
If the update is successful, the program will display the following messages:
SPIFLASH 1.11 (May 21, 2008)

CPU name = Vortex86DX
SPI base address = fc00
send RDID cmd

Flash type = MX25L1605, ok
Update flash rom data from c307v311.bin:
ADDR : 40000/40000

Ok
7. After update of the BIOS backup copy you need to run the WDTRST.EXE program in order to
restart the module from the BIOS backup copy and verify the correctness of the update!
After the module reboot, the optimal (factory default) BIOS Setup settings can be loaded. If
necessary, enter the BIOS Setup, change the necessary parameters, save and exit (paragraph 5.7
Exit).
If the module boots, the BIOS backup copy is updated successfully.
If updating the main BIOS copy led to an error and the module fails to boot (no information about
the POST procedure being passed, and the console output was enabled), or the WDT2 watchdog
timer goes off (jumper XP26 is removed, the module is periodically reset), in this case you must:
1. Set the XP21 jumper and remove the XP26 jumper.
2. Power on the CPC307 module and boot from the BIOS backup copy (WDT2 watchdog will be
triggered if the main BIOS copy is damaged).
