FlashUpgrade

The FlashUpgrade tool is used to program the parallel flash from U-Boot. It is loaded into SDRAM and executed from there, very similar to loading a Linux kernel.

This tool will let you upgrade any U-Boot, either if it is running directly from flash (old U-Boot's) or SDRAM.

For information about how to use the built flash-upgrade tool see the FlashUpgradeUsage node.

Configuration and compilation

You will need a working avr32-linux toolchain installed on your system, and an updated mkimage tool built by U-Boot.

After successfully building an U-Boot image (u-boot.bin), copy the u-boot.bin file over to the flash-upgrade directory. Flash-upgrade does not have any configuration possibilities, so just type make and you should get a flash-upgrade.uimg file.

You are now done (-: See the FlashUpgradeUsage node for information about how to take use of this file.
