Update installed IGEP Firmware
From IGEP - ISEE Wiki
Now you should have a booted IGEP board with latest IGEP firmware
running from MicroSD card, you can write the firmware to the flash memory.
Enter to the IGEP Processor Board using 'root' as login name and an 'empty password', enter to the /opt/firmware and run the igep-flash script
igep-flash --image /opt/firmware/demo-image-sato-igep00x0.tar.bz2
When finish, power off your board, unplug the micro-SD card and power on the board. That's all, enjoy the new firmware running from the flash memory.
NOTE: You can speed up flash procedure. By default the
flash script runs the nandtest command to mark bad blocks, this can take a long time and in most cases is not necessary, you can speed up the flash procedure running the script as follows:
igep-flash --image /opt/firmware/demo-image-sato-igep00x0.tar.bz2 --skip-nandtest
