Re: Update firmware with a custom image
The normal firmware upgrade method that Daniel describes occurs after operating system install, but before first boot of the operating system ... provided external power is available. After the firmware upgrade, the next boot occurs automatically and the operating system takes control. I can imagine situations where firmware should be updated before operating system install, but we tried to avoid them during development. The scenarios include: - use of fs0.zip and fs1.zip on same USB drive, (very old XO-1 firmware does not look for fs0.zip); workaround is to copy fs0.zip to fs.zip, - now fixed firmware bugs that prevent copy-nand or fs-update completion. It doesn't include scenarios of USB drive incompatibility, since the fixed bugs in that realm would also prevent automatic firmware upgrade from a USB drive. If you have scenario where operating system must have later firmware version for successful use, then you must also ensure external power is connected on first boot. -- James Cameron http://quozl.linux.org.au/ ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

Is it the case? Yes, check the packages.txt output file from olpc-os-builder, look for the bootfw or olpc-firmware-q* package version. That firmware is included in the image and laptops will auto-upgrade on first boot. > Is there a way to upgrade the firmware easily from the customized > bootloader? It's possible, but it might be a little tricky since you would have to put appropriate code in your olpc.fth boot script on the USB disk. For simplicity I would stick with the OS-embedded firmware upgrade unless that is going to be problematic. Daniel ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
Update firmware with a custom image
Hi all, Ive created my own image using OS Builder and customized the bootloader. So Ive got now an USB key that update the os image but I wonder if the key could update also the firmware version. I understand that the OS Image embed a new firmware. Is it the case? Is there a way to upgrade the firmware easily from the customized bootloader? Best regards from France.
