Actually as I read it (trac gets 'muddy' sometimes, near off-topic as people explore possible interconnections) #1843 is potentially fixed four days ago by Harald Welte (laforge) and is the u-boot side of the problem, while #676 is still unfixed, which is the dfu-util side of the problem. > Disclaimer: Also, keep in mind, that updating u-boot might potentially > brick your device to a state where it needs a debug board to be > recovered. This warning ONLY applies to the Neo1973 (GTA01), NOT the FreeRunner (GTA02). The FreeRunner has a second u-boot in NOR, which you boot into in order to flash the u-boot that appears in NAND. Boot from NOR with AUX held down first then pressing power until the menu appears "U-Boot 1.3.2-moko12 (May 9, 20008 - 10:28:48)" and titled "BOOT MENU (NOR)", boot from NAND by pressing and holding power FIRST, then pressing & holding AUX until the uBoot menu appears "U-Boot 1.3.2-moko12 (Aug 26 2008 - 08:24:58)" titled "BOOT MENU (NAND)". (date on NAND will vary depending on what uBoot you've flashed, the Aug26 is what my FR shows today) The point being that when you flash a new bootloader to your FR with dfu-util (or dfu-util+neotool) you boot into NOR and flash the NAND bootloader. This means the NOR bootloader is still there, untouched, ready to serve your needs when you brick your FR with a broken NAND bootloader... ;) j _______________________________________________ support mailing list [email protected] https://lists.openmoko.org/mailman/listinfo/support
