![]() If everything succeeded without errors the bootloader was installed successfully and you can now continue to install the kernel and rootfs. * nand write.e X Y Z means “Go to the RAM location X (in hex) and grab the first Z MiB of data and then put it in Y NVRAM location.” * nand erase X Y means “Erase from Y (in Hex) MiB starting from X location (also in hex) If using only the single stage bootloader with default, einvironment, the 2nd stage UBoot is not used. Pro: UBoot initializes with default environment allowing automagic booting via UBIFS. Replacing 0x100000 with 0x80000 in the nand erase command. Note: This erases also the environment of the old uboot, If you are on an uboot from openwrt 14.07, you can preserve the environment by Tftpboot 0x800000 openwrt-kirkwood-dockstar-u-boot.kwb Sysupgrade openwrt-19.07.7-kirkwood-seagate_dockstar-squashfs-sysupgrade.bin Installing CC 15.05 with console access via serial connection with UBIFS This tool should work, however, going forward after 19.07.7 and up: In theory you can also use the sysupgrade tool, but this is not recommended if you don't already have a modern bootloader, uboot config, partitions, etc. # Notes that rootfs_data is untouched! Anything in /overlay will be preserved. Mtd -r write openwrt-19.07.7-kirkwood-seagate_dockstar-squashfs-factory.bin root Opkg update & opkg install openssl-util libustream-openssl20150806 ca-certificates If you do not already have that, then this procedure will not work, and you will need Serial to recover. ![]() This procedure is only recommended after a modern bootloader and uboot configuration are already in place. Upgrading the bootloader to a modern version is a requirement for booting modern kernels (3.2+) and modern filesystems (ubifs).Īfter upgrading you can inspect the version of uboot and it should be: 0圆eddc, the size of data to write, which matches how big the file was when we ran the tftboot command ![]() Start location 0x0, the beginning of the flash where the bootloader goes 0x800000, the location in ram where our data was tftpd to NAND erase: device 0 offset 0x0, size 0圆eddc You could optionally erase the entire thing if you wanted to TFTP from server 10.0.2.10 our IP address is 10.0.2.11įilename 'openwrt-kirkwood-dockstar-u-boot.kwb'. # Save this output!

The latest version of uboot that *does* work as a first-stage bootloader is from 14.07. The most recent versions of uboot on the OpenWrt downloads pages do *not* work as a first-stage bootloader.
