I have a small openwrt image which i want to use to chain into another openwrt image in another mtd partition. I have carved up the flash properly with the .dts and makefile's for my targets.
So i have /dev/mtd3 which is being started by uboot, and i want to chain into /dev/mtd4 which has another version of openwrt installed on it. (Standard sysupgrade image, 64 byte header, kernel, sqfs, trailer for jffs2) Obviously i need to use kexec. Is it possible to run kexec on the image in the mtd partition directly, or do i need to first extract the kernel into ram to run kexec on it? What about the sqfs, does the kernel find that in the mtd or do i need to pass it in to kexec also? the dts in the /dev/mtd4 image has the `compatible = "denx,uimage";` option set on /dev/mtd4 and /dev/mtd3 is renamed "reserved" and is read only. I am trying to use the kexec-tools command line tool to do this. _______________________________________________ openwrt-devel mailing list [email protected] https://lists.openwrt.org/mailman/listinfo/openwrt-devel
