I am busy with two part process; first is quick fix to keep our production line running but patching and rebuilding 3.8.13 image to enable flashing to newer eMMC devices, the second is to bring product to more current version.
I am drawing a blank on how I originally created my BBB image after building the kernel, I don’t recall using the script file and am battling finding any relevant links.
Files generated by build are:
-rw-rw-r-- 1 vagrant vagrant 37713 Jan 12 22:37 3.8.13-bone80a-dtbs.tar.gz
-rw-rw-r-- 1 vagrant vagrant 1259472 Jan 12 22:37 3.8.13-bone80a-firmware.tar.gz
-rw-rw-r-- 1 vagrant vagrant 12029365 Jan 12 22:37 3.8.13-bone80a-modules.tar.gz
-rwxrwxr-x 1 vagrant vagrant 5551080 Jan 12 22:37 3.8.13-bone80a.zImage
-rw-rw-r-- 1 vagrant vagrant 110269 Jan 12 22:37 config-3.8.13-bone80a
First prize would be to update the SD card I use to flash the beaglebone, else I guess I could use build-deb, copy deb file to BBB with older kernel and update using the deb and recreate my flasher sd card.
Thanks, will give it a try: I broke my git tree trying to sync so am rebuilding now, but here’s output of startup log:

Just use “./build_deb.sh” or “./tools/rebuild_deb.sh” and copy the linux-image*.deb from ./deploy/ and just install it on the board with “sudo dpkg -i linux-image*.deb”
So I wasn’t using am33x-v3.8 although did try it but don’t recall offhand what the issue was. I have been using tag 3.8.13-bone68 as that is what my original build was and I wanted to keep changes to a minimum (as this was meant to be a quick fix).
Am I correct in assuming that am33x-v3.8 is the latest iteration for 3.8.xx - ie could be 3.8.xx-boneYY
I also found an old script I had created. Looks like I transfer output of build to BBB and then ran script below - risk as it’s very specific to the BBB layout.
As mentioned I have been working with 3.8.13-bone68 tag which is STILL building… but will try the am33x-v3.8 which I recall failing but will try and the .deb route does sound the best

Another question. for am33x-v3.8 branch how does one prevent downloading of toolchain and linux-stable.git? I must be doing something wrong as each time I run build_kernel it downloads linux src as well as toolchain (I am rerunning as my rebuild.sh failed after my patch and I want to catch logs).
I thought in setting CC and LINUX_GIT in system.sh should be sufficient to prevent download and rather use these static files.
Looking at scripts/git.sh it appears that LINUX_GIT can be full path to folder containing downloaded linux source.
so am rebuilding now, but here’s output of startup log:
