Newer BBB fails to enable eMMC with legacy 3.8 SD image

I have an older BBB that is flashing just fine from my SD (3.8 kernel img). When I put this same SD into a newer BBB it fails to flash because mmcblk1 doesn't exist. So I disabled the emmc flash script at the end of uEnv.txt, and did an lsblk. Sure enough there is no emmc enabled, or at least mmcblk1 is not seen/mounted.

The SD card is unchanged from one device to another, and the only thing I can see that's different is the newer one seems to be running U-Boot 2016.11-rc3-00002-g73df7f7, as apposed to the older one running U-Boot 2015.01.

If I grab a newer image (4.4) and put it on the SD, it works fine. The issue is, I need to keep 3.8 for the time being, and I need it to properly enable the emmc.

Anyone run into this type of issue? Any advice would be amazing! Thank you.

This was fixed in 3.8.13-bone80, which is the "first" 3.8.13 kernel to
support eMMC5.1..

It's not any issue in any other kernel branches.

If you "MUST" have a specific 3.8.13 version follow these directions:

and rebuild it yourself.. ;)

Thank you! Patched our custom kernel successfully with those patches. For some reason I could not for the life of me track down what had changed.

I have the same problem with the new beaglebones.

I need the 3.8.13-bone60 kernel with this patch for the new beaglebones with eMMC5.1.

How can I compile 3.8.13-bone60 with the two patches instead of the 3.8.13-bone56 ?

Here is the output with 3.8.13-bone56:

44e10800.pinmux; cannot claim for gpio-leds.8

Well, just follow the directions i posted two posts ago in this thread:

https://gist.github.com/RobertCNelson/39faf80ddc9fcefae74dce2c6ca2eb45

In the directions ^ change the 3.8.13-bone56 -> 3.8.13-bone60

When I try to compile a .deb kernel package with cmd './build_deb.sh' im getting errors

With the cmd ./build_kernel.sh I get created the 3.8.13-bone60.zImage,.dtbs,.firmware,.modules.

But how can i generate or where can I get these files which are located in my fat32 boot partition.

uImage

uInitrd

initrd.img

Here is the Output when I try to compile the kernel with ./build_deb.sh on a x86 debian9 64Bit system.
