Hi,
I have SD card with custom image with kernel Linux beaglebone 3.8.13-bone50.
I flash this image to eMMC of Beaglebone Black boards successfully til now.
New beaglebone black boards have higher revision of eMMC module.
My conclusions:
Kingston EMMC04G-M627 - newer type of memory
Kingston EMMC04G-S100 - older type of memory
After boot I 've got this error:
[ 0.887052] mmc1: unrecognised EXT_CSD revision 8 [ 0.892056] mmc1: error -22 whilst initialising MMC card
I think that problem is in older kernel version of Debian.
So, I 've tried upgrade kernel via:
cd /opt/scripts/tools/
git pull
sudo ./update_kernel.sh
sudo reboot
source: https://elinux.org/Beagleboard:BeagleBoneBlack_Debian#Kernel_Upgrade
But I have problem with certificate.
After “git pull” I got error:
error: server certificate verification failed. CAfile: /etc/ssl/certs/ca-certificates.crt CRLfile: none while accessing https://github.com/RobertCNelson/boot-scripts/info/refs
fatal: HTTP request failed
I run command export GIT_SSL_NO_VERIFY=1 to workaround it.
But after “sudo ./update_kernel.sh” I got error:
GnuTLS: A TLS fatal alert has been received.
Unable to establish SSL connection
I tried to modify script adding “–no-check-certificate” after wget commands, but without success.
Can kernel upgrade solve issue with unrecognising of eMMC? If so, how can I ugprade kernel?

Internet security has really changed in the last 3 years.

Correct, this was fixed back on Jun 15, 2016...
Are you running Wheezy or Jessie?
Wheezy:
http://repos.rcn-ee.net/debian/pool/main/l/linux-upstream/linux-image-3.8.13-bone84_1wheezy_armhf.deb
Jessie:
http://repos.rcn-ee.net/debian/pool/main/l/linux-upstream/linux-image-3.8.13-bone86_1jessie_armhf.deb
With Jessie you should be able to run:
sudo dpkg -i linux-image-3.8.13-bone86_1jessie_armhf.deb
sudo reboot
For Wheezy you'll have to copy files around as it wasn't that
intergrated.. (under /boot/*)
Best to see your serial boot log to help tell you where to stick it..
Regards,
I am running Wheezie.
Debian GNU/Linux 7
BeagleBoard.org BeagleBone Debian Image 2014-05-14
I attached log file.
syslog.1 (1.78 MB)
This is result of running command od Wheezie:
root@beaglebone:/home/debian# sudo dpkg -i linux-image-3.8.13-bone84_1wheezy_armhf.deb Selecting previously unselected package linux-image-3.8.13-bone84. (Reading database ... 62413 files and directories currently installed.) Unpacking linux-image-3.8.13-bone84 (from linux-image-3.8.13-bone84_1wheezy_armhf.deb) ... Setting up linux-image-3.8.13-bone84 (1wheezy) ... update-initramfs: Generating /boot/initrd.img-3.8.13-bone84
But after “sudo reboot” nothing changed
root@beaglebone:~# uname -a Linux beaglebone 3.8.13-bone50 #1 SMP Tue May 13 13:24:52 UTC 2014 armv7l GNU/Linux
So I need to copy some files to /boot/ as you mentioned, right?
Yeap, so here's the surgery:
take a look at /boot/uboot/
ls -lh /boot/uboot/
#First backup everything:
sudo mv /boot/uboot/zImage /boot/uboot/zImage_bak
sudo mv /boot/uboot/initrd.img /boot/uboot/initrd.bak
sudo mv /boot/uboot/dtbs/ /boot/uboot/dtbs_bak/
#Copy new DTBS:
sudo mkdir -p /boot/uboot/dtbs/
sudo cp -v /boot/dtbs/3.8.13-bone84/*.dtb /boot/uboot/dtbs/
#does /boot/initrd.img-3.8.13-bone84 exist? if not:
sudo update-initramfs -c -k 3.8.13-bone84
#copy kernel files:
sudo cp -v /boot/vmlinuz-3.8.13-bone84 /boot/uboot/zImage
sudo cp -v /boot/initrd.img-3.8.13-bone84 /boot/uboot/initrd.img
and reboot..
Regards,
It works. 
Thanks.
Partition for eMMC is available again.
