Hi to All,
I am trying to use eMMC (as MMC2) on A20-OLinuXino-LIME2-eMMC boards without success for now.
My tests are based on Armbian with both 3.4.111 (sunxi) and 4.2.3 (mainline) Linux kernels.
Some details about configurations are published on:
- http://forum.armbian.com/index.php/topic/853-armbian-customization/page-2#entry7265 (http://forum.armbian.com/index.php/topic/853-armbian-customization/page-2#entry7265) - for kernel 3.4
- http://forum.armbian.com/index.php/topic/853-armbian-customization/page-2#entry7277 (http://forum.armbian.com/index.php/topic/853-armbian-customization/page-2#entry7277) - for kernel 4.2
I would like to ask if somebody from Olimex is testing eMMC Lime2 options and how?
Will be published new image for Lime2 with GBit Ethernet and eMMC working?
Best regards
Chris
Hey,
New image for the LIME2 with eMMC support and NAND install scripts is on the way. It has the GbE workaround applied.
It would be released by the end of this week.
Best regards,
Lub/OLIMEX
Hi,
Could someone please clarify for me;
Are olimex now shipping a version the Lime2 with emmc chip assembled? I hear sme things on the forum and blog but I can't find it in shop?
Yes they ship it (as new HW rev. E) and probably it is a question of time to updated the site.
Try specify one of the following options (as description or note to your order):
- A20-Olimexino-Lime2 - no NAN or eMMC
- A20-Olimexino-Lime2-4GB - with 4GB NAND
- A20-Olimexino-Lime2-eMMC - with 4GB eMMC
Hi to All,
I am facing at a problem to write to eMMC from U-Boot (2016.05-rc1 and 2015.10).
My try to update and save U-Boot environment finishes with fail to write to eMMC
=> setenv boot_targets scsi0 usb0 fel mmc0 mmc2 pxe dhcp
=> saveenv
Saving Environment to MMC...
Writing to MMC(0)... mmc write failed
failed
The same action works fine on SD/MMC
Any thoughts how to fix it?
Best regards
Chris

I have tested the failing case on the second a20-Olinuxino-Lime2-eMMC board I have.
And it works fine!
The problem is probably in the HW.

Hello,
I have the same problem with two Lime2 boards.
Does OLimex has any update on this ? Is this really hardware issue or something else ?
I am unable to boot from eMMC. It halts at
Trying to boot from MMC2
MMC Device 1 not found
spl: could not find mmc device. error: -19
SPL: failed to boot from all boot devices
Please help boot
Yes. There was a bug. We didn't follow our own image preparation instructions. This is now fixed.
Please use release 9 or newer.
The official Linux image was updated to release #9 and now should properly install to the eMMC memory: https://www.olimex.com/wiki/images/2/20/A20-lime2_mainline_uboot_sunxi_kernel_3.4.103_jessie_emmc_rel_9.torrent
The build instructions that go along with the official image can be found here: https://github.com/OLIMEX/OLINUXINO/blob/master/SOFTWARE/A20/A20-build-3.4.103-release-4/BUILD_DESCRIPTION_A20_Olimex_kernel_3.4.103%2B_Jessie_rel_4.txt
Best regards,

I purchased this
https://www.olimex.com/Products/OLinuXino/A20/A20-OLinuXIno-LIME2/open-source-hardware
I think I should be using this torrent because it is for NAND not eMMC?
a20-lime2_mainline_uboot_sunxi_kernel_3.4.103_jessie_NAND_rel_9.img.7z
Is that right?

Hello guys,
I'm a linux rookie having a lot of troubles following LubOlimex posted instructions:

Can anyone help me please,

Install Armbian for Lime2 and start using the board? ::) It's updated, bugfixed and should be plug and play experience. It's 100% Olimex compatible. With Debian or Ubuntu base.
This will help you:
https://www.olimex.com/forum/index.php?topic=5092.0
Thx a lot so far Igorpec, I'll try Armbian for my LIME2.
But nevertheless I'm still interested in solving the problems following the instructions posted by Lub/OLIMEX (using a brand-new SD card Olinuxino image from OLIMEX provided 5 days ago). Does anyone else has similar errors and found a solution in the meantime?
greetings
Looks like emdebian have changed things around so that things are now broken. Ask them where they are now.
John
Hey,
There is no point moving forward in the installation instructions if you fail a step. So focus on how to install the same tools that we have used or you would face many more problems moving forward.
The error you receive when you execute:
apt-get install gcc-4.7-arm-linux-gnueabihf ncurses-dev uboot-mkimage build-essential git
Means that you should try with u-boot-tools package instead of uboot-mkimage. Try with:
apt-get install gcc-4.7-arm-linux-gnueabihf ncurses-dev u-boot-tools build-essential git

Hello,
this is an request that is fit to the topic.
We have recently got the A20-OLinuxXino-LIME2-eMMC
with the corresponding SD card A20-LIME2-eMMC-DEBIAN-SD (from the end of last year).
We got our application running on the SD Card.
This system is now ready for use.
Now is the question: Can the whole file system be used from the eMMC?
I found an instruction that should do this:
In the root folder is an script "resize_sd.sh". This should bring the File System to fit in the 4 GB.
Then in the same folder the "emmc.sh" seems to copy all the files from the SD to the internal memory.
But, when I then start without the SD Card plugged. Nothing happens.
No message at the UART0 at all.
What I doing wrong?
Thanks
M. Hayer
Hey,
The official Debian image for the LIME2 board with eMMC was updated few times, maybe the card that you got didn't have the latest release. Make sure to test with the image available as a torrent at the wiki article. I recommend you to first try the two scripts, and then deploy your software, e.g. first make sure that the default image boots from the eMMC before modifying anything.
The image I recommend can be downloaded from here: https://www.olimex.com/wiki/images/2/20/A20-lime2_mainline_uboot_sunxi_kernel_3.4.103_jessie_emmc_rel_9.torrent
Also refer to this: https://www.olimex.com/wiki/How_to_install_Debian_to_eMMC
Note that sometimes the script doesn't work the first time, we don't know why this happens. You need to try it a few times until it succeeds.
Best regards,
Lub/OLIMEX
Thank for the effort it worked for me.
Now I have the problem booting from emmc, the sd-card is not recognized any more:

Is sd-card not hotplug ?
Any hints ?

I also found errors in the dmesg.log , does this mean the emmc is bad ?
