emmc flashing from linux host

I'm also trying to flash eMMC of BBB according to (http://processors.wiki.ti.com/index.php/Sitara_Linux_Program_the_eMMC_on_Beaglebone_Black). In Windows uniflash started with status "NewlyCreatedDevice" and later status changes to "FlashUnknownError".

In Linux i have configured tftp server and dhcp server, but can't understand how to initiate flash process. This information can't help me:

1. Set the Beaglebone Black to boot from Ethernet.
2. Connect cables as necessary and boot the board.
3. Stop U-Boot.

         1. Use the procedure from earlier labs to Ethernet boot. This will run the init script and TFTP the flasher.sh, and execute it to program the eMMC.

I don't know how to boot Beagleboone Black from Ethernet and can't find appropriate information on the Internet and hope here i will find help. And if exists manual for ceating eMMC flasher SD card i would like to see it.

Thanks in advance.

Hi,

Follow the instructions:
* Flash Beaglebone Black's eMMC (verified with AM335x SDK 07.00.00.00):
http://www.adminempire.com/how-to-install-arch-linux-on-beaglebone-black-bbb/

1. Prepare a SD card either with the create-sdcard.sh script or:
On the host PC with the SD card inserted:
1.01. sudo fdisc /dev/sdd (or /dev/mmcblk0)
1.02. o - this clears the existing partitions
1.03. p - this lists all partition tables on the card (there should be none)
1.04. n - create a new partition
1.05. p - primary partition
1.06. 1 - partition number
1.07. 2048 - default value for the first sector
1.08. +64M - last sector / partition size
1.09. t - change the partition type (select partition 1)
1.10. e - change tha partition type to "W95 FAT16 (LBA)"
1.11. a - set the bootable flag for the selected partition (1)
1.12. n - create a new partition
1.13. p - primary partition
1.14. 2 - partition number
1.15. hit Enter to choose the default (next available) value for the first sector
1.16. hit Enter to choose the default (last) value for the last sector
1.17. p - this lists all partition tables on the card (there should be two)
1.18. w - write all the above changes to disk
1.19. sudo mkfs.vfat -F 16 /dev/mmcblk0p1 (or /dev/sdd1) - format the first partition
1.20. sudo mkfs.ext4 /dev/mmcblk0p2 (or /dev/sdd2) - format the second partition
1.21. copy the {MLO,u-boot.img,uEnv.txt} files to the first partition:
# mkdir boot
# sudo mount /dev/mmcblk0p1 boot
# cp {MLO,u-boot.img,uEnv.txt} boot
# sudo umount boot
1.22. copy the root file system to the second partition:
# mkdir root
# sudo mount /dev/mmcblk0p2 root
# tar -xf tisdk-rootfs-image-am335x-evm.tar.gz -C root
# sudo umount root

2. Run the BBB from the SD card (hold the USR button when powering the board up)

3. ssh into the board:
# ssh root@172.20.0.111

4. The eMMC is /dev/mmcblk1. Format it this way:
4.01. fdisk /dev/mmcblk1
4.02. o - this clears the existing partitions
4.03. p - this lists all partition tables on the card (there should be none)
4.04. n - create a new partition
4.05. p - primary partition
4.06. 1 - partition number
4.07. 2048 - default value for the first sector
4.08. +16M - last sector / partition size
4.09. t - change the partition type (select partition 1)
4.10. e - change tha partition type to "W95 FAT16 (LBA)"
4.11. a - set the bootable flag for the selected partition (1)
4.12. n - create a new partition
4.13. p - primary partition
4.14. 2 - partition number
4.15. hit Enter to choose the default (next available) value for the first sector
4.16. hit Enter to choose the default (last) value for the last sector
4.17. p - this lists all partition tables on the card (there should be two)
4.18. w - write all the above changes to disk
4.19. umount /dev/mmcblk1p1; mkfs.vfat -F 16 /dev/mmcblk1p1 - format the first partition
4.20. umount /dev/mmcblk1p2; mkfs.ext4 /dev/mmcblk1p2 - format the second partition

5. Copy the {MLO,u-boot.img,uEnv.txt} files to the first partition:
# mkdir boot
# mount /dev/mmcblk1p1 boot
# cp {MLO,u-boot.img,uEnv.txt} boot
# umount boot

6. Copy the root file system to the second partition:
# mkdir root
# mount /dev/mmcblk1p2 root
# tar -xf tisdk-rootfs-image-am335x-evm.tar.gz -C root
# umount root

7. Shutdown the BBB, remove the SD card and start it from the eMMC.

Hi.

Thaks for answer Ivan. I tried your method. I used "MLO" and "u-boot.img" files from this directory:

~/ti-sdk-am335x-evm-07.00.00.00/board-support/prebuilt-images

("MLO-am335x-evm" and "u-boot-am335x-evm.img" renamed to "MLO" and "u-boot-img") to write them on boot partition on Beaglebone (/dev/mmcblk1p1). And root partition (/dev/mmcblk1p2) i filled with files from archive

"tisdk-rootfs-image-am335x-evm.tar.gz" found here:

~/ti-sdk-am335x-evm-07.00.00.00/filesystem.

After restart BBB does nothing. LED doesn't blink and system doesn't loading. What i missed?

Thanks in advance.

I realized that boot partition from eMMC loads linux fs from sd card. I've built u-boot like this: make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- O=emmc am335x_boneblack. How i can make beaglebone to boot file system from eMMC?

Hi Chris,

This explanation is possible only for BBB. The beagle bobe white this is not true, because there is not eMMC. If you have BBB you have to use BeagleBone Black Connector and Switch for booting from sd-card and eMMC. See the:
http://www.elinux.org/Beagleboard:BeagleBoneBlack

BR
Ivan

I'm working with Beaglebone Black. As I understand, boot switch can be used to load from SD card, but when I don't touch the boot switch, u-boot must be loaded from eMMC. So, after I did changes on the eMMC (/dev/mmcblk1) according to method you provided, BBB uses u-boot from the eMMC, but rootfs is loaded from SD card. This is not the behavior I expected.

This uEnv.txt file didn't help me. Looks like device doesn't react on uEnv.txt. I did changes in "am335x_evm.h" of u-boot from sitara SDK (.../board-support/u-boot-2013.10-ti2013.12.01/include/configs/am335x_evm.h) like "Srini S" said. Now BBB doesn't loads without sd card when eMMC boot partition is used, but mmcblk1p2 is mounted as rootfs. Maybe i have to change something else in u-boot parameters, except this:

bootpart=1:2
mmcroot=/dev/mmcblk1p2.

I have to leave "zImage" and "zImage-3.12.10-ti2013.12.01" files in "boot" folder of root partitions on SD card to let the BBB been launched. Other files i can delete from SD card. How i can fix it and let BBB to work without SD card?

Am sorry Anton,

It should be  mmcroot=/dev/mmcblk0p2 after you poweroff & remove the sdcard & rebooting & moreover am using uboot 2014.07 & not tisdk uboot version

I'm using tisdk u-boot (u-boot-2013.10-ti2013.12.01). Options must be set like this?

bootpart=1:2
mmcroot=/dev/mmcblk0p2

It doesn't work.

Hi All, 

I'd like to join this thread, since I have encountered same problem.

this is my boot log with uEnv.txt as mmcroot=/dev/mmcblk0p2

===================================

my BBB seems not find dtb file during boot.

I have used rootfs image with tisdk-rootfs-image-am335x-evm.tar.gz of SDK v7.0 

would you please take a loot at it ?

Hi All

Finally I can boot with following uEnv.txt

==========

bootpart=1:2
mmcroot=/dev/mmcblk0p2
fdtfile=am335x-boneblack.dtb

=============

please try.

BRs,

HRJung

Yes! HRJung's "uEnv.txt" made the deal. Big thaks to all.

But i still want to know, where i can find a boot log?

And how i can make BBB to start OS from eMMC when SD Card is in device? Now it doesn't want to load system if SD Card is inserted.

Hi Anton, 

I'd like to give information about how to get boot log

please refer to chapter 7.5 of BBB_SystemReferenceManual.pdf

there is description about serial port and serial cable 

good luck.

BRs,

HRJung

Thank you for help!
