PROCESSOR-SDK-AM64X: u-boot changes to save environment values to root fs in eMMC

Abin Raj

Hi, I have my TMDS64GPEVM set up with tiboot3.bin, tispl.bin and u-boot.img in OSPI and the Linux root fs in eMMC. The eMMC partiton is shown below:

mmc partitoin

I havent been able to update the environment values after flashing the eMMC with the Linux rfs.

I have looked around and found that the am64x_evm_a53_defconfig has CONFIG_ENV_IS_IN_FAT=y and CONFIG_ENV_FAT_DEVICE_AND_PART="1:1" enabled to save env values to FAT partition in SD card.

Since I am looking to save the env values in eMMC, I have commented out the same and added the following:

CONFIG_ENV_IS_IN_EXT4=y
CONFIG_ENV_EXT4_INTERFACE="mmc"
CONFIG_ENV_EXT4_DEVICE_AND_PART="0:1"
CONFIG_ENV_EXT4_FILE="/boot/uEnv.txt"

But this throws the following error while trying to build u-boot:

There's an earlier e2e post on "saveenv" to eMMC on AM57xx device.
e2e.ti.com/.../am5718-saveenv-error-when-booting-emmc
Will you have a look at it to see if it helps on your setup?

Thank you for the reply Hong Guan64

I have already commented "CONFIG_ENV_IS_IN_FAT" in the am64x_evm_a53_defconfig file.

Further more, just to check if that change alone works, I have removed the additional 4 entries that I have added for saving it in eMMC. This builds the u-boot without the "saveenv" command. I am guessing there might be some version changes between the two cases.

Hi Abin,
I tested using SDK 7.3.0 on AM64x EVM, and I'm attaching the two log files for your reference:
- am6_7.3.0_eMMC_booting.txt: booting from eMMC
- am6_7.3.0_MMC_booting.txt: booting from MMC
From two log files, it looks like "saveenv" is saving to eMMC.
=> saveenv
Saving Environment to MMC... Writing to MMC(0)... OK

Have you tried SDK 7.3.0?

I am using the am64x_07.03.01.006 SDK. The v07.03.00.02 from the shared link is not getting downloaded. I am still able to download the v07.03.01.006 though.

Could you kindly check if it works in the newer version ?

Also could you share the changed defconfig so that I can check if I have missed anything ?

Hi Abin,
I tested using SDK 7.3.1, and it seems there's difference on "saveenv" from SDK 7.3.0
I made a quick change on SDK 7.3.1 (in attachment), and I'm attaching the two log files with the new changes:
- am6_7.3.1_env_eMMC_booting.txt: booting from eMMC
- am6_7.3.1_env_MMC_booting.txt: booting from MMC

I'm checking with internal release team on your reported issue of downloading SDK 7.3.0, and will keep you posted.
Best,
-Hong

Thanks Hong Guan64. With these changes I was able to save the env in eMMC.

Just to make things clear, could you share where the updated env gets stored ?

With these changes (CONFIG_ENV_IS_IN_EXT4=y, CONFIG_ENV_EXT4_INTERFACE="mmc", CONFIG_ENV_EXT4_DEVICE_AND_PART="0:1", CONFIG_ENV_EXT4_FILE="/boot/uEnv.txt") I was trying to instruct u-boot to change env and save to uEnv.txt in the /boot of the Linux partition. With the new u-boot changes I cant seem to find where this is saved in the eMMC.

Hi Abin,
I'm attaching the log file I captured running the following u-boot cmds from eMMC booting using SDK 7.3.1 on AM64x EVM.

pri vendor
setenv vendor ti_test
pri vendor
saveenv
reset
pri vendor

where "saveenv" cmd saves environment variables to eMMC boot0 partition starting @0x3400 (refer to "eMMC layout" in software-dl.ti.com/.../UG-Memory.html
For testing purpose, reading u-boot environment variables using u-boot cmds is listed below (also in the attached log file):

mmc dev 0 1
mmc read ${loadaddr} 0x3400 0x100
md.b ${loadaddr} 0xd00

Best,
