Tool/software:

Hi,

Yocto SDK: 09_01_00

EVM: AM62A SK EVM

I have booted the device from eMMC and realized that "saveenv" command is not working. I want to restore the "saveenv" command and for that I have also referred the patch:

https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1215936/tda4al-q1-there-is-no-saveenv-boot-cmd/4591095#4591095.

but the changes seem to be for FAT device and partition in the above patch.

So, which changes do I have to make to restore support of "saveenv" command for eMMC boot?

Let me know any clarification required in above query.

Regards,

Parikshit Patel

Hello Parikshit,

CONFIG_ENV_IS_IN_MMC option should save your uEnv.txt file in eMMC.

Please refer the patch:

Hi Aparna,

I have followed your suggested changes in the defconfig file but am still encountering the same issue: "Unknown command 'saveenv'". I am attaching the defconfig files here for your reference.

Additionally, we are flashing the u-env with a specific flash offset. Do we need to make any changes in the U-Boot code to specify the location from which it should find the u-env file?

Hi,

Could you check the bootpart and mmcdev variables in the following location: /board-support/ti-u-boot-2023.04+gitAUTOINC+b0d717b732-gb0d717b732/board/ti/am62ax/

I have verified the above configurations in my am62ax.env:

mmcdev=0
bootpart=0:1

which are the same as what you have suggested, but it didn't work.

Moreover, I have asked you about the u-env file. We are flashing the u-env with a specific flash offset (0x280000, raw) and it is same offset that we are using for u-boot.img. Will U-Boot be able to find the u-env file from that offset, or do we need to make changes in the U-Boot code specific for that?

Regards,

Parikshit

Hello Parikshit,

You are using DFU to flash the U-boot binaries into eMMC as mentioned in the previous thread.

So, can I assume you were successfully able to flash the u-env.txt into eMMC and use it?

The specific offsets are mentioned in:

dfu_alt_info_emmc=
	rawemmc raw 0 0x800000 mmcpart 1;
	rootfs part 0 1;
	tiboot3.bin.raw raw 0x0 0x400 mmcpart 1;
	tispl.bin.raw raw 0x400 0x1000 mmcpart 1;
	u-boot.img.raw raw 0x1400 0x2000 mmcpart 1;
	u-env.raw raw 0x3400 0x100 mmcpart 1;
	sysfw.itb.raw raw 0x3600 0x800 mmcpart 1

Could you share the output of the follwoing commands at U-boot prompt:

=> printenv mmcdev

=> printenv bootpart

=> run envboot

Regards,
Aparna

Hello,

Below is the output of the commands from U-boot prompt:

=> printenv mmcdev
mmcdev=0

=> printenv bootpart
bootpart=0:1

=> run envboot
switch to partitions #0, OK
mmc0(part 0) is current device
SD/MMC found on device 0
Failed to load 'boot.scr'
Can't set block device

Thanks Parikshit! I will replicate this on my setup and let you know by EOD.

Hello Parikshit,

I made the following config change and saveenv is restored:

=> saveenv                                                                      
Saving Environment to MMC... Writing to MMC(0)... OK

Have you been able to enable it ?

Regards,
Aparna

Hi,

I have enabled it and also shared the defconfigs with you. Could you please check if anything still needs to be removed or set in the defconfigs?

Attaching same for your reference again.

Hi Parikshit,

From what I understand, you have the config option, but unable to restore the saveenv command. Please correct me if I am interpreting this wrongly.

If the above is the case, do let me know, how are you building U-boot source code after making the CONFIG changes.

Regards,
Aparna

Hi,

I am using below commands to build U-boot:

bitbake u-boot-ti-staging -c compile -f
bitbake u-boot-ti-staging -c deploy -f

Then I am flashing tispl.bin and u-boot.img after successful build.

Regards,

Parikshit

Hi Parikshit,

Aparna will be out of office for the next few days. Please expect a response by end of this week.

Thank you for your patience.

Hi Aparna,

Any update in the case?

Hello Parikshit,

Can we verify the config changes made is actually reflected in the built images?
Could you enable debug logs to check and check if the logs are coming up additionally?

Regards,
Aparna

Hi Aparna,

Which changes are required to enable debug log at default?

Hello Parikshit,

An example to add debug statements to bootlogs:

Add the following to include debug statements in the UART console output:

#define DEBUG

to the very top (above all #include) of drivers/ram/k3-ddrss/k3_ddrss.c

Build and replace U-boot binaries

A successful boot with DEBUG messages and LPDDR4 memory will look something like this:

U-Boot SPL 2023.04-dirty (Apr 03 2024 - 16:48:03 -0500)

<boot log continues...>

Let me know if you see similar logs.

FYI, adding a print statement to any file and obtaining it in UART console should also work. We just need to confirm if your changes are getting applied.

Aparna

Hi Aparna,

I have added the #define DEBUG to k3_ddrss.c

then I have built and flashed "u-boot.img" and "tispl.bin" to board but not getting the logs that you have attached for reference. Infact getting similar logs as before.
