Linux/AM3351: Flashing Uboot-kernel on EMMC & uSD card

Apurva Ankleshwaria89

Part Number: AM3351
Other Parts Discussed in Thread: UNIFLASH

Tool/software: Linux

Hi,

I have a AM3351 custom board. I have made changes in U-boot and Kernel for my custom board. Also, flashed U-boot through UART. In U-boot, I am able to detect both EMMC and uSD card on my board. As next step, I am trying to flash u-boot, kernel, file system through Uniflash using EMAC1(in boot sequence). However, the flashing is not progressing beyond 0%. Any leads on this issue?

Also, i have a uSD card connector on the board. Can someone direct me to a relevant TI wiki link on how to partition and flash the code on uSD card for it to be bootable. Thank you!

Hi,

After I changed the file names from u-boot.img to u-boot-restore.img and u-boot-spl.bin to u-boot-spl-restore.bin, I was able to proceed with the flash on Uniflash. However, it got stuck somewhere after proceeding further. Attaching UART logs. Any leads on the issue?

Thank you!

Apurva,

Based on the log, I believe you need to modify your U-Boot bootcmd to do boot from the network. It seems the code is trying several paths that never fully succeed.

Once you get to the kernel, how do you have it configured to do the flashing? All Uniflash does is serve files and try to track progress. Your application really has to be configured to do the necessary flashing operations.

For setting up the SD Card, I would use the sdcard-create.sh script in the /bin folder of the SDK as a reference.

I hope this is helpful to you.

Hi Ron,

Thanks for your response.

Is this part of /include/configs/am335x_evm.h file? What changes should I make for network boot?

RonB said:

I only made changes in am335x_boneblack.dts file relevant for my custom board. Apart from this, I haven't made any change to support flashing operation in kernel. Kindly point me to a relevant TI wiki

I am new to this. Kindly point me to a relevant TI wiki on how to use this script.

Thank you very much!

Hi Ron,

Also, please direct me to patches which enable seamless communication between Uniflash and target.

Apurva,

I'm sorry, we do not provide patches as we consider this part your system design as many steps are dependent on your system goals.

For the SD Card script, our documentation is here:

software-dl.ti.com/.../Overview_Getting_Started_Guide.html

This will tell you how to run the script to create an SD card from a computer. You can use this script as a guide on what needs to be done to properly set up an eMMC as well. Basically, you need to partition and format the drive then copy files over. The script will provide exact commands and ordering that should be helpful.

Since you have made no other changes to Linux, you do not have a valid filesystem for Linux to mount as typically the SD Card or NFS is used to mount a filesystem. You can also use an initramfs which is common for flashing.

Please see:

processors.wiki.ti.com/.../Sitara_Linux_Program_the_eMMC_on_Beaglebone_Black

This guide is a bit out of date and I am in the process of updating this document, but it should provide a good overview of the overall process you'll need to get through. You can ignore the patches that it is referring to as they are not longer needed for recent SDKs.

The commands referenced below are the correct way to TFTP boot from the kernel once you have the filesystem issue resolved. These can all be run from a U-Boot prompt and should get you to a kernel:

dhcp
run findfdt
tftp ${fdtaddr} ${fdtfile}
bootz ${loadaddr} - ${fdtaddr}

I hope this is helpful to you.

Thank you.

Apurva,

OK, thanks for clarifying. Could you please provide a full capture of running this script. I need to see how you've set it up and the options you are passing it to see where it is going wrong.

Also note that this script is developed for programming a SD card from a PC and has not been tested for this use case. It may very well need some adaptations to use it on the target to program an eMMC.

Apurva,

Thank you for the detailed log. Just to clarify, you are now trying to create a bootable SD Card from a Linux PC? I am assuming this is true...

I went through this myself just now and was not able to reproduce what you are seeing. Here's what you see as the first error:

As you can see, the difference seems to be in the tar command to decompress the boot partition. Here's the command I used to create mine:

tar cfJ bootpart.tar.xz MLO u-boot.img

Maybe you can compare it to the one you used or try this one?

I hope this helps.

Hi Ron,

I was able to flash the SD card this time with the change in tar command you mentioned. Thanks for providing that.

Once flashed, I am trying to boot my board through SD card(MMC0 is part of boot sequence) and I am getting following logs on UART. The kernel is hanged at the last line. Kindly check and let me know your thoughts. Thank you!!

Apurva,

Please notice this from your U-Boot output:

Apurva Ankleshwaria89 said:
## Error: "mmcargs" not defined

This is coming from your Uenv.txt, I believe. It is not setting up the Kernel command line properly for MMC boot.

Apurva Ankleshwaria89 said:
[ 0.000000] Kernel command line: console=ttyO0,115200n8 root= rootfstype=ext4 rootwait

Here's what I'm using for a successful boot:

console=ttyO0,115200n8 root=PARTUUID=0001292c-02 rw rootfstype=ext4 rootwait

I think your issue is with "root" being populated correctly with the UUID of the SD Card rootfs partition.

I hope this helps you.

Hi Ron,

Thanks for the input. This worked for booting through SD card.

Now, I am trying to boot through eMMC. Once kernel was loaded through SD card, I mount the eMMC and then created boot and rootfs partitions and copied the files on eMMC. Post, I remove the SD card and try to boot through eMMC. I am able to load SPL and U-boot, however not able to load kernel through eMMC. Attached UART logs and uEnv.txt file. Kindly let me know your thoughts.

Apurva,

From the logs it looks like your eMMC is on MMC1. Can you stop the boot at a U-Boot prompt and use mmc commands (help mmc at prompt) to learn more about the setup on a live board. Then, from this, see if you can use setenv to setup the environment appropriately to boot? If so, you can save that setup using saveenv.

I don't believe you are ever loading uEnv.txt at this point.

Hi Ron,

I was able to start loading of kernel from eMMC as well. However, the loading had an error and stopped in between. The kernel image is the same that i am using for SD card. However, in SD card, kernel is loading. Not able to understand the reason. Kindly look at the the logs and let me know your thoughts. Thanks

Apurva,

This looks like a mismatch between you customized filesystem's init and the filesystem that is mounted on the eMMC. I would compare the SD Card and eMMC contents to see if there are any differences.

I'm sorry, we can't help debug the customized FS. You might try the FS that comes with the SDK just to see if there are any differences.

For example, I don't see messages like:

You are in emergency mode. After logging in, type "journalctl -xb" to view
system logs, "systemctl reboot" to reboot, "systemctl default" or ^D to boot
into default mode.
Press Enter for maintenance

in the standard Arago FS.
