TE0720-03-1CFA on TE0703-06 carrier SD boot hangs

[dyne21]

Hello,

The SD boot images were built and tried as below. SD boot doesn't show any progress on the terminal.
Btw, the prebuilt boot_images under "1cf_1gb/hello_te0720" prints "Hello Trenz Module(TE0720)" on the terminal.
The other prebuilt boot_images under "1cf_1gb/u-boot" doesn't print anything on the terminal.

Thanks,
Jeff

Hi dyne,

first i would recommend to get the board to boot up with the prebuilt files.
Follow this documentation -> https://wiki.trenz-electronic.de/display/PD/TE0720+Test+Board

In general, just run the setup script from the project main directory and generate the prebuilt binaries after choosing your module from the list.
The binary folder should open up with all necessary files (Boot.bin,boot.scr, image.ub ...).
Copy the files from the boot_linux folder to a formatted sd card and plug it into your carrier.
Open a terminal with baudrate 115200 and you should see the boot prints.

best regards

Hi Waldi,

Thank you for the answer. The prebuilt image can boot the board w/o problem.
The BOOT.bin was created again with Vitis. It starts showing some messages on the terminal as below but it's the end.
I tried petalinux-build again with configuration changes as below link but I see the attached build errors. Could you help me to solve the errors?

Thanks.

Hi,
did you create the Boot.bin with the tcl command "TE::sw_run_vitis -all" ? described under Design Flow, if you use the reference design.
Design Flow - step 5. -> If you use the provided petalinux template and the xsa file, you should be able to build petalinux without errors.
From there you can apply your changes to the vivado project, generate a new xsa and again import it to the petalinux project. If that fails there is probably something wrong with the vivado hardware design or you made some errors in the petalinux project.

unfortunately petalinux error messages are not always very obvious of what the actual cause of failure is ...

regarding your boot prints, its stuck before uboot starts to be executed. But since you didnt manage to successfully build linux, what files did you put on the sd card to boot?
I always recommend to go through the design flow with our provided reference design and if that works, try to apply your changes.

Hi Waldi,

I entered "TE::sw_run_vitis -all" command on Vivado TCL window. I'm not clear about "use TE Template from "<project folder>\os\petalinux" of step 5 in design flow. How to use "TE Template" from petalinux?

Regarding the boot prints, other images except BOOT.bin were created by petalinux-build without the configuration modification.

Thanks.

[Waldi3141]

in the reference design - test_board folder there is a folder "os". This is pretty much a preconfigured petalinux project with all necessary settings for the design. Use it and copy the xsa file into it. run "petalinux-config --get-hw-description" and "petalinux-build".
As described in step 7. after the successful petalinux build you need to copy the stated files from the petalinux project to the prebuilt folder in the reference design and run "TE::sw_run_vitis -all" in vivado , thats what creates a new boot.bin in the prebuilt directory

Hi,

The folder "TE0720-test_board-vivado_2021.2-build_11_20220202131818/test_board/os/petalinux" doesn't include settings.sh script.
So, petalinux-* commands can't work under the folder. Can I copy the script file from another petalinux folder?

Thanks.

Hi,

have you tried something like

source /tools/Xilinx/PetaLinux/2021.2/settings.sh

Best regards,

Hi,

I tried to use "test_board/os/petalinux" as a project folder. The "/home/ubuntu/petalinux" folder was used just as a tool for compilation.
However, I still don't see u-boot prompt. The FSBL log is the end. I wrote down all the steps below. Please help what else I have to do.

Hi,

TE::sw_run_vitis -all generates the BOOT.bin file usually in folder

"<project folder>\prebuilt\boot_images\<shortname>\u-boot". In your case it should be saved somewhere called

"/home/ubuntu/TE0720-test_board-vivado_2021.2-build_11_20220202131818/test_board/prebuilt/boot_images\1cf_1gb\u-boot"

Have you checked that?

Best regards,
Manuela

Hi,

The image under "test_board/prebuilt/boot_images/1cf_1gb/u-boot" generated by "TE::sw_run_vitis -all" works well for SD booting. I didn't have to generate it with the Vitis fsbl project.

Thanks.
