AM6548: U-boot build error

Hi Rio,

Do you build uboot from the top level makefile? Please provide your exact steps to build uboot for AM65x device.

You can also refer to below user guide:

http://software-dl.ti.com/processor-sdk-linux/esd/docs/latest/linux/Overview_Getting_Started_Guide.html#top-level-makefile

Hi Andreas:

#1. Please review my command set for building the R5/A53. in the below, is this right?

#2. I have a question:

      Why Building R5 / A53 needs to have 2 different command sets? What are the different?

#3. So, we need to use 2 commands for building R5/A53 respectively?       

      OR we need to build the R5 with 2 commands , and build A53 with 2 commands?

Please guide me how to do, thanks.

BR Rio

Still having this error while building R5...

Hi Champs:

I think the GCC version is mattering this issue, right?

The SDK6.01 is using the 7.3.1. gcc.

And this page is saying to use 8.3 gcc.

http://software-dl.ti.com/processor-sdk-linux/esd/docs/latest/linux/Release_Specific_Release_Notes.html#build-information

Am I right?

BTW, this page tells us to use the Ubuntu 18.04.

Will it work on Ubuntu 18.10?

I found 18.04 is buggy,.....

Rio,

I am working on Ubuntu 16.04 LTS, 64-bit. And I am able to build u-boot from top-level makefile with below commands;

pbotev@lin-0306:~/workdir/AM65x/ti-processor-sdk-linux-am65xx-evm-06.01.00.08$ make u-boot_clean

pbotev@lin-0306:~/workdir/AM65x/ti-processor-sdk-linux-am65xx-evm-06.01.00.08$ make u-boot

This command is automatically building uboot for R5 and A53. You can explore the makefile and build log for details.

The toolchain used for R5 is ti-processor-sdk-linux-am65xx-evm-06.01.00.08/linux-devkit/sysroots/x86_64-arago-linux/usr/bin/arm-linux-gnueabihf-gcc-8.3.0

The toolchain used for A53 is ti-processor-sdk-linux-am65xx-evm-06.01.00.08/linux-devkit/sysroots/x86_64-arago-linux/usr/bin/aarch64-linux-gnu-gcc-8.3.0

The toolchain is set in ti-processor-sdk-linux-am65xx-evm-06.01.00.08/Rules.make file.

Pavel

Hi Pavel:

Thanks for the help.

Some questions:

   #1. Do you think the SDK needs to assign this patch: https://e2e.ti.com/support/processors/f/791/t/827460?Compiler-AM3352-U-boot-build-error

         The gnu11 vs gnu99 matters with the building result I think.

   #2. Now, I'm okay to build the u-boot.

         The reason I cannot build okay is : I used the command "source /environment.setup" .... It seems we don't need to do this in the current SDK?

   #3. Can you review my build log below?

         Is this only built the R5 SBL? 

         Where is the A53 SBL It gernerated?

         Where is the output image directory ? ( I just want to double confirm).

THanks.

BR Rio

No, I do not think you need it. Just make sure you are using the correct ARM toolchain for AM65x Linux SDK, which is GCC 8.3 2019.03 hard-float.

No, you don't need.

In top-level makefile user guide we have:

http://software-dl.ti.com/processor-sdk-linux/esd/docs/latest/linux/Overview_Getting_Started_Guide.html#top-level-makefile

NOTE: You should not call this makefile with the environment-setup script sourced. The sub-component Makefiles will handle sourcing this script where appropriate, but some make targets such as the Linux kernel make target do not work properly when this script is already sourced.

Your log seems to be correct.

A53 is generated under:

ti-processor-sdk-linux-am65xx-evm-06.01.00.08/board-support/u-boot_build/a53/

R5 is generated under:

ti-processor-sdk-linux-am65xx-evm-06.01.00.08/board-support/u-boot_build/r5/

For how to use the generated files, refer to uboot user guide:

http://software-dl.ti.com/processor-sdk-linux/esd/docs/latest/linux/Foundational_Components_U-Boot.html#u-boot-for-am65x-family-of-socs

Target Images

Copy the below images to the boot partition of an SD card and boot. Instructions to format the SD card can be found here.

• tiboot3.bin from <output directory>/r5
• tispl.bin, u-boot.img from <output directory>/a53
• sysfw.itb from <path to tisdk>/board-support/prebuilt-images/

Hi Pavel:

Thanks for your clear reply, very solid.

final question:

What's the purpose of this file? ==> sysfw.itb from <path to tisdk>/board-support/prebuilt-images/

it's the DMSC used?

BR Rio

This is System Firmware. SYSFW (DMSC Firmware) on the M3 core.

Please check below user guide for details:
