AM5728: DTS file for AM5728

Part Number: AM5728
Other Parts Discussed in Thread: AM3359

Hi Ti Team,

I am working on the AM5728EVM board. I've already worked on AM3359. But I'm not clear about AM5728's both uboot and kernel builds. What compiler can I use for the build process? in that SDK user guide they mentioned

make ARCH=arm64 CROSS_COMPILE=aarch64-none-linux-gnu-distclean

I got the below error when I tried the above compiler:




And I referred to the below thread.
https://e2e.ti.com/support/processors-group/processors/f/processors-forum/813302/linux-am5728-how-to-build-kernel-source

They built the kernel using arm CROSS_COMPILE=arm-linux-gnueabihf-i, which was successfully built using the above compiler.
Please tell me which compiler we need to use.
one more doubt,
What defconfig and dts files were used to build the kernel for both the AM5728EVM board (TMDSEVM572X) and the AM5728 processor?
Thanks in advance.

Hello Priyadharshini,

What SDK are you working with?

If you are working with the latest, please look at the SDK guide Getting Started:

Processor SDK Linux for AM57X 08_02_01_00 for further guidance.

The compiler is within the SDK in the linux-devkit forder. You can use the following command to add it to the PATH environment variable:

export PATH=<sdk path>/linux-devkit/sysroots/x86_64-arago-linux/usr/bin:$PATH


If you open the Rules.make file you can see the standard defconfigs that are used:



This should apply to earlier SDKs as well!

Happy coding.

Priyadharshini,

For DTBs see:

Linux: ti-processor-sdk-linux-am57xx-evm-08_02_01_00/board-support/linux-5.10.100+gitAUTOINC+7a7a3af903-g7a7a3af903/arch/arm/boot/dts

u-boot: ti-processor-sdk-linux-am57xx-evm-08_02_01_00/board-support/linux-5.10.100+gitAUTOINC+7a7a3af903-g7a7a3af903/arch/arm/boot/dts

You can do a list to grep to find the DTS that corresponds.

Hi Josue Zamitiz-Ayala,

Thanks for your response.

I want to enable GPMC on my custom board, so I need to work with AM5728EVM's GPMC in the device tree. Please tell me how to configure GPMC in the device tree.

Regards,

Priyadharshini.
