PROCESSOR-SDK-AM68A: AM68A

Hi

Based on the u-boot prebuilt image date, I'm assuming you are using SDK8.6.

When you see issues with boot, does nothing come up on the console or you see any crashes? Can you please share the boot logs?

Regards

Karan

Hi.

There is no any boot message using the custom built boot binaries.

thank you.

Can you please run the below commands for the Linux SDK download directory i.e. the directory where you have board-support, Makefile, makerules etc.

1. make u-boot -j

2. cp board-support/u-boot_build/a72/u-boot.img /media/$USER/boot

3. cp board-support/u-boot_build/a72/tispl.bin /media/$USER/boot

4. cp board-support/u-boot_build/r5/tiboot3.bin /media/$USER/boot

With these images, can you see anything on the console?

Regards

Karan

1. make u-boot -j

and than I do 2, 3, 4 step

But there is no any log on the console.

I have found  something weird.

Actually I have two SDK.

ti-processor-sdk-linux-j721s2-evm-08_06_00_10-Linux-x86-Install.bin

ti-processor-sdk-linux-j721s2-evm-08_06_01_03-Linux-x86-Install.bin

currently I use the sdk-08_06_01_03 version.

The booting fails with the prebuilt boot image of the sdk-08_06_01_03.

but booting succeeds with the prebuilt boot image of the sdk-08_06_00_10.

thanks.

Hi

I will try to replicate this on my side and respond back.

Karan

Is there any progress?

Hi

I'll be able to get back to you by 20th Sep.

Karan

I am wating your reply.

Hi Coby

Apologies for the delay.

The issue is that you are trying to run the GP (General Purpose) bootloader binaries on the SK-AM68.

The SK-AM68 which has the AM68A SoC has an HS (High Security) sample. So you need to pass SOC_TYPE=hs in your build command. This should resolve your issue.

Karan

Coby

Are you not able to resolve this issue with the HS binaries as well?

Regards

Karan

Hi Karan.

I tried to build for each of three SOC_TYPE= hs, hs-fs, gp.

But  boot failed for all tiboot3.bin which I built. 

Boot succeed only with prebuilt image(tiboot3-j721s2-hs-fs-evm.bin) in the sdk-08_06_01_03.

Did you try to build and boot using the sdk-08_06_01_03?

And how can I know the SOC Type?

Regards.

Coby.

Hi Karan.

Boot succeed only with SOC_TYPE=hs-fs after I remove the question mark in the Rules.make like bellows.

SOC_TYPE ?= hs-fs  => SOC_TYPE = hs-fs

How can I know the SOC_TYPE ?

Can I chane the SOC_TYPE with gp using the board switch or changing software?

Regards.

Coby.

Hi Coby

The Starter Kit for AM68A has a high security sample, so a SOC_TYPE=gp will not work with that.

Can you please help me understand why do you need a GP build?

Regards

Karan

Hi Karan.

I was just wondering if the SoC Type is fixed or not.

You mean the SoC Type is fixed. 

Am I right?

Regards

Coby.
