AM62A7: Problems with following Linux Board Port guide for custom board

Gustav Malmstrom

Part Number: AM62A7

Hello,
I am trying to follow the guide on porting linux, Linux Board Port (ti.com)

But I have problems when following the guide.

I get these errors after adding hello-world.dts and updating the Makefile:

I need help how to solve the errors.
I am using SDK 09_01_00_07.

Hi Gustav,

The follow kernel patch should fix the build errors in kernel v6.1.

Hello,

It now builds! And the "Machine model: " Prints (and can be changed).

But I do not get to the Linux login prompt, I get this log after 'boot' in u-boot:

Do you have any leads on how to debug this?

Hi Gustav,

The problem is likely to be DDR related.

Does your board use the same DDR device as SK-AM62A? If not, did you update the U-Boot to have your DDR config updated?

0 Gustav Malmstrom over 1 year ago in reply to Bin Liu

Hello,

We are not using the same DDR device as the EVM.
But we have a previous project with the same DDR device with a copied layout. Where it is working.

We have changed the DDR included in the u-boot device tree to use our previous projects DDR config file.

We think that config should work, since it is working for that project.

Do you have any tools to test the DDR memory?

0 Bin Liu over 1 year ago in reply to Gustav Malmstrom

TI__Guru**** 169701 points

At first, what is the DDR size on your board? Does U-Boot console log report the correct DDR size?

0 Gustav Malmstrom over 1 year ago in reply to Bin Liu

Prodigy 101 points

I deleted a previous reply, I was looking at the flash part instead of the DDR...

It should be 1 GiB, we are using part K4F8E3S4HD-GUCL.

When i start the card the u-boot console log says:

SoC: AM62AX SR1.0 HS-FS
Model: Texas Instruments AM62A7 SK
DRAM: 2 GiB (effective 4 GiB)

If I change the memory in the k3-am62a7-r5.dts/k3-am62a7.dts files from:

memory@80000000 {
device_type = "memory";
/* 4G RAM */
reg = <0x00000000 0x80000000 0x00000000 0x80000000>,
<0x00000008 0x80000000 0x00000000 0x80000000>;
bootph-pre-ram;
};

If I change it to:

memory@80000000 {
device_type = "memory";
/* 4G RAM */
reg = <0x00000000 0x80000000 0x00000000 0x40000000>;
bootph-pre-ram;
};

I get:

SoC: AM62AX SR1.0 HS-FS
Model: Texas Instruments AM62A7 SK
DRAM: 1 GiB

So that looks better right?

But after letting u-boot run boot, I still get stuck:

Could it still be a DDR problem?

Hi,

Your DDR looks fine, you are booting into Linux.

Your current problem is that the kernel is trying to find the root filesystem that you requested, but can't find it.

It's looking for a partition with PARTUUID=260440ee-02, but that's not available. Have you already written the filesystem you want to boot from?

Regards,

Bas Vermeulen

Ok, good!

I created an SD card by following the instructions on the SDK and using the script bin/create-sdcard.sh as the SDK documentation described.

So i have a root and boot partition on my SD-card.

0 Bas Vermeulen over 1 year ago in reply to Gustav Malmstrom

Your linux kernel doesn't recognize your SD card, which is probably why it's not booting.

Try enabling the sdhci interfaces in your device tree, that might solve it for you.

Hi Gustav,

This kernel hello-world dts file is minimal and meant for kernel bring up, so it doesn't enable most of peripherals, including the MMC interface for the SD card. That is why your latest boot log shows kernel cannot find the rootfs on the SD card.

Please try to apply the following kernel patch to enable MMC1 interface for the SD card to see if you can boot into Linux prompt. (I didn't test this patch though.)

Hello,

Unfortunately this patch did not solve the "[ 0.947987] Waiting for root device PARTUUID=260440ee-02..." problem.

But I built a .dtb Linux file from our sister project repository that I added to the SD-card and that seems to work. I have managed to get to the Linux login prompt (and login). We have similar enough hardware that it works.

I can probably continue working from that instead of creating a new config from the hello world dtb file.

But if you have any more suggestions on what could be wrong I would be glad to try it to learn more about configuring device trees.

Hi Gustav,

Now I got a chance to test this on my SK-AM62A and figured out the proper change. Please use the following kernel dts patch instead to enable SD card.
