SK-AM64B: U-Boot SPL: No Ethernet Found

Hello Joachim, 

Joachim Wiesemann said:

BOOP server and TFTP are working and the tiboot3.bin from the Linux SDK is started

What SDK version are you using?

Have you built the U-boot binaries (tiboot3.bin, tispl.bin, u-boot.img) without errors? 

What are your boot switch settings?

Which ethernet port are you using on the SK AM64B EVM?

https://software-dl.ti.com/processor-sdk-linux/esd/AM64X/09_02_01_10/exports/docs/linux/Foundational_Components/U-Boot/UG-Network-K3.html 

Can you do a Wireshark capture on the host PC ethernet port to see what shows up when the error message shows up?

Hi Daolin,

What SDK version are you using?

09.02.01.10

Have you built the U-boot binaries (tiboot3.bin, tispl.bin, u-boot.img) without errors? 

Yes

What are your boot switch settings?

Primary Bootmode = Ethernet (0100)

Primary Boot Media = (111)

Backup Bootmode = None (000)

Which ethernet port are you using on the SK AM64B EVM?

RJ45 Connector 2, the BOOTP protocoll wouldn't work otherwise.

Can you do a Wireshark capture on the host PC ethernet port to see what shows up when the error message shows up?

I will make a capture (I didn't save the last one) und upload it. It showed the BOOTP Pakets from and to the device and then TFTP transfering the tiboot3.img file.

Best regards,
Joachim

How can I upload the .pcapng file from wireshark? When I drag it into the edit window it uploads and then it vanishes.

Hi Joachim,

Thanks for sharing the above details.

I currently only have an SK-AM64 GP EVM instead of SK-AM64B. I was able to test on SK-AM64 GP EVM and also found only tiboot3.bin was transferred by looking at my Wireshark capture; however, I did not get an output on the console. The main difference between SK-AM64 GP and SK-AM64B is a different tiboot3.bin. Since both your results and my test results show that tiboot3.bin was transferred, I think there might be something wrong with either the tispl.bin binary and/or perhaps the PHY is not being found. 

I'll raise a bug report on this, but a fix would be on an upcoming SDK 10.x

-Daolin

Hi Daolin,

I will give that a try.

My current guess is that the SPL is always build for EVM even if you set the platform to SK EVM and thus uses the wrong device tree / defconfig.

See Rules.make lines 61 ff.

Joachim

Hi Joachim,

>>>However, with the most recently released SDK 10.00.07.04, by adding the following to the am64x_evm_r5_defconfig, you should be able to get Ethernet boot working.

Any progress on testing this out?

>>>My current guess is that the SPL is always build for EVM even if you set the platform to SK EVM and thus uses the wrong device tree / defconfig.

I believe that the defconfig file for the AM64x EVM and SK-AM64x should be shared/the same between the two. Have you tried changing the device tree specified in Rules.make to the sk dts and see if that changed anything?

-Daolin

Hi Daolin,

I was a little distracted by a second project but will resume this one in about two weeks. I will report the result here.

Joachim

Hi Joachim,

No problem, thanks for the update

-Daolin

Hello everybody,

I am facing the same problem as Joachim.
I installed SDK v10.00.07.04 and after editing am64x_evm_r5_defconfig adding CONFIG_NET_RANDOM_ETHADDR=y, I was finally able to get into U-Boot.
Anyway the dtb/Linux loading process keeps on failing. Here's the log I get:

How can I make u-boot properly launch Linux?

Hi Federico,

Can you make a separate E2E thread on your specific issue?

We want to keep each thread isolated to one particular issue for easier searchability/traceability in the future.
