SK-AM62A-LP: RGMII boot mode problem

Hello,

I have assigned your thread. Please expect delays due to the holidays. Feel free to ping the thread if you do not have a response within the first week of January.

Regards,

Nick

Hi Jie Li,

Until the subject matter expert is back in office, I will provide some comments.

1. I noticed that in the AM62A SDK documentation for Booting over Ethernet, there is some missing information that the AM62x SDK documentation contains. For reference, I will use the information from the AM62x SDK documentation. Have you made the Bootmode pin selections and CPSW PHY strapping as directed by the following section in the documentation?

2. There is some additional information on the Ethernet Bootloader Operation under section 5.4.5.1 in the AM62A TRM. Specifically in section 5.4.5.1.1 Ethernet Initialization Process, as suggested by the SDK documentation, Link info should be set to 1 and the attached PHY should be configured for RGMII-ID mode since the ROM does not make this configuration change during the Ethernet initialization process. 

3. I am double checking with the team on if we have an ethboot defconfig file for AM62A and will let you know when I have updates.

Best regards,

Daolin

thanks for your feedback !

Hi Daolin

Thank you for the information about link info, and i'll read through the am62x sdk documents to see if i'm missing anything

• I've checked the boot pin configuration of my board,  link info SW2.8 is 0
• I've tried to set the link info from 0 -> 1, it's doesn't work, you can see the boot pin changed after that (devstat read by u-boot)
• And I have noticed that the PHY was already working with the ROM bootloader, as the u-boot R5 spl (tiboot3.bin) was successfully loaded. If tiboot3 is not loaded, there will be no u-boot spl print log, right?
• It failed when trying to load u-boot A53 spl (tispl.bin) in my opinion
• so it seems as if something wrong in my u-boot spl configuration for eth (defconfig file) ?

Hi Jie Li,

Thanks for sharing your updates and findings. 

I checked the internal team on an ethboot defconfig for AM62A and here are the findings:

• It appears that the default SDK does not support booting over Ethernet on AM62A. That means that we don't have a reference ethboot defconfig for AM62A. 
• However, the ethboot defconfig shouldn't be too different from the AM62x version - at least for the tiboot3.bin 
• Enabling boot over Ethernet on AM62A is quite difficult to do as it involves not only defconfig changes but also changes such as (re-generating the build-in DM firmware source files to include the power domain for the CPSW3G Ethernet, allocating DMA flows back to the CPSW3G, etc).

Based on this information, it appears that trying to boot through Ethernet will be much more complicated than expected- which leads me to ask several questions to best help support you:

1. Is there a particular reason to why you need to boot through Ethernet? Have you tried other boot methods such as SD card boot? The easiest way to get started with the SK-AM62A-LP is through flashing a wic image on an SD card and booting the evm through the SD card- this method is also detailed here: https://dev.ti.com/tirex/explore/node?node=A__AQniYj7pI2aoPAFMxWtKDQ__am62ax-devtools__FUz-xrs__LATEST 

2. What is the timeline/urgency on this situation? Would you be okay with waiting until later this week or next week when the subject matter experts are back in office to provide further support?

Best regards,

Daolin

• I'm currently getting started through all the content in the processor SDK documentation on my own am62ax evm to get familiar with the am62ax processor.
• There is no specific reason for me or my customer to use ethboot mode. So it's not urgent for me to do so.
• I've already tried SDCard / eMMC / Uart / Dfu ROM boot, they work fine.
• I guess ethboot can let me only use 1 ethernet cable to boot and develop without flashing, It seems very practical, so here i am.

It would be very helpful if i could get further support on this.

Hi Jie Li,

Thanks for explaining the background of why you're booting over Ethernet.

The team had filed a request/requirement to enable Ethernet boot working out-of-the-box and to be supported by the SDK for AM62A. They are currently tracking this issue. Currently, Ethernet boot has not yet been planned for a specific upcoming SDK release but there may be more updates in next few days. 

I'll keep this thread open so that the subject matter expert can provide more inputs when he is back in office. 

I appreciate your patience on this issue!

Best regards,

Daolin

Thanks for following this topic !

Also, I'd like to know if ethboot is out-of-the-box on the am62x ?

Hi Jie Li,

Yes, booting over Ethernet should be supported by the default SDK for AM62x. You may have already seen this software documentation with details on the process: 3.1.1.3. Booting over Ethernet (Ethernet RGMII) — Processor SDK AM62x Documentation. Feel free to try it out on an AM62x EVM if you have access to one!

Best regards,

Daolin

Hi Jie Li,

We have a patch for the SDK 9.0 to enable AM62A Ethernet RGMII boot. I have attached it below. It was tested and working on SDK 9.0 and also worked on SDK 8.6. 

Please try it out and let us know if you have any additional questions/difficulties.

Subject: [PATCH] arm: k3-am62a: Add Ethernet boot support

Make the needed changes to support a full Ethernet-based boot on AM62A.
In addition to a dedicated R5 defconfig modeled after AM62 we also need
to add static device and clock data to support CPSW as it is not yet
available in the tree. Furthermore, we also need to ignore some errors
during CPWS PSIL pairing as two of the channels will throw an error
while we are trying to use them. This could be because of some left-over
ROM state that is not dealt with gracefully (by TIFS?).

Hi Daolin,

Thanks for your patch !

• I've applied this patch and rebuilt u-boot, but it still failed after tiboot3 loaded.
• I also tried with a different link info setting, same error.
• My sdk version: ti-processor-sdk-linux-edgeai-am62axx-evm-09_00_01_03.

Hi Jie Li,

After checking with the team, we realized that the patch I provided did not include (at minimum) an update to SoC auto-gen data to enable CPSW Ethernet boot. Since this is an "at minimum" change in order to enable Ethernet boot on AM62A, there might be additional changes that need to be made. 

The easiest way to get a working baseline was to create a patch with all of the most recent changes for Ethernet boot - including those we have for other SoC devices. I've attached a tarball of all patches corresponding to the most recent updates for Ethernet boot. You can ignore all the non-AM62A related patches only apply the ones related to AM62A. 

ti-u-boot-2023.04-ethernet-boot-patches-for-09.01.00.008.tar.gz

These changes were based on the SDK v9.1 U-boot sources and I have been told they were validated on AM62Ax devices (as well as other SoC devices). If these patches continue to not work on SDK v9.0 that you are using, if possible, you could try using SDK v9.1.

Please let us know if there are any additional issues

Best regards,

Daolin

Hi Daolin,

Thank you for your continued support on this topic !

although there are some git rejects when trying to patch on my SDK 9.0, but I solved them manually by checking the diffs.

I can successfully boot from ethernet after applying these patches, the boot log appears to be the same as your example.

Thank you again !
