SK-AM62: Test USB using devmem2, but get "Bus error" message

Part Number: SK-AM62

Hi Ti Support Team,

We are going to test USB on AM62-SK EVM.

We use the way as below:

USB1:

devmem2 0x31100420 w 0xA0
devmem2 0x31100020 w 0x4
devmem2 0x31100424 w 0x40000000

Step #1, #2 work well, but #3 returns “Bus error” message.

We also give a try for USB0, but get the same result.

Why do I get the "Bus error" after #3 manipulation?

Please refer to the attached log file, USB_TEST_20230705.log

Hi Kylix,

> root@Triton:~# [ 36.242925] usb 1-1: USB disconnect, device number 2

You should run these 3 devmem2 commands without any USB device attached to the SK-AM62 USB port.

Hi Bin,

Thanks for your assistance.

The below is the screenshot of running all manipulations without any USB device attached to the SK-AM62 USB port.

It still shows "Bus error" after executing #3 manipulation.

The below is the screenshot of dmesg command shown only for usb:

Is there any preparation before manipulating all devmem2 commands?

Thanks.

Hi Kylix,

I have the following message in kernel boot log:

[ 6.259573] usb usb2: Manufacturer: Linux 5.10.168-g2c23e6c538 xhci-hcd

but yours has "*ecs-triton*". Do you use TI Processor SDK for SK-AM62 in your test?

Hi Bin,

"ecs-triton" within Linux-5.10.168-g2c23e6c538 string is the additional word only for our currently project.
Will it affect the USB testing using devmem2?

Thanks.

Hi Kylix,

The string itself won't affect any kernel function. I just wanted to check if you use the same kernel source as that in the SDK, and the next question would be if you built the kernel with the same defconfig as provided in the SDK. Basically trying to understand if there is anything changed in your kernel which causes this BUS error problem, as I don't see it on my SK-AM62 with prebuilt in the SDK.

Please try the SDK prebuilt on your board to see if you can see the same issue too.

Hi Bin,

I use tisdk-default-image-am62xx-evm.wic prebuilt from the SDK on my SK-AM62 EVM,
and execute 3 commands of testing USB.
Get the result as below:

At #3 still shows "Bus error"

The below is the log of executing 3 commands after flashing .wic into microSD and then 1st booting.

I get the source code of devmem and build it in aarch64.

And I also use this version of devmem to execute 3 commands.
But still get the same result as the previous one.

Thanks.

Hi Bin,

I find that tisdk-default-image-am62xx-evm.wic prebuilt from the SDK has consisted of devmem, and it works well without "Bus error"

Thanks for your assistance
