PROCESSOR-SDK-AM62X: Wifi is not enabling in the am62x E3 evalution board and from putty noyt taking the commands to stop the U-boot

raj kumar

Tool/software:

Dear Sir,

I am currently working on the AM62x E3 Evolution Board, specifically with the AM6254 processor, and I’ve encountered a couple of issues that I need assistance with:

1. UART Input Issue:

I have successfully loaded the OS onto the board, and the kernel loading prints are visible in Tera Term.
However, the board is not accepting any input from my laptop’s keyboard. I am attempting to stop at U-Boot by pressing keys, but the input is not recognized.
I suspect this may be related to a Device Tree Source (DTS) configuration, but I am unsure of the exact cause or solution.

2. Wi-Fi Connectivity Issue:

After loading the OS, I noticed that Wi-Fi is not showing up as expected.
When running the #ifconfig command, the wlan0 interface is listed, but it fails to connect to any network.
I have verified that the Wi-Fi hardware is functioning, so I believe this could also be a configuration issue.
Could you please provide guidance on resolving these issues? Any insights into possible DTS misconfigurations or additional steps I should take to troubleshoot the Wi-Fi connectivity would be greatly appreciated.

Thank you for your support.

Best regards

Hi,

For WiFi, please create another thread and we will only focus on UART debug for the current thread.

Please ensure hardware flowcontrol and software control configuration in Tera Term is disabled.

Hi ,

Thanks for the response, i have disabled the hardware and software flow control still getting the same issue , i have tried with different methods also still gettig same issue, i have doubt on the DTBs file and pin muxing, is there any chance for that.

Best Regards

Hi Raj,

If you didn't modify the pinmux in devicetree, the pinmux shouldn't be the issue. The Processor SDK prebuilt SD card WIC image should boot properly on the EVMs.

If the UART flow control is not the issue, have you tried with different USB cable?

Hi Raj,

If the UART connection is good, there is no any other reason besides UART flow control setting which could prevent the board to received characters from the PC.

Can you please try to test with a different PC? Preferably a Linux PC.
