SK-AM62B-P1: Check if it is HS FS device or not

Raj Kumar

Part Number: SK-AM62B-P1

Tool/software:

Hi Team,

I’m trying to run the Python script located in boot (boot_socid_parser.py). My data.txt file provides a binary indicating whether the device is in HS or FS mode, and I believe I need to run this script to decrypt it. However, when I attempt to run the script, I get an “invalid port” or “port is busy” error.

I suspect the port is busy because I previously initialized UART boot mode and was able to receive characters. I’m stuck at this step and can’t determine whether it’s an HS or FS device.

Could you please help me resolve the “port busy” or “invalid port” issue? I can see characters in the Code Composer Studio serial terminal. For reference, I’m running Ubuntu 22.04, and Code Composer Studio is also installed on Ubuntu 22.04.

Hi Raj,

Could you try these steps to determine the device type -

Hey Johnson,

I reviewed the document and understand the expected output. My main concern is this: even after I disconnect the serial terminal, the port appears free, but when the Python script calls the serial API, it still falls into the try-except block and prints “invalid port” or “port is busy.” I’m not migrating from GP to HS FS, but I need to detect whether the device is HS FS or GP. If it’s HS FS, I must add the keys to match the image; if it’s GP, no extra action is necessary. Can you guide me through the steps to troubleshoot the port issue when running the Python script?
