Hello, I'm a newbie trying out NXP products for the first time. Recently, I purchased the LS1043ARGW product and have been following the Getting Started guide. However, I'm facing issues with the "10 Booting LS1043ARGW" step, and I'm seeking assistance.

I followed the steps below:
- Connect the serial console using the USB cable to the USB port on the PC.
- Connect the AC power cord from the chassis to the local main outlet to turn on the unit.
- There is no power ON/OFF button on the unit. The power LED will blink and become solid green.
Despite following these steps, I don't see any messages on the console as indicated in "The board boots up, the console window (or the CodeWarrior IDE) shows the U-Boot messages as illustrated below."
My development environment is as follows:
- Ubuntu 18.04
- PuTTY
- Baud rate: 115200
- Data bit: 8
- Stop bit: 1
- Parity: None
- Flow control: None/XON,XOFF
Additionally, in "8 Prerequisites," it mentions, "3. Optionally, connect the CodeWarrior TAP to the LS1043ARGW. See Setting up CodeWarrior TAP for details." I'm curious if the CodeWarrior TAP is a necessary component to follow the Getting Started guide.
Thank you.
