Inquiry about how to operate the board
Hello.
Today, I received your SDK board ( KLM730A300A)
To verify the operation after receiving the board,
I connected the UART to the board and checked the output via terminal (Putty).
However, the board outputs garbage data at the beginning, and then remains in a state where the characters I input are displayed exactly as they are. Of course, the Baudrate was set to 115200 without any issues. Also I cannot enter the U-boot.
Is the firmware pre-installed on the EVM board at the time of shipment?
Or do I have to install it myself?
There is no installation guide in your manual. (KL730 Series Evaluation Module User Manual )
Are there any documents I can refer to?
Thank you!

Hi,
Yes, the firmware is pre-installed on the EVM board. The UART issue could be caused by incorrect UART connection or incorrect configuration.
There are more documents available on our Development Center, at the KLX730 SDK section: Developers | Kneron – Full Stack Edge AI
There is a KL730_Development_Environment_User_Guide.pdf inside SDK/01_BSP/01_Document, which would have helpful information such as UART configuration.
Hello.
I checked the UART configuration in the KL730_Development_Environment_User_Guide.pdf document and configured it accordingly.
However, no message is being displayed.
If the firmware is pre-installed, could the Boot mode be the problem?
What else should I check?
Thank you!
Hi,
The boot mode could be the problem. Please check the switches on the EVM and flip them to the boot mode you prefer.
If boot mode isn't the cause, it could also be a problem with the UART cable. Could you try the following? Thank you!
-Disconnect the cable and connect it again
-Use other UART cables instead
-Make sure the Rx and Tx cables are connected to the correct places
