So far, I can flash face_demo kfpkg into kd233 board, and run the demo greacefully.
when flashed hello_world.bin (both standalone & freertos), I couldn't see any thing on the console using Realterm.
So, what is the difference?

After messing around for awhile....
When I used openOCD with GDB, for some reason, it locks up UART0 and so there is no way I can hook up a terminal and debug. But the code execution looks ok.
My Sipeed Dan Dock arrived and I tried the same binary on that board and it works well, baudrate of 115200.
I noticed something, whenever power up both K-flash and Term cannot see the USB controller until some time later (about 10 seconds). So I am guessing there is some issue on the board that prevents me from seeing the print out during that 10 seconds delay.
The reset/boot circuitary on the eval board from Kendryte is a little different from the Sipeed Dan Dock. Will try to figure out. I am just curious if anyone managed to get it to work on their board.

@manageryzy I don't have one on hand. I don't mind purchasing, can you point me to a link to a suitable one?
Also, can you provide a hello_world.bin file? This way I know if it is due to my toolchain issue.
@mk0 do you have jtag debugger?

I am also facing the same problem. Downloading the face detect demo and it works well.
I tried to build the Hellow World from scratch and there is nothing on the terminal.
OS : Ubuntu16.04
SDK : kendryte-standalone-sdk-0.5.2
Toolchain : kendryte-toolchain-ubuntu-amd64-8.2.0
Board : K210_test_v0.2
I used Windows 10 to download the flash using flash.exe
I used Teraterm and I tried many frequencies and non will work.
After power-up the board, I connect teraterm, I then press the "RESET" button and did not see any UART print.
What baudrate is set on your PC, 115200 is correct in hello world example
