Serial Sync Timeout even when pressing RST

[mjadiahmed]

Hello, thank you for the repo, I have a problem, it keeps showing
"please manually reset the device.
.......................................................
serial sync timeout."

even after I click on Reset, the programming doesn't start. any idea ? I'm using wm801 board V1.1.

N;B: when I use the code with arduino IDE, I can program it without pressing on RST, and works smoothly. here is the link to Arduino IDE variant : https://github.com/Hi-LinkDuino/w80x_arduino
So I mean there is no physical problem with the board.

Thank you.
