I marked the area of interest about the jumper settings in green.
Notice the H(high on) in blue on the board.
HIGH/ON positions are to the left in RED.
Notice the L(low off) in blue on the board.
LOW/OFF positions are to the right in BABY BLUE.
GPIO_1 in Purple is on top.
GPIO_0 in Yellow is on the bottom.
This picture shows you the default manufacturer settings.
As you stated. The switches are both flipped to the right hand side meaning off.
To do the uart upload, these switches both need to be flipped to the left hand side meaning on.
Ensure you have taken out the sdcard before powering up the board to upload.
After the uard upload, these switches both need to be flipped back to the right hand side meaning off.
I hope this clarifies things a bit.
