Can't upload my sketches to arduino uno

Using Arduino IDE 1.x
1

I have a project to build a quadruped using 8 servos sg90.
However I have a problem where I can't upload my sketch to my arduino if i connect all of the servos to arduino pin. But if i disconnected all of the servos, then the uploading work fine. I use a pcb board to connect the servos to the arduino. I don't know why this is happen, the board seems to be correct, and it's annoying when I must disconnect and connect all the time everytime I upload the new sketch. This is attachment of my board, and the code i used. hope you all can help me, sorry for my bad english.

thank you.

If you have pins 0 and 1 connected to servos they can't be used for serial upload. You should use different pins for those two servos.
