Hello,
On my vex controller, when I turn the robot on, both the battery power and program status leds light up. Thats not the main problem, though. The vex won’t download anything, including firmware. I’ve tried different usb cables and battery packs, none of which work. the circuit looks fine on the inside, but im not exactly the professional for circuitry.
Physical Overview: blinking power led and on program status led
Software Overview: will not download, including firmware on multiple cables
