jkljkl1197 Posted March 28, 2018 Share Posted March 28, 2018 Hi, i get a probleme with the actual uart acces config by default on Uart2 (pin 32, 33), because i need to use PWM pin (use to set motor speed with a L293D) and on the board only pin 32, 33 can be use with PWM. Now i am using 32 33 pin as PWM but if the cable on these pin is connected the board doesn't boot, maybe because the uarts of u-boot use these pin and the result of un connected cable to my setup = Critical fail. When i remove the cable on pin 32 the board boot. So i need to solve that because i don't want to disconnect this cable at each start and i want to use uarts with this setup. I need to change uart2 to uart1 or find a way to get PWM or a other pin option where it can be use with a L293D to set motor speed. Thx guy's have a nice day.

TonyMac32 Posted March 30, 2018 Share Posted March 30, 2018 Opening a request for feedback on this one, I would change it immediately, but others may have designed around the current reality. 1 Link to comment Share on other sites More sharing options...
