i'm using stm32l4r9 discovery kit and the built in led of stm32l4r9 discovery kit works but led attached to other gpios don't work. no mater if i set or rest it.

On the documentation it states d13 as PB13?
the positive leg of the led is attached to 3.3v and the negative to d13 i just added a resistor equal to r5 on between ground and negative le and its working now

Hello @kanuz_khan, welcome to ST Community, 

That's probably a wiring issue! Also, check if the GPIO you're using as configured correctly as output pins

Hello @kanuz_khan 

Could you please specify which LEDs attached to other GPIOs you are talking about? LEDs you connected externally or what? which GPIOs? How did you connect the LEDs? 

Please provide more details and if possible your schematics.

Thank you.

i've added the code of main file in the replies

 i'm using ph4 and gpio_8

i've checked the wiring it works fine when i attach it to vcc

i connected the gnd of led to gnd next to d13 and positive to d13 i.e gpio 8

Hello,

I don't see GPIOH pin 4 configuration in your code.

Also when you say "gpio 8" which GPIO you are referring to? PD8? PD8 is connected to an SRAM!
