Delay problem in M4 GPIO program

link text
We are working on M4 GPIO pins. When trying to switch ON and OFF the Led.

We are not able switch off the led. The LED is continuously ON.

@narayanamohan: Could you point out the code you are using to switch the gpio in your zip-file?

Dear Jaski,
Kindly go to location in folder

The compiled file blinking_imx_demo.elf is also linked.


I checked your code.

First of all, the delay in at line 145main.c is set as a real value, this should be set as uint32 value. Secondly, you are changing all the time output with a delay of 100ms, so you will never see the changes. Please set the gpio output to a fix value and then measure the voltage at the output of the Pin you changed.

Best regards, Jaski
