GPIO not working with SD

[Gautham]

Hello,

I have configured a 1 ms timer (Timer 2) interrupt. I am just updating some static variables for reference in the 1 ms interrupt. Everything seems to be working fine here (SD enabled). However I tried to toggle one of the GPIO pins in the 1 ms interrupt routine every 6 ms. Looks like this does not go well with SD. The control is in SD and is not returning to any one of my functions. I am not sure what the problem is. After this the SD stops broadcasting and nothing works. After I reset the controller via debugger it starts broadcasting and the same thing repeats.

Are there known issues in this regard? If not then can anyone let me know what might be the problem? I am not sure if I have given sufficient details. If not do let me know.

I am using: SD: 7.1 SDK 6

Thanks in advance!

What you are trying to achieve is basic and that should work otherwise there would have been a lot of reports here regarding that. I have verified this on SDK 7.2 with just one advertiser and there were no problems with the gpio. I verified even with 0.1ms timer interrupt and it just worked fine.

post your code here and I can check for you.

I am sorry for the late answer. When I try to check something, I update some example code verify and move on, I did not save that configuration. Sorry for that. I could help you if you could give me your project and I will look into it to see why the GPIO (in your case buzzer ) is not working as it should.
