[SOLVED] EK-TM4C123GXL Hibernation Mode

[mekitron]

Hello,

I am using TI's EK-TM4C123GXL kit for my projects which should go in hibernation mode when SW1 and SW2 are pressed together, but it doesn't.

Any idea why hibernation mode is not working for me?

Thanks.

The EK-TM4C123 will support the VDD3ON mode of Hibernate, make sure that VDD3ON being set in Hibernate Control Register.

ud,

Thank you for your reply.

I haven't written any code. I am just following Tiva Wiki page to get launchpad working. If you watch the video then at sixth minute, you'll see that Scott Bland is teaching how to hibernate MCU and increase/decrease the intensity of RGB LED. This is what exactly, I am trying to do but both operations are not working for me, though it changes the colour spectrum when I press SW1. Moreover my launchpad's LED flashes quite faster than in the video.

Did you get me? And, may you tell me how to set VDD3ON mode to hibernate the launchpad?

I don't know weather you did the led code modification mentioned in the link you provided .If you did then it should work.for VDD3ON look at the above links.

Thank you for your help ud.

I have solved the problem by myself. In one of my previous program, I just disabled hibernation mode accidentally and was not aware of it. I restored the binaries and now it is working very well.
