IWR1443BOOST: EVL board does not connect to PC. IWR1443 chip overheats.

Part Number: IWR1443BOOST
Other Parts Discussed in Thread: IWR1642BOOST, IWR1443

Ordered both a IWR1443BOOST and a IWR1642BOOST evaluation boards. The IWR1642BOOST works great. Unfortunately, IWR1443BOOST is not responsive.

When powered, only the red DS2 LED lights up on the IWR1443BOOST, not yellow DS4.

The IWR1443 chip immediately gets way to hot to touch when powered on. This does not happen on the IWR1642BOOST, even when chirping.

The IWR1443BOOST will not mount, or show any response when plugged into a computer USB. We have tried multiple PC's and USB cables.

Because our IWR1642BOOST is working fine, we believe this is a hardware issue. Please help

Hi Scott,

Can you please post a picture of the setup, showing how its powered and the jumper placement?

If the COM ports are not showing when plugged in, you can try reprogramming the XDS110

Thank you

Hi Scott,

Did reprogramming the XDS110 solve the issue?

Thank you Charles for the reply.

I followed your instructions provided and those in the XDS110SupportReadMe.pdf. Even after grounding pin 97 and using the xdsdfu/reset utility, I still am not able to flash/recover the device. Are there any other steps?

Thank you

Scott

Hi Scott,

The IWR1443BOOST may have been damaged during use or setup. Can you order another board?

Were you able to get another working board? Did the problem reoccur?
