Is this error resolvable, or does it indicate a damaged board? What logs could be provided to come to a conclusion?

Hi,

Is your board in debug mode? Or functional mode? I assume you've made no changes to the software?

Best,

Nate

The device is in functional mode, only SOP0 is bridged.

I've made no changes to the software, I've loaded the xwr16xx_mmw_demo.bin with UNIFLASH from the 02_01 SDK.

The DS1 is not lit (which the manual says would indicate a hardware error).

Pressing the NRST, causes the message to repeat in the console.

Hi,

Can you confirm your chip is ES2.0 silicon and not ES1.0 silicon? You will have to read from the part number on top of the chip. Please refer to https://www.ti.com/lit/ds/symlink/iwr1642.pdf and see what "PG Revision" your part is.

Regards,

Tim

Ah, I think it might be ES1.0 silicon. What does this mean for the SDK I can use? I've attached an image of the radar module.
