HI,

Can you please share a picture of your setup?

Hi,

Sorry one more question. Do you know if you have IWR6843 ES1.0 or ES2.0. The steps you are referring to in e2e have been tested on ES2.0.

Thanks

Yogesh

Hi Yogesh,

 I have IWR6843  ES2.0. 

Thanks

Hi,

Please modify mmwaveconfig.txt:

IsFlashConnected=0;

Let me know if this resolves the issue.

Thanks

Yogesh

Hi Yogesh,

I have tried your method, but the problem still exists. See the attached picture please.

Thanks.

Hi,

Now the only reason that I can think of is, if the flash is not completely disconnected and it is not falling to SPI boot mode.

Thanks

Yogesh
