IWR1642BOOST: my device is stopped working, I don't know what just happened

Pranav Venu,

       Could you please elaborate on what do you mean by stopped working? 

Were you able to run out of box demo application?  

Thanks and regards,

hi Chethan,

Initially, I tried to flash the code to the device by using uniflash then I failed. Then I found that COM ports are missed from the device manager. Then I installed a new xds package but I didn't find the COM ports on the device manager.  Then I asked help in e2e and they give this solution http://dev.ti.com/tirex/explore/node?node=ALFqIj4dX6S.TZRERoSphA__FUz-xrs__LATEST  and I tried to flash the new bootloader to the device but after sometimes its LEDs stopped blinking. 

I checked the adapter and that is working fine. I don't know what just happened to my device? How can I troubleshoot the hardware?

Pranav Venu,

       I do see you have another thread in the below link

     https://e2e.ti.com/support/sensors/f/1023/t/868211

 Could you please confirm what response did you get when you perform below steps:

Xdsdfu.exe -b boot_loader.bin –r

Xdsdfu.exe -f firmware.bin –r

Did you get any error? 

Thanks and regards,

Hi Chethan, 

I tried to flash the bootloader based on this http://dev.ti.com/tirex/explore/node?node=ALFqIj4dX6S.TZRERoSphA__FUz-xrs__LATEST 

But I tried to ground the TD0 pin to ground. Then suddenly the device stopped working (all of its LEDs turned off).

Hi Chethan,

First I reinstalled the windows device drivers based on this link http://dev.ti.com/tirex/explore/node?node=ALFqIj4dX6S.TZRERoSphA__FUz-xrs__LATEST

but I didn't find the COM ports on device manager then I decided to flash a new bootloader to the device and

I found the following (marked red)

That's why I connected TD0 pin to the ground. 

For me, it's difficult to troubleshoot the hardware, and it is very expensive to buy a new 300 dollar device again. What should I do?

Pranav Venu,

     Thanks for the clarification, TDO pin you have referenced is,  TDO pin of the XDS110 TM4C1294NCPDT device (pin 97 of the 128-pin package device) not the mmWave sensor TDO pin. 

In 1642boost board TDO pins are not brought out of package boundary, Hence it is not easy to access it. It could be possible during this process there could be damage to TM4C1294NCPDT device.

Without trouble shooting from the Hardware bring up section it would be difficult to support it. 

Also for flashing the new boot loader you need to follow below steps for XDS110 device, Could you please confirm what response did you get when you perform below steps:

Xdsdfu.exe -b boot_loader.bin –r

Xdsdfu.exe -f firmware.bin –r

Did you get any error?  If there are error here you may need to replace TM4C1294NCPDT chip.

Without getting success on the above step you will not be able to install new boot loader and hence you will not be able to get COM port as well. Hence it's important confirm on the above steps. 

Thanks and regards,

CHETHAN KUMAR Y.B.

Hi Chetan,

I didn't succeed above step. So  I didn't get COM ports

Thank you,

Pranavkumar Venu,

      It appears that TM4C1294NCPDT or power management chip that powers the chip has gone bad. Unfortunately you may have to replace the chip or order new board. 

Thanks and regards,

Hi Chethan,

I am not good at hardware to replace chips. If I did that, the condition will be even worse. Is there any place in India to get hardware support for that?

I have no intention to buy a new board because I failed a lot. I spend 300 dollars to buy an EVM board then I tried 1000 times to flash the code using mmwave sdk 2 and uniflash but code didn't burn. Then I asked e2e and I understood that my evm is an ES1 device. Why there are two ES versions with the same part number? This makes the problem. I didn't find a sticker or sign on the board that specifies my board is ES1. Finally, I downloaded compact software (mm wave sdk 1) for my evm. Unfortunately, I lost the COM ports and lost the device.

Pranavkumar Venu,

     You may have to work with local assembly house to replace the chips.  Or you may have to order new boards. 

Thanks and regards,
