CC2640: Device hang up after flash reprogrammed

Part Number: CC2640

Hi Team!

My customer would like to know if you could provide feedback on the problem described below.

The problem can be seen consistent on small number of devices.

 

1.       HW Setup

SmartRF06 board, connect to the CC2640 unit using JTAG cable.

2.       SW

Using SmartRF Flash Programmer 2

 

 

3.       Loading new image:   Erase, load, and verify.

After this done, the device should be reboot and start sending beacon.

 

       The problem is on the failure devices, after this step, the devices reboot then get to some weird state and hang.  Signal SPI_CS# supposed to be high, but now it stuck low.
