CCS/CC2640: Trying to manually program CC2640. CCS uploads code fine but Flash Programmer 2 doesn't detect CC2640.

Hello,

This is my first post in this forum. I am new to this field and not a expert in this area.

I'm trying to manually program CC2640 without PCB board. I manually soldered the pins and successfully connected the wires to JTAG pins.

When I run CCS and load my program, it uploads successfully. However, the device doesn't pop up on Flash Programmer 2. (Sometimes it does, and sometimes it doesn't).

When Flash Programmer 2 picks up CC2640 chip and when I click right button on mouse and press connect, it fails.

What I'm curious is... using CCS it seems to upload the program without any errors. But I am not sure if that means my program is successfully uploaded.

Based on my description, does it seem like the program is uploaded? I am asking because Flash Programmer 2 doesn't seem to detect CC2640 reliably...

Are you running any of our out of box example? If not, can you try to run driver example that controls some IO and run it using CCS in debug mode.
Make sure you can step through the code.

Then another thing you can do is that running simple_peripheral project and download SimpleLink Starter App to see if you can see your device advertising.

In debug mode, I can step through the code. So I believe the program is getting uploaded correctly. :)
I will need to hook up bluetooth to make sure I get advertisement from the chip.
Thank you!
