CCS/CC3220SF-LAUNCHXL: I made a demo of the demo board according to the official cc3220sf-launchxl principle, and there was a problem when downloading the program.

Hi Dong Lin,

My first suggestion would be to update to the latest Uniflash v4.2.1: www.ti.com/.../UNIFLASH

1. Are you clicking Program Image (Create & Program) to load the demo code?
2. Are you able to see the COM port in your device manager? You can try reinstalling the drivers.
3. Be sure you are NOT using a USB hub and that you do not have any other programs holding the COM port (CCS debug, terminal emulator, etc.)
4. What Rev LaunchPad do you have?

Best regards,
Sarah

Hi Sarah,

I've also tried to upgrade Uniflash to the latest version, but the same problem still happens.
1.I clicked Connect, which also connects to the device, but when I click Program Image (Create & Program), the device will disconnect and the
Program will not be loaded.
2.All com ports are normal.
3.I hava a CC3220SF-LAUNCHXL.


Best regards
Dong Lin

Hi Dong Lin,

Did you try reinstalling the drivers? Which version of the LaunchPad are you using (Rev A or Rev B)? Are you able to debug using CCS?

What operating system are you using? (Windows 7, Mac, etc.)

Best regards,
Sarah
