Other Parts Discussed in Thread: UNIFLASH, CC3235SF

Hi expert

1. LAUNCHCC3235MODSF just received and tested based on the Out-of-Box Application, and all WiFi functionalities are working fine.

2. After using Uniflash to update the service pack(Netwrok Process Fireware), the Wi-Fi SSID completely disappeared, and Tear Team no longer receives any messages again.

a. https://software-dl.ti.com/ecs/SIMPLELINK_CC32XX_SDK/4_40_00_07/exports/tools/cc32xx_tools/servicepack-cc3x35/README.html

b. plug in EVB, open UniFlash tool and Start imgage creator

c. import SP form SDK

=> C:\ti\simplelink_cc32xx_sdk_7_10_00_13\tools\cc32xx_tools\servicepack-cc3x35\sp_4.13.0.2_3.7.0.1_3.1.0.26.bin

d. Burn

3. How to fix this issue?

Thank you

Hi,

The procedure looks OK, however, this is just for debug through CCS since I can see that you didn't include the MCU image file so the application would not run.

What are you trying to do exactly? do you have your own application?

Hi Shlomi

1. I only recover defaut setting and use SimpleLink Wi-Fi® Starter Pro - Apps. But I cant find EVB SSID to link http://mysimpleLink.net now.

a. Before, I could operate normally with TI YT(www.youtube.com/watch and have a functional demo. However, after I updated the network process service pack, even the Tera team couldn't generate Wi-Fi chip-related logs now.

b. May I ask where the MCU image file(CC3235MODASF) is located in the SDK folder? Perhaps I can try to reflash it along with the service pack again.

2. Another question to ask.

a. I follow UniFlash ImageCreator Basics (ti.com) to setting device mode in EVB(Device type CC3235SF, Device mode Devleop) .

b. No matter how I switch between the two modes, it always stays in production mode. How can I switch it

Thanks

Barry

Hi,

You need to compile the OOB example (or any other example) and include it in the "MCU img" tab. Otherwise, uou would not see anything on the terminal as there is no application code running.

As for development mode, as soon as you set it into development mode and program the device, it should remain in development. If you connect back after programming, you should see development mode on the Device Status.
