CC3135: cc3135 flash Embedded Programming（upgrade） example

xie ruihua

Part Number: CC3135
Other Parts Discussed in Thread: UNIFLASH, CC31XXEMUBOOST, CC3120

We hope that the firmware of CC3135 can be saved to local flash via Bluetooth. The MCU then communicates with the CC3135 through UART and uses the protocol mentioned in the SWPA231.pdf (CC313x and CC323x SimpleLink

Wi-Fi® Embedded Programming) to program the firmware into the CC3135's flash.

The key here is that the MCU reads the local CC3135 firmware and uses UART to perform the programming for multiple CC3135's. This feature is like UNIFLASH upgrading CC3135 via CC31XXEMUBOOST. Does TI provide a ready-made example of this feature? It would greatly accelerate our development process.

Hi,

I don't think that exist such example for CC3135/CC3235. But you can check EMBEDDED-PROGRAMMING which used for CC3120, CC3220 and contains Python code. I think that code is not fully compatible CC3135, but good for inspiration.

btw ... Uniflash image creator code is written at Python as well. I hope that I don't need to say more...

btw2 ... why you are not using sl_FsProgram() API? It is much easier way for CC31xx devices.
