LP-EM-CC2340R5: SDK Zephyr release

Part Number: LP-EM-CC2340R5
Other Parts Discussed in Thread: CC2340R5, UNIFLASH

Tool/software:

Hi CC2340 champs,

Looking at ti.com, I see that the SIMPLELINK-LOWPOWER-ZEPHYR-SDK shown on ti.com (https://www.ti.com/tool/download/SIMPLELINK-LOWPOWER-ZEPHYR-SDK) points to GitHub v3.7.0-ti-8.20.04_ea release when GitHub - TexasInstruments/simplelink-zephyr points to v3.7.0-ti-8.40.00 release (more recent)

In order to get TI support to run BLE/Zephyr on LP-EM-CC2340R5, what release should be used ? What readme/guidelines should be followed to ease the process of running BLE/Zephyr here?

Thank you!

Best regards,

Guillaume

    Hi !

    The v3.7.0-8.40 version from github version is prefered, especially if using the CC2340R53 since the release notes change it's quality level from Beta - only tested on samples/bluetooth/mesh to Beta.

    To start using Zephyr for the CC2340R5, we recommend following the instructions from the README from the Github repository. Be aware though that by using those installation steps, building other boards than the CC2340R5 or CC2340R53 might not be supported, and you might need two Zephyr installations in two different folders if that's your case.

    Once you have built a firmware with the TI Github Zephyr downstream, you can flash your board using the newly created .hex file using Uniflash and power cycling your board after flashing.

    Kind regards,
    Maxence
