Flash Firmware using TI SmartRF Flash Programmer v2
Download SmartRF Flash Programmer v2
Head over to TI's website and download a copy of SmartRF Flash Programmer v2 (also refered to as: FLASH-PROGRAMMER-2). You'll need to register for an account and request approval for the download but it's a quick and easy process.
Make sure you download FLASH-PROGRAMMER-2, not FLASH-PROGRAMMER, as the latter does not support the CC2652 devices used on the Electrolama sticks.
Install SmartRF Flash Programmer v2 and fire it up.
Put your stick in BSL mode
Please follow the following instructions to put your stick in BSL mode:
- Unplug your stick from the host
- Press the
BSLpushbutton and keep holding while plugging the device back into the host:
- Give it a few seconds for the device to settle and set up and release the BSL button
- Your stick should now be in ROM bootloader mode
Identify and select serial port
We need to identify what serial port to use, right click on the Start menu and go to the "Device Manager". Plug your stick in and look under "Ports (COM & LPT)" for the COM Port it will pick up:
If you don't see your stick under "Ports (COM & LPT)" with a COM Port assigned, you may need to install the drivers for it (see here).
With the COM Port identified in "Device Manager", switch over to SmartRF Flash Programmer v2 and click on "Unknown" displayed under the serial port you've identified:
Select correct device
Next up: We need to tell SmartRF Flash Programmer v2 what target device we have on our stick. For zzh, select "CC2652R" and for zzhp/zzhp-lite, select "CC2652P":
Select firmware file and flash device
With the correct serial port chosen and target device selected, click "Browse" and select the firmware you want to flash (see here for help on choosing firmware).
⚠️ WARNING: It is crucial that you download the correct firmware for your stick as using the wrong firmware will disable the BSL and you will need an external debugger / programmer to flash your stick again. Instructions for that can be found here.
With the correct firmware chosen, make sure that "Erase", "Program" and "Verify" are all chosen under "Actions" and press the blue button to start flashing:
If all goes to plan, after a few seconds you should see a green bar confirming that the flashing operating suceeded:
You can now proceed to configuring your software of choice (see here).
If your stick is not in BSL mode or you have not chosen the correct serial port, you will get the following error message:
Unplug your stick and follow instructions above to try again.
