BHA260 SDK Nicla Board Configuration

[OrsoEric]

I need to customize the BHA260 firmware. I installed the BHA260 SDK and I'm able to generate new firmware for said chip, convert the .fw into a .h file, and upload the BHA260 firmware to the "Nicla Sense ME" board.

The BHA260 SDK doesn't have a board configuration that maps all the drivers on the "Nicla Sense ME" board, I compiled and tested a firmware that maps just the accelerometer and the gyroscope:

The BHYFirmwareUpdate Repo has a 1.1MB firmware with all the drivers of the "Nicla Sense ME" board. Where can I find the BHA260 SDK project that generates said 1.1MB firmware with the drivers for all the "Nicla Sense ME" sensors?

below the output of the list sensor ID .ino on the two firmware, on the left the SDK firmware, on the right the Nicla FW firmware, listing the virtual driver IDs:

I need the SDK source that generates the firmware on the right, for which I only found the binaries. I only have the source for the firmware on the left.

@manchoz is there any chance we can obtain this piece of information?

[manchoz]

Hi @gmacario, being a binary blob provided by the sensor manufacturer, we need to discuss it with the original author of the firmware.

We will keep you updated.

[gmacario]

We will keep you updated.

Do you have any updates on this subject @manchoz ?

@gmacario
this repo only provides some pre-built FW for the BHI260AP sensor, for customization, maybe you could raise the request on: https://community.bosch-sensortec.com/t5/Bosch-Sensortec-Community/ct-p/bst_community
