Hi Kim,
There are a couple changes required here that will make this work:
1. Rebuilding Kernel with SPI14 enabled
You're going to have to rebuild and flash the kernel with QUP14 enabled as SPI. There is also a directional level shifter on GPIO67 that needs to be set to high in order for SPI on QUP 14 to work. I created this branch for you that should have the kernel changes that you need:
- feature/voxl2-mini-spi-qup14 (link)
In order to actually build and flash the kernel please follow the instructions from our public docs on how to build the kernel
When building the kernel, after syncing but before building, make sure to go to the cloned meta-voxl2-bsp directory and checkout the branch that I created (feature/voxl2-mini-spi-qup14).
Also there is a chance you may need to build a kernel variant depending on your device so also make sure to check this document to see if you have a -2 device which would require building the kernel with the -v var02 flag
2. Configuring Trustzone with Correct QUP
I would recommend using the devcfg binary that comes from the `voxl2-mini_SDK_1.0.0.tar.gz. In order to flash devcfg you'll want to run the following command
fastboot flash devcfg <path/to/voxl2-mini_SDK_1.0.0/devcfg>/devcfg.mbn
You should flash the kernel and devcfg (Trustzone) during the same fastboot session to avoid running into any issues with the device booting.
Let me know if you have any additional questions or run into any issues!
