VOXL2 Mini UART/SPI Port
-
I see in the user manual the onboard J10 SPI port can be switched to be utilized as a UART port.
The manual states NOTE: this requires a TrustZone devcfg and kernel update. Contact forum.modalai.com for inquiries.Are there any instuctions on how to switch over to UART mode that can be provided?
Also once set up in UART mode my intention is to connect the system to an external flight controller.Many thanks!

Hi @Jack-Bishop ,
Not yet, my current plan is to build two versions of devcfg and kernel and provide both for a release as I haven't found a way to do this swap run time.... We need to rebuild the kernel with a tiny change, which I'm waiting for the dust to settle before doing but that seems to be soon here. Would you be up to test out some 'dev' builds? -
Hi @modaltb
Thanks for your response - We would 100% be happy to test some dev builds if it provides the functionality we require!
I'm a hardware guy myself, but let me know when the builds are ready and I can let our dev team take a look. -
Hi @Jack-Bishop ,
We're working on something that allows you to access the UART that is mapped to the DSP from the applications processor through a 'bridge'.
We are successfully using this for our ESC tools but it's not abstracted yet into a clean example so I'm waiting on that for further possible guidance here that's more 'mainline'.
This is what I'm referencing for short term, e.g.
