J8 Sensor Header Use with M0173 Micro-Coax Kit on VOXL2
-
Hello, the technical docs here reference being able to use the J8U slot (slot ID 5) "with M0076 or M0135, etc, but needs a kernel change due to a reset mapping change". Can anyone elaborate on this? With SDK 1.5, for each VOXL2 hardware version (M0054-1 or M0054-2), there seems to only be one kernel flash option supporting the M0173 camera breakout board.

Hi @isaac,
We only have two variants of the kernel for VOXL2. The default (original) kernel and one that supports M0173. (mach. var 1.0.0 and 1.0.1 respectively, which you can see in output of
voxl-version).If you are using M0135 camera interposer board, you would have to use the first kernel. However, this kernel is set up for a stereo setup in J8, so J8U is not available for regular cameras. If you are using J6 and J7 for cameras, then using M0135 in J8 to enable J8U, is not really possible, even with a kernel modification (due to some shared reset lines that will affect several cameras, if enabled). I would need to know exactly what cameras are connected where in order to provide more details.
Now, if you use the second kernel in combination with M0173, you can also use other adapters such as M0181, M0172. Enabling a hi-res camera in J8U has been discussed in the following thread, with images and instructions : https://forum.modalai.com/topic/4757/connecting-2-boson-cameras-and-2-mipi-cameras-4-cameras-total . Please note that you can use the smaller boards such as M0181 and M0172 instead of M0173 with the second kernel.
I would strongly suggest going the second route, but if you have an issue with this, let me know. I don't have the full understanding based on your brief question.
