Please share a link to your branch based off of PX4 main branch and I can take a look.

Hello, I am using PX4 1.16V with skynode X300/v6x and an auterion adapter board v7, im unable to see normal raw CAN 2.0 via menuconfigs for Skynode v6x, it only shows me CANFD, is there a way to access stm32f103 in v6x to enable normal CAN 2.0? Even if I enable CANFD im getting errors in code in s…

Without looking at code or build output there’s nothing I can do to help

Your code doesn’t compile. It looks like your include paths are incorrect. Here’s my advice: Start by getting regular CAN working. Don’t even try to build your custom module until you can first build the firmware and verify that you see /dev/can0 in the filesystem. Also you need to disable uavcan …

i cant make regular can work on v6x since it has only canfd and no option to enable regular can in menuconfigs, could you help me how to turn regular can on in this? i made regular can work for v5x though,

Look at the can.c file, change it back to stm32_caninitialize
