I am evaluating the real-time performance one can achieve using the BealgeV-Fire. Thus I am interested in getting the latest version of the Linux kernel as possible. I have already managed to use the Ubuntu repository to create an Image with the Microchip’s 6.12 kernel. As well as configuring the kernel to my liking. I see, however, that there is a git_linux_mainline.sh script.
How difficult is it to use the upstream 6.19 kernel instead? What needs to be done?
