Dirty Upgrade Path

Goal

• First shot at a kernel upgrade, as lightweight as possible.

  • During the I2S/DAC bringup massacre (the heart of the project) that will follow, we will repeat this step a number of times.

• Therefore:

  • No debian packaging yet

  • Only upgrading the kernel the hard way. No distro, no packaging, no nothing. Just kernel, modules, and Bootloader config.

  • Maybe one or two scripts to speed it up

Steps

• make oldconfig: Debian kernel config, together with the Yocto kernel tree. Massage, build.

• Build

• Copy into Qemu box

  • Adjust Grub config for dual booting both the stable and Yocto kernels

• Repeat until runs
