How do I compile a specific version of the Raspberry Pi kernel? For example, the kernel version I want to compile is "6.6.20+rpt-rpi-v8" ;
I'm cross-compiling on Ubuntu 20.04 for Raspberry Pi 5 and Raspberry Pi 4, with the systems being Bookworm and Bullseye.
I'm cross-compiling the Raspberry Pi kernel on Ubuntu 20.04 and following these step:The kernel compiled in this way for the 32-bit system can indeed be used, but when I use the "sudo uname -a" command to view the system kernel, it display "Linux raspberrypi 6.6.30-v8 #1 SMP PREEMPT Fri May 3 22:04:21 CST 2024 aarch64 GNU/Linux".
I want to cross-compile the "6.6.20+rpt-rpi-v8" version of the Raspberry Pi system kernel instead of the "6.6.30-v8" version.
How should I proceed to compile the "6.6.20+rpt-rpi-v8" version of the system kernel correctly?
