GNU Boot also builds some debug images that are shipped in separate
|
|
debug archives (like gnuboot-0.1-rc3_x200_8mb_debug.tar.xz).
|
|
|
|
The debug images have the following differences with the regular
|
|
images:
|
|
|
|
- The serial port is enabled, its speed is set to 115200, and the
|
|
Coreboot debug level is set to 7. It's possible to bring it up to 8
|
|
without recompiling the image by modifying the cmos.default file
|
|
inside the image. In addition POST codes are also printed on the
|
|
serial port.
|
|
|
|
- When the computer has a Coreboot build setting for that (all
|
|
computers but QEMU have that), memory debugging is enabled. This can
|
|
help diagnose RAM compatibility issues to potentially fix them in
|
|
Coreboot.
