A rebuild of the boot image (IFS) is required to change this setting. The startup program in the mkifs build file has arguments for the debug output. Change
startup-bios -s64k
to
startup-bios -s64k -K 8250.3f8^0.57600.1843200.16 -D 8250..57600
This will print the kernel dump on the first serial port with a baud rate of 57600.
How do I test this?
-> Run a program with a printf() in an ISR like in the attached example. This often results in a kernel crash. The kernel dump will be printed to the serial port. You have to connect the serial with another machine to see the output.
