Thanks so much for your help so far. I was able to find out this
address from the bootloader and get some output on the early debug
console which was very pleasing. It now gets as far as console_init()
called from init/main.c, which completes but then any printk seems to
stall it and you get no more output.
I am using SMC1 and have this in the DTS file for the linux,stdout-path:
[EMAIL PROTECTED] {
device_type = "serial";
compatible = "fsl,mpc8247-smc-uart",
"fsl,cpm2-smc-uart";
reg = <0x11a80 0x20 0x87fc 2>;
interrupts = <4 8>;
interrupt-parent = <&PIC>;
fsl,cpm-brg = <7>;
fsl,cpm-command = <0x1d000000>;
};
Any ideas what sorts of things I should check next?
Check the BRG frequency (clock-frequency in the brg node), and the baud
rate that the driver is trying to set. As a quick check, you can
disable calls to cpm2_setbrg() to see if that's the problem.
