Has each dcache line been invalidated before attempting to enable? I've had
similar problems on ppc4xx processors where either didn't invalidate the
entries, or went to a SOC with different dcache size and ran into problems
like this.

Subject: Question about the dcache of ppcboot??
Hello.
Greetings from korea.
My name is jaechol, and I'm a newbie.
Please excuse my English.
I ported ppcboot-1.1.4 to my custom board with mpc862 cpu.
Everything is OK, except of dcache.
Icache works fine. but dcache don't work
Atfer issuing dcache on, my custom board hangs.
Is there a need that I do for dcache on??
my board:
cpu mpc862
2MByte Boot-flash on CS0
SDRAM on CS2
