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
