Subject: MP8xx: not initialized CPM RAM crash
Date: Fri, 03 May 2002 07:51:23 +0200	[thread overview]
Message-ID: <3CD2255B.330FA4E4@ardistech.com> (raw)


Hi,

I found in ./drivers/i2c/i2c-rpx.c in rpx_iic_init the structure member
ii->iic_rpbase != 0. Very likely because ppcboot uses this area as initial
stack. This causes the kernel to get a machine check during i2c init. Should
the CPM RAM not be zero'd somewhere during kernel boot?

Regards,
	Bart
