Subject: [U-Boot-Users] Reset issue on mpc85xx
Date: Fri, 14 Sep 2007 14:54:31 -0400 [thread overview]
Message-ID: <20070914185431.GB3708@GNU> (raw)
Hello,
I am working on a custom board having mpc8560 and mpc8540. On
porting the v1.3.0-rc1 u-boot, i get a peculiar issue. The board
does not reset on giving the 'reset' command. This is observed
only on the release candidate version of u-boot. I've also ported
the 1.2.0 release and there it works fine.
I tried debugging the issue by putting some debug statements, in
the board.c file after the init_sequence, and what i observe is
that the msr register is getting cleared. But the 1.2.0 version
shows the correct value, i.e 0x1200 which is programmed in the
start.S. After setting the MSR[DE] bit in the do_reset function
along with the DBCR0 register settings, the board resets correctly.
Am i missing something. Please throw some light on it.
