Subject: [U-Boot-Users] Setting SIUMCR FYI
Date: Thu, 12 Dec 2002 10:28:11 -0600 [thread overview]
Message-ID: <3DF8B91B.2080400@vss.fsi.com> (raw)
We are using u-boot for our custom board based on the MPC8260. For this
board the chip select 10 pin is configured as BCTL1. u-boot would hang
after SIUMCR was set in cpu_init_f() in the file cpu/mpc8260/cpu_init.c.
The problem is that out of reset OR0[BCTLD] defaults to 0 ("BCTLx is
asserted upon access to the current memory bank" 10-18). My next access
to FLASH hung the system. I moved the assignment of SIUMCR after the
memory controller ORx/BRx registers are setup, where ORx[BCTLD] is set
they way we need, and u-boot ran fine.
As the title suggests this is a FYI. I hope it is helpful.
