Subject: [U-Boot-Users] [PATCH] sequoia uarts
Date: Fri, 01 Aug 2008 16:19:32 -0400 [thread overview]
Message-ID: <48936FD4.3010802@harris.com> (raw)
I have verified that the Sequoia (440EPx) does not have its UARTs
properly configured. The attached patch corrects this by setting three
bits in SDR0_PFC1 to enable 4-wire mode, and to select cts/rts
functionality for the UARTs. Also, I modified the GPIO settings for
pins 34-37 to conform to the tables in section 31 of the 440EPx users
manual.
Here is a dump of the registers once the patch was made. I've verified
that these match the users manual. Also, my Sequoia board works. :-)
