Subject: [U-Boot] CONFIG_BAUDRATE doesn't match
Date: Thu, 29 Aug 2013 09:08:20 -0700 (PDT)	[thread overview]
Message-ID: <1377792500628-162206.post@n7.nabble.com> (raw)

Hello,

I'm working with an AMCC based board and I'm running into an issue when I
set my uart0 baud rate. In the include/configs/amcc-common.h there is the
following code:

#define CONFIG_BAUDRATE      115200
#define CONFIG_SYS_BAUDRATE_TABLE  \
    {300, 600, 1200, 2400, 4800, 9600, 19200, 38400, 57600, 115200, 230400}

but after checking it on the o-scope it's not at 115200 baud. It seems like
there is an offset of 3 because if I set the following bauds I get values on
the o-scope like so:

#define CONFIG_BAUDRATE      9600  // o-scope baud = 57600
#define CONFIG_BAUDRATE      19200  // o-scope baud = 115200
#define CONFIG_BAUDRATE      38400  // o-scope baud = 230400

Could someone point me in the direction of how this may be happening?

Thanks!
