I have a Verdex pro XL6P/robostix/netpro-vx combo. The robostix brings
out the FFUart and STUart. I have no problems using the stuart and
connecting it to external devices. However, when connecting the ffuart
to an external device that begins sending data immediately upon powerup,
it causes uboot to stop autoboot and drop to the prompt.
I am using OE and I have read that uboot will not build under open
embedded. I have also heard that there is a configuration option in
u-boot that will cause it to only leave autoboot if it receives a
certain string when it boots.
My first question is does anyone have any pre-compiled u-boot binaries
with this parameter set so that I can still access u-boot if I need to
but use the serial port in normal operation? Failing that, does anyone
have any suggestions for re-compiling u-boot? I am somewhat worried
about bricking my stack by uploading a faulty image, so a pre-compiled
image would be great.
