Current architecture:
TS-7500 mounted on the TS-752 development kit,
Talk to the TS-7500 through the TS-752 Console port using a hypertrm session
running from a Windows XP pro PC.
And its been 9 years since I programmed in a unix environment too :-/ (and at
that not programming at the hardware level)
so please be kind.
The skinny is,
I want to make a simple loopback test, send out, say 5 characters, on one port,
and every time the second port receives the 5 characters it sends back a
message "got 5 chars". If the receiving process gets the first char, but
within say 3 seconds doesn't get the 5th, it sends the string "got less than 5
chars".
Here's what I've got so far:
I wrote a bunch of Uart handlers software for a Rabbit Processor and they all
work fine, but my boss wants it to run on the busybox linux processor on the
TS-7500 board. So I got me a TS-7500 that has the busybox linux on the flash
memory for fast boot, and the full debian linux on the removable card for a
development suite. I got my hello world program working just fine (writing to
stdio), and it even runs fine on the busybox linux (you must compile with the
--static option!!!)
I've got my TS-7500 mounted on the development kit TS-752 that has broken out
all sorts of the pins as described here:
http://www.embeddedarm.com/about/resource.php?item=414 (section "3.1")
meantime along with confusion about the pinouts (looks like there are typos
describing pins 28 and 29 for example)
I'm lost on how to begin. Can anybody point me in the right direction to
programming the UART's in this TS-7xxx environment? Even if its for one of the
other boards, I'm sure it should be not too difficult to convert it.
