uC-Linux OLIMEX board LPC2468

Started by Caustic Soda November 1, 2009
Now for experimentation I have the OLIMEX board
http://www.olimex.com/dev/lpc-e2468.html
. This board is already
loaded with uC-linux. It has an FTDI232 chip for USB interfacing. I have
Fedora x86_64 running on my laptop. I installed the ftdi drivers using
yum install. But Fedora does not detect the LPC chip. The kernel in the
dmesg output is shown detecting the FTDI chip but apparently is not able
to sustain the connection. The lsusb command does not list the chip. If
you have faced a similar problem please help me, enlighten me and share
your experience. If you have not faced one and you know how to solve
this problem, help me all the same. Any help would be appreciated.

Why do you think Fedora (or any other OS) should detect the LPC chip
automatically via serial connection ? Isn't it enough to get a serial
port from FTDI, which is connected to one of the UARTs of the LPC ?

Your board should look like a USB serial device to Fedora. If you run 'dmesg', you should see if it was detected and what device was assigned. I usually see something like /dev/ttyUSB0 but it varies.

dmesg | grep ttyUSB

I use minicom to test my serial interfaces. You can try some of the ISP commands from minicom. See the appropriate chapter in the user manual.
