Tim, Grant,
just an info.
Very often the Bestcomm-FEC crashed without any error logs if I initiate a
transaction over FEC and save the file to disk (I rememeber I have read
something like that). A restart of FEC don't work.
But no I figured out, if I connect to the other ethernet port of our

Maybe usefull for someone
Adds rs485 support for MPC52xx_psc_uart
To change mode:
echo 1 >/sys/dev/f.soc5200.f0002x000.serial/uartmode
COM1 is console and not selectable.
We choose this way to handle the uart mode by S3 CoDeSys.
I am quite sure this is not the best solution but in our

Tim, Grant,
I have tested the patch on our MPC5200B based board with Kingston Elite Pro
CF-card and it worked fine with DMA2. I have port the patch back to 2.6.24.7
Kernel and I can't detect problems our errors, even with big files (40 mB) over
FEC wich I save to card . We get performance up to
Hi at all,
i have strange problems with my cf_card driver on our MPC5200b board. Because
of our board schematic the cf card is mapped to memory space.
The interrupt is routed to IRQ1. IRQ1 is rising edge sensitive.
First the driver was written for Kernel 2.6.14 with device_driver structure and
