Hi :slight_smile: !

I’m using a EP9302 board which is made by Olimex.

I followed the instructions of the ivanovp’s site.

My problem: my application can open /dev/ttyAM1, read and write but it seem to be nothing at the second COM.

Please help me!

I have just try do to do with zImage,… from cirrus’s site. Result is good so hardware still be good. Problem come from kernel.

zImage from cirrus’s site was build from kernel 2.6.8.1 while I currently use 2.6.24.rc8. It is amazing . Newer version can not run.

Edit: I’m sorry! kernel which was downloaded from cirrus’s site is 2.6.20.4.
