Hi,

Thanks for the suggestion, but I do not have the compact flash inserted. I did some debuging of this and I am finding that the /dev/lcd_display

is not being recognised by the system. I am checking the return value from cyg_io_lookup and it indicates that the lcd_display does not exist. I am wondering if any devices are being defined since I get the same results for the LED's.

The stange thing is, in the <cyg/hal> directory I found a devices.h file that was created from the std_2C35.ptf file when I generated the eCos library.

I also know that my dev kit is fully functional because I can use all devices when I run code under MicroC/OS-II.

I am missing something, but do not know what it is.

Thanks,
