Re: Can cegcc cross compile network driver

Danny,

  Many Thanks! You are not mis-interpreting my message. Further 
information/quesions are:

  1. ACX100 driver is linked against the Linux kernel, what is the module to be 
linked in cegcc? is it libcoredll.a? ( I am downloading the src of cegcc, it 
needs some time :)

  2. What is the relationship between the WinCE NDIS and libcoredll.a, which 
one is sitting on higher layer? I have read and write sth related to NDIS 
protocol driver, I get to know that NDIS has 3 kinds of layers. The bottom is 
the miniport driver, which is the hardware driver. If ACX100 driver can be 
ported to WinCE, it should be one of the NDIS miniport driver, right?

  3. The good thing on WinCE is that all drivers are DLL files, which can be 
loaded dynammically. 

  4. There are functions like (in ACX100 PCI driver): write_reg32(), 
write_flush(),  are these functions supported in cegcc?

  Cheer!

According to my sources and the library on my system, these calls are both in 
our libcoredll.a so you can access them.

Or am I mis-interpreting your message ?
