9054 815&845g bar2

plx9054的板卡
原来在pc机下做的驱动程序，其主板芯片为inter 815E
现在要用在工控机上，其主芯片为 inter845g
开发软件均为driverstudio2.7
在调试中发现memrange2(即bar2)初始化失败：在startdevice()中
调用Memrange 的 Initialize()时，返回的不是NT_success,因此，驱动程序初始化就失败了。

有没有大侠遇到这样的问题？
该如何解决呢？

能给我一点相关资料吗?谢谢

by the way,
my question has been resolved.

now i only use bar0 for accessing the pci configuration space.
And any data transfer is implementated by dma transer.

driverworks has many examples.
to implement a driver is simple,
but you must know the plx9054 chip very clearly
and have a basic understanding of the wdm structure.
and windriver can be used to test your card, it very convenient.

wwqq012,你好，我也在做一个9054的驱动，用driverworks,但现在一头雾水，你说你做过，能否给我发一份源程序呢。先谢过了。sean198148@yahoo.com.cn
