i write an streaming minidriver,i use the philps 7146 chip,in this chip
there are 200H registers.in my driver, i overwrite the Testcap example ,at
the HwInitialize() function i use the base
address(ConfigInfo->AccessRanges[0].RangeStart.LowPart) add offset to
access 7146’s registers,I use the READ_REGISTER_ULONG(baseaddress + offset)
to read it,but when the offest exceed 0x7f,it will report
error=50(PAGE_FAULT_IN_NONPAGED_AREA).when the offset less then or equal to
0x7f it work ok.that is i only access 128 bytes.why i can’t access others.
