Subject: How to do IO mapped Implimentation ???
Date: Thu, 27 Dec 2007 21:12:04 -0800 (PST) [thread overview]
Message-ID: <14522349.post@talk.nabble.com> (raw)
Hi all...
I am writing a driver in which device port is mapped to CPLD and 8 bit data
bus is directly connected from processor to CPLD. Read write on CPLD memory
mapped (buffer/register) is required to control the device. This is now IO
mapped to processor.
I need to know whether i am right if i impliment like this :-
addr=ioremap(base_addr); // Remap to Mem mapped address
outb(addr) and inb(addr);
Please suggest me if i am wrong or there could be better solution to this .
