Hi,
I was wondering whether anyone out there would be able to provide me with some information about memory mapping in uCLinux. I have done a fair bit of searching for information and so far i understand that there is some support for mmap() in the uCLinux kernel however i have so far been unable to get it to work.
I have an application which was written using mmap() to map a large data file (120MB) into virtual memory. The application was initially written with desktop/server linux in mind and therefore the assumption that there would be MMU support on the platform.
I am currently trying to port this application to an embedded platform which currently runs uCLinux. The hardware in question is the KB9202B from KwikByte and consists of an Arm core with 64MB SDRAM. It also has a SD/MMC card reader which is where i would like to store the data file. The application only needs read access to the data.
I have read
Regards,
Nick Vaughan.
