I am working on intel atom Processor E6 series .And I cant boot other os into it other than what was provided by our sponsorer(i am in a college). We are still working on how to load other os, that's because its not like other system with a bios and boot loader(like grub), efi is hard coded into eeprom and I am trying to modify it .
I also tried it on ubuntu 2.6.32-38 , its the same problem .
I have to add sensors(for a portable medical kit) to the board provided.I want to use GPIO as other way to add sensors ex: through USB is power consuming,I cant build a portable device which is power hungry ...
. Hence I am also constrained to using interrupts and making the processor use efficient. But I can as of now i can ignore using interrupts and stick to traditional ways of polling if it can solve my problem.
Are you suggesting that I can still write code to access these pins provided it's run as a kernel module?Because all that I have read till now wanted me to expose these pins first in userspace and then start to code.I do have root privilege so I can develop the GPIO code as a kernel module.
Can you please suggest a place where I can find relevant stuff(write kernel module for devices). New to embedded develpoment please bear with me if I have written something silly
