Hello,
Is is possible to directly access the flash
memory from a user space application, by
using writel and readl functions, or their
userspace equivalents? (writel and readl don't
appear to be available outside of kernel space).
Would mmap be a solution, or does that do caching
on the data reads and writes?
My problem is that I need to do some real-time
logging into a circular buffer in flash. This will
require non-blocking erases, which are not possible
with any of the MTD drivers.
Load-leveling will not be a problem here.
Thanks,
Derek Ross.
