I would like to ask about the usage of the mmap() function in RTEMS. At present, I am attempting to read from and write to files on RTEMS. However, I have encountered an issue where, upon using the mmap() function, I discover that I lack the necessary read and write permissions.
Writing through an mmap() to the underlying file is not supported. The mmap() support that is there has several limitations. It’s possible the limitations regarding using mmap() on a file are not fully documented. 13. Memory Management Manager — RTEMS POSIX API Guide 7.8923d90 (14th April 2025) documentation
ok！thanks！ I’ll look for other ways to solve this problem.
