Joel Sherrill commented: https://gitlab.rtems.org/rtems/programs/gsoc/-/issues/15#note_122596 @gedare linked to one of the macros involved above. None of them include BLOCK_SIZE which explains why your search failed. Here's a bit of a roadmap to the code. - [IMFS_MEMFILE_DEFAULT_BYTES_PER_BLOCK](https://docs.rtems.org/doxygen/main/group__IMFS.html#gae516a81a3c6a2b16c5063c2885be9dc5) is the default value - [CONFIGURE_IMFS_MEMFILE_BYTES_PER_BLOCK](https://docs.rtems.org/docs/main/c-user/config/filesystem.html#configure-imfs-memfile-bytes-per-block) These are used to set the variable `imfs_memfile_bytes_per_block` with this code [confdefs code](https://gitlab.rtems.org/rtems/rtos/rtems/-/blob/main/cpukit/include/rtems/confdefs/libio.h?ref_type=heads#L178) I see two tests which exercise CONFIGURE_IMFS_MEMFILE_BYTES_PER_BLOCK ``` $ grep -r CONFIGURE_IMFS_MEMFILE_BYTES_PER_BLOCK psxtests/psximfs01/init.c:#define CONFIGURE_IMFS_MEMFILE_BYTES_PER_BLOCK 16 psxtests/psximfs02/init.c:#define CONFIGURE_IMFS_MEMFILE_BYTES_PER_BLOCK MEMFILE_BYTES_PER_BLOCK ``` -- View it on GitLab: https://gitlab.rtems.org/rtems/programs/gsoc/-/issues/15#note_122596 You're receiving this email because of your account on gitlab.rtems.org.
