hello,
Trying to migrate an old project to latest code. I have this config
after migration.
$ ag LITTLEFS .config
1928:CONFIG_FS_LITTLEFS=y
1929:CONFIG_FS_LITTLEFS_PROGRAM_SIZE_FACTOR=1
1930:CONFIG_FS_LITTLEFS_READ_SIZE_FACTOR=1
1931:CONFIG_FS_LITTLEFS_BLOCK_SIZE_FACTOR=1
1932:CONFIG_FS_LITTLEFS_CACHE_SIZE_FACTOR=4
1933:CONFIG_FS_LITTLEFS_LOOKAHEAD_SIZE=0
1934:CONFIG_FS_LITTLEFS_BLOCK_CYCLE=200
1935:CONFIG_FS_LITTLEFS_NAME_MAX=32
1936:CONFIG_FS_LITTLEFS_FILE_MAX=2147483647
1937:CONFIG_FS_LITTLEFS_ATTR_MAX=1022
I can not mount a blank mtd partition on a sst26, cpu is stm32f429
I see make.defs has version 2.5.1
and cmakelists has version 2.4.0
So much for modern build systems, nuttx is not rigorous enough to
maintain both in sync, as warned by me and others when people wanted cmake.
Here is what happens at runtime with 2.4.0 (fs/littlefs/Make.defs
changed manually and nuttx rebuilt):

That is definitely not a good stack pointer. LFS 2.4 does not work.
.name_max=0, .file_max=0, .attr_max=0 are very suspicious.
Trying again with 2.5.1 I get this:
