* VFS: support .boot.ini and "current" and "previous" os types * fixes for first batch of comments - moved crc32 functions to a seperate file - changed naming of constant with _ - removed one magic number - crc methods now cross platform * using smart pointer for buffer management * created a simple USER_FILE macro for database names * removed commented-out code * style fixes * Updated crc32 version * Update module-vfs/vfs-utils.cpp Co-Authored-By: Alek Rudnik <54846206+alekrudnik@users.noreply.github.com> * Update module-vfs/vfs-utils.cpp Co-Authored-By: Alek Rudnik <54846206+alekrudnik@users.noreply.github.com> * renamed USER_FILE to USER_PATH macro, this was also bromen and was returning incorrect paths, std::filesystem::path behavior is causing these issues. * VFS: remove method changed * fixed path for assets copy * UNITTEST: vfs test fixed * VFS: changed computeCRC32 return type to void * Max supported partition to 2 (was 1) * EOL in vfs.cpp * nullptr check in computeCRC32 include for log.hpp fixed * flash_eMMC merged properly * CRC32 commit update * testBuild * fix newline at start of smsdb.cpp removed test from cmake * no user/ folder on the root of emmc causes sqlite3 to fault this adds a create empty user call for rt1051 * flash script fixes - do not use build-*/sys - common.sh contains a static list of iles that land on the flash Co-authored-by: Alek Rudnik <54846206+alekrudnik@users.noreply.github.com>
