An open call to create a file on a fatfs on spi flash fails with "no such file or directory". In contrast, fopen works without a problem.

you use xx ? Or /sdcard/xx ? You can leave out the permission flags

This is still an issue; the fat_mode_conv function handles O_CREAT with O_EXCL or O_TRUNC correctly, but falls back to FA_OPEN_EXISTING (failing when the file doesn't exist) with just O_CREAT.
