right. now your forced to Azure rtos, because filex only working with enabled Azure.
and "old" fatfs working fine with exfat (has : enable : exfat in settings).
i tried azure+filex now some hours over the last 4 days, just as i feared: cannot mount old 64GB sdcard, i always use for my first tests. and a new 2GB (fat32) card after some 30..40 starts now also no more mount.
and i never write anything !!! only mount and read directory (first entry..called). so very suspicious .
i dont want use filex anymore.
i want fatfs from Mr. Chan again. this never made such curious problems.
I've used newer versions of FATFS on larger volumes (think 200-400 GB), the 2017 versions ST shipped have integrity issues in stress tests, but these were fixed on more recent versions, however ST never bothered to migrate to these. I used my own builds/ports.
Oo , never had the idea, STM still having 6 year old version as "standard" . perfect, fine.
so i put in actual version of fatfs , together with Azure core . 🙂 seem working good now. mount, readdir ok.
Thx for your info .
