Simultaneously opened files in FatFS?

[JVKran]

Hi there!

Back again with another question. Now that I've finaly managed to get the Bitmap image to show on the display (ST7735), I noticed the playback of audio from the SD card stops when the image is opened and being written to the display.

In contrary of the ESP-IDF, in which one can easily define the maximum amount of simultaneously opened files, I couldn't find such a setting with the nRF5 SDK. Does anyone have a clue where I could find such a setting?

Oh and by the way, I'm using the nRF5 SDK with the SDK for Mesh and FreeRTOS.

Kind regards,

Jochem

Remember that FatFs is an independent 3rd-party product - so have you checked the FatFs documentation?

Hi Awneil,

Yep, that's true. I checked ffconf.h in external/fatfs/src and made sure _FS_LOCK is set to at least 2. I found some more configuration variables that someone had succes with, but to no avail.

#define _FS_TINY 0
#define _FS_READONLY 0 
#define _FS_MINIMIZE 1 
#define _USE_STRFUNC 2 
#define _USE_FASTSEEK 1 
#define _CODE_PAGE 1 
#define _FS_RPATH 1 
#define _VOLUMES 1
#define _MAX_SS 512
#define _WORD_ACCESS 0 
#define _FS_SHARE 0

No luck. The problem remains the same.

Kind regards,

Jochem
