RP2040: Example "msc_sdfat" wont compile

[madias123]

Hello,
(Using the Pico core: https://github.com/earlephilhower/arduino-pico)
I cannot get the (for v2 sdfat adapted) example of "msc_sdfat" working:
https://github.com/adafruit/Adafruit_TinyUSB_Arduino/blob/master/examples/MassStorage/msc_sdfat/msc_sdfat.ino

Line 164: sd.cacheClear();
Quits with:
In file included from C:\Users\matth\AppData\Local\Temp\.arduinoIDE-unsaved202356-5956-1sr0qn4.r76ai\msc_sdfat\msc_sdfat.ino:17: c:\Users\matth\Documents\Arduino\libraries\SdFat\src/SdFat.h:448:2: warning: #warning File not defined because __has_include(FS.h) [-Wcpp] 448 | #warning File not defined because __has_include(FS.h) | ^~~~~~~ C:\Users\matth\AppData\Local\Temp\.arduinoIDE-unsaved202356-5956-1sr0qn4.r76ai\msc_sdfat\msc_sdfat.ino: In function 'void msc_flush_cb()': C:\Users\matth\AppData\Local\Temp\.arduinoIDE-unsaved202356-5956-1sr0qn4.r76ai\msc_sdfat\msc_sdfat.ino:164:6: error: 'SdFat' {aka 'class SdFs'} has no member named 'cacheClear' 164 | sd.cacheClear(); | ^~~~~~~~~~ exit status 1 Compilation error: 'SdFat' {aka 'class SdFs'} has no member named 'cacheClear'

So there is no cacheClear() function available.

Things I tried:
Using the newest sdfat library instead of the build in one
Editing the sdfatconfig.h file, like activating
#define USE_BLOCK_DEVICE_INTERFACE 1

So there must be a stupid thing, I forgotten...

Thank you
regards Matthias

you need to use the Adafruit Fork of SdFat https://github.com/adafruit/SdFat

Ok, thank you, so meanwhile there are - at least - 3 versions for the RP2040 (and ESPxxxx) of the Sdfat by Greiman:

1. Original one
2. build in core (ESP8266SdFat)
3. Adafruit Sdfat Library
