SD mount fail on M5Stack basic
-
Hi all, I have problems with lovyan launcher... now the app doesn,t open the sd of the stack basic..
when I burn lovyan launcher with M5burner in a M5stack basic, the sd fail... same proces on a M5Stack gray, works...
on a basic unit, with this sketch, sd fail!!

.... on basic unit with this sketch, sd works

maybe I have to change some pins assignement some where??
tnks a lot!!

the first sketch works, with M5Stack basic, if I modify the M5Stack.cpp library from:
// TF Card if (SDEnable == true) { SD.begin(TFCARD_CS_PIN, SPI, 40000000); }
to
// TF Card if (SDEnable == true) { SD.begin(TFCARD_CS_PIN, SPI, 10000000); }
