no, still don't work!!
yes 5 inches.......

yes!!

in SD.h I changed:

    bool begin(uint8_t ssPin=SS, SPIClass &spi=SPI, uint32_t frequency=4000000, const char * mountpoint="/sd", uint8_t max_files=5, bool format_if_empty=false);

to

    bool begin(uint8_t ssPin=SS, SPIClass &spi=SPI, uint32_t frequency=1000000, const char * mountpoint="/sd", uint8_t max_files=5, bool format_if_empty=false);

and in sd_diskio.cpp:

    if (card->frequency > 25000000) {
        card->frequency = 25000000;
    }

to

    if (card->frequency > 10000000) {
        card->frequency = 10000000;
    }

.... and now seems to work!!

I trierd to modify the sd.begin() function in the used SD.h with the new frequency .... but no joy!!

still searching......

any ideas??

nobody?!?!

all the libraries are up to date....

I could upload the code with M5burner, but I need to modify the clock of the sd card in M5Stack.cpp from 40Mhz to 10Mhz to work with M5stack basic....

some tips?

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);
}

tnks a lot to answer!!!

but I can't find where the M5Stack.cpp file is invoked....

mumble mumble...

hi all
I'm trying to use M5Stack-SD-Updater on M5stack basic (V2.61), but after flashing the M5Stack doesn't see the sd card....
same process on M5Stack gray (v 2.4) works...

same behavior if I use M5Burner to burn lovyan launcher on the two controllers... with the same sd card, M5gray can access to sd and M5basic don't

I tried four different M5Stack basic unit ... same behavior!!

ideas?
tnks a lot!!!

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!!
