#define SPI_FREQUENCY 80000000 

1. M5.Lcd.drawJpg(f1, sizeof(f1));

2. M5GFX display.drawJpg(f1, sizeof(f1), 0, 0);

I'm rendering a const unsigned char f1[] image on the LCD, but the refresh rate is slow. You can see a black area at the bottom when updating drawJpg.

I'm using the M5Stack Core2. Any help would be greatly appreciated!

Thank you!

#include <M5Core2.h>
#include <SD.h>

void setup() {
  M5.begin();         
  if (!SD.begin()) {
    M5.Lcd.println("SD card initialization failed!");
    return;
  }
  M5.Lcd.println("SD card initialized successfully.");
  M5.Lcd.drawJpgFile(SD, "/email.jpg"); 
}

The image is not loading on the lcd.
320x240 rgb jpg format.

anything I miss? please help! Thank you!

Thanks @ajb2k, I can burn the firmware now. Can you tell me where I can get the shipping firmware?

I love to use the keyboard and radio app. Thank you!

I'm using M5Burner on MacOS. After I burned UIFlow2.0 to my Cardputer, I can't burn any other .bin files.

Now, I can only access the develop button on my Cardputer. How can I reset it back to the original shipping firmware? Any help would be greatly appreciated. Thank you!
