Can't start game on SD Card

[Sampozzo]

Hello, thank you for your great project i have big fun with it!! My problem is that games can't start from SD card, SPIFFS is ok.

I did a little menu at boot to select the game, it show in console that i can read from SD card, but if i try to start a game the esp32 crashes and reboot.

I used your suggested pins and configuration in hw_config.h:

#define FILESYSTEM_BEGIN SPIClass spi = SPIClass(HSPI); spi.begin(14, 2, 15, 13); SD.begin(13, spi, 8000000, FSROOT); FS filesystem = SD;

Your can see in console that the roms can be listed:

`[D][esp32-hal-psram.c:47] psramInit(): PSRAM enabled [E][esp32-hal-cpu.c:115] removeApbChangeCallback(): not found func=400EC25C arg=3FFBEE08 /fs/1942.nes

Rebooting...`

I'm using an ESP32-WROOVER-B with 8mb spram and 4mb flash. SPIFFS works great even with big roms.

Any idea?

Thank you again.

I forget to mention that i ported your Arduino IDE example to platform.io, but it doesn't work on Arduino iDE too.

Hello, someone can help me on this?

[Sampozzo]

I solved my problem removing the SD part in hw_config.h and in the main file on top::

#define SD_CLK 14
#define SD_MISO 2
#define SD_MOSI 15
#define SD_CS 13
SPIClass spiSD(HSPI);

in setup:

//FILESYSTEM_BEGIN

  SPI.end(); 
  spiSD.begin(SD_CLK, SD_MISO, SD_MOSI, SD_CS);
  if (!SD.begin(SD_CS, spiSD))
  {
    Serial.println("Card Mount Failed");`
}
 else
  {
    Serial.println("Card Mount Successful");
  }
  File root = SD.open("/");

I don't know why this works for me. I hope this helps someone with my same problem.

@Sampozzo Can you please share your project, I added M5Stack_TreeView to choose rom and now I get this after I select ROM:

Hi @linkov i shared a little project based on arduino-nofredo ready for paltform.io. It loads a game from spiffs, but it is simple to use SD too, i will share and example as soon as i can.

You can find it here: https://github.com/ZioTester/NESP32 Sorry but blog post is in italian language.

@Sampozzo hey, figured it out, thanks for your support! :D . You can check the repo here: https://github.com/FvnctionHQ/m5stack-nes
