HMI Advance esp32-P4 series product

Access to the SD card reader by the tutorial method is successful but access through the SD_MMC library gives this error:
[ 7][I][esp32-hal-psram.c:104] psramAddToHeap(): PSRAM added to the heap.
E (214) sdmmc_periph: sdmmc_host_init_slot: Invalid GPIO number -1, returned 0x102
E (215) vfs_fat_sdmmc: slot init failed (0x102).
[ 221][E][SD_MMC.cpp:305] begin(): Failed to initialize the card (0x102). Make sure SD card lines have pull-up resistors in place.
Card Mount Failed

Is this a known issues or is my board defective?

  • Update:
    Forced the: CrowPanel Advanced 10.1inch ESP32-P4 HMI AI Display board to work with the SD_MMC library by commenting out the logic for other boards & configuration options, and then hard coding the configuration pin numbers/values for the board. Now its just a matter of uncommenting them one by one & testing if it still works after the uncommenting until it trips up again.

    HI, nickp,
    May I ask: what development platform are you using? Is it IDF or Arduino? Also, are you using the code we provided? Furthermore, please provide any related settings/configurations.
    Thanks!
