Can't write or read the eMMC (IDFGH-1398)

[khorinaj]

I am currently using the ESP32 to read/write sectors for the eMMC devices. The circuit set up is as below.

However, I can get the information from the chip, but the read/write operations are always fail with the error message E (6505) sdmmc_req: sdmmc_host_wait_for_event returned 0x107
E (6505) sdmmc_cmd: sdmmc_write_sectors_dma: sdmmc_send_cmd returned 0x107

void setup(){
Serial.begin(112500);

sdmmc_host_init();

sdmmc_slot_config_t slot_config = SDMMC_SLOT_CONFIG_DEFAULT();
slot_config.width = 4;

sdmmc_host_init_slot(SDMMC_HOST_SLOT_1, &slot_config);

sdmmc_host_t host = SDMMC_HOST_DEFAULT();
//host.max_freq_khz = SDMMC_FREQ_HIGHSPEED;
//host.max_freq_khz = SDMMC_FREQ_PROBING;

sdmmc_card_t card;
sdmmc_card_init(&host,&card);
Serial.println("\n ready to get information");
sdmmc_card_print_info(stdout, &card);

pinMode(15, INPUT_PULLUP);
pinMode(2, INPUT_PULLUP);
pinMode(4, INPUT_PULLUP);
pinMode(12, INPUT_PULLUP);

sdmmc_write_sectors(&card, data, 1000, 1);
Serial.println("check write");
ESP_ERROR_CHECK( sdmmc_write_sectors(&card, data, 1000, 1) );
sdmmc_read_sectors(&card, buff, 1000, 1);
ESP_ERROR_CHECK( sdmmc_read_sectors(&card, buff, 1000, 1) );

}

void loop() {
// put your main code here, to run repeatedly:

the output is shown below

Can you set log level to verbose in menuconfig, and attach the output you get?

[khorinaj]

My project is Arduino based project, I don't think I can change the contents in menuconfig

Can I simply change like this? but nothing change. The error message is the same

[igrr]

No, indeed the log level needs to be set when compiling with the esp-idf. Since your test code is mostly independent from Arduino functionality, can you switch to IDF for the purpose of debugging this? You can also use Arduino library as IDF component: https://github.com/espressif/arduino-esp32/blob/master/docs/esp-idf_component.md
This will allow log level to be changed, revealing more information about the cause of this issue.

I just need to check one thing first. I found that in this paper https://cdn.hackaday.io/files/269911154782944/esp32_datasheet_en.pdf
It said that the SD/SDIO/MMC host controller is available on ESP32 which supports Multimedia Cards (MMC Version 4.41, eMMC Version 4.5 and Version 4.51). Is there any updated eMMC version that the ESP32 supports? Since I am using the latest version eMMC 5.0 and 5.1 for testing.
