Hello.
I am trying to use sdmmc_read_sectors() to read data from an eMMC module.
The sd_card example, which uses fread(), works well, but the lower level driver functions do not, I get error #109.
I am using this emmc->sd module and adapter.

Is there any advice or resources anyone can offer as I try to debug?
thank you!

I have those adapters as well. I cannot explain why when you stick them in your PC you can use them just fine. Yet when you stick them in a device as a replacement for a uSD they do not work. For instance if you try using it in another device say a RPI board as the boot uSd card it wont boot from it.

I ordered my rock64 a few days ago but I'm not expecting it to arrive for a few weeks yet as I live in the UK.

I ordered a 32GB eMMC from a UK electronics company but I got sent a chip, not a module that would work with the rock64 so I'm having to return it. They had no pictures of it on their site so I didn't know what it was until it arrived.

I've read on this forum that the rock64 is compatible with odroid emmc modules but which odroid model is the rock64 (most) compatible with? odroid.co.uk sells emmc modules for the odroid C1/C1+, C2 or XU3/XU4. I'm not sure if these modules all have different connectors or if its just different software pre-loaded onto them?

Is there anywhere else is the UK or Europe apart from odroid.co.uk and allo that sells emmc modules? Is there a best brand or model to look for? Has anyone done any benchmarks of different emmc modules with the rock64? Tell me everything I might need to know about emmcs and the rock64 please, the rock64/pine64 page doesn't tell us much about this.

This is a post about esp32 using esp-idf.
Like I said, the vfs seems to mount the eMMC, and fread() and fwrite() work well, my question is about why sdmmc_write_sectors() and sdmmc_read_sectors() does not work. The same code works for an SD card, but when I try with eMMC it fails. The documentation simply says to treat eMMC exactly like an SD card, and I can't locate any other info regarding eMMC in the docs or readme's. Any tips greatly appreciated, I found a thread where it seemed like a great deal of work went into the eMMC compatibility, and if anyone has access to docs or any info, I would be grateful.

So what read/write speeds those modules achieve?
Is it faster than WiFi?
Also that errors could be related to file size which is 4GB max for 32bit filesystem

I will be able to determine the actual speed once I get sdmmc_read_sectors() working.
I am trying to read/write a single sector, sector number 1000, which is 512 bytes.
Is there a flag or other member of one of the structs that needs to be different for eMMC to work? The only difference is when using fread() one first calls esp_vfs_fat_sdmmc_mount(), so I am GUESSING that something in that function call sets up something for eMMC, but I cannot find it.

I now have sdmmc_read_sectors() working with eMMC in 1-line mode, however, in 4-line mode, it quietly returns incorrect values. No errors.
Any ideas what's happening?
thank you!

Hi marchinband,

Could you please give some extra information to help us reproduce the issue? What is the part number of eMMC used? Which of the ESP32 pins is it connected to? Are you using the DDR mode? What is the host configuration? (please post the initialization code). Can you please also enable "debug" log level in menuconfig, and post the debug output for this situation? (sdmmc_read_sectors quietly returns incorrect data). In theory, SD interface transfers are protected by CRC, so if incorrect data is read from the interface, this should be detected by the driver...

Edit: in the earlier post you have indicated that you are getting error 0x109, which is a CRC error. The fact that it occurs in 4 line mode but not in 1 line mode almost always points to an issue with signal levels on GPIOs used for D1-D3 lines. Please double check that pull-up resistors are present on these pins.

I get the same result using 2 different parts :
SAMSUNG KLM8G1WEPD-B031
SAMSUNG KLM8G1GETF-B041

The same code works perfectly with an SD card, so I am confident the connections are all correct, and the lines are short enough, etc. I am also very surprised to see wrong data get past the CRC check.

my code :

Code: Select all

void app_main(void)
{
  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;

  sdmmc_card_t card;
  sdmmc_card_init(&host,&card);

  sdmmc_card_print_info(stdout, &card);

  gpio_set_pull_mode(15, GPIO_PULLUP_ONLY);   // CMD, needed in 4- and 1- line modes
  gpio_set_pull_mode(2, GPIO_PULLUP_ONLY);    // D0, needed in 4- and 1-line modes
  gpio_set_pull_mode(4, GPIO_PULLUP_ONLY);    // D1, needed in 4-line mode only
  gpio_set_pull_mode(12, GPIO_PULLUP_ONLY);   // D2, needed in 4-line mode only
  gpio_set_pull_mode(13, GPIO_PULLUP_ONLY);   // D3, needed in 4- and 1-line modes

  static int8_t data[512] = {9};
  static int8_t buff[512] = {0};

  ESP_ERROR_CHECK( sdmmc_write_sectors(&card, data, 1000, 1) );
  ESP_ERROR_CHECK( sdmmc_read_sectors(&card, buff, 1000, 1) );
  int return1 = buff[0];
  ESP_LOGI(TAG, "read %d", return1);

}
