Maybe you can run some other example (which runs) on the same hardware and compare bootloader log (up to 'entry' line) to see if there is any difference in SPI flash parameters?

Did you try 'make erase_flash'?

It looks like you may have an otadata partition which selects ota_0

Sorry, i haven't read your post. And yes, that was the right clue.

I tried again

Code: Select all

make flash monitor TEST_COMPONENTS=sdmmc ESPPORT=/dev/ttyUSB0

Now i get "Here's the test menu, pick your combo:". But there is nothing, i can only press enter at this point and i'll get
"0 Tests 0 Failures 0 Ignored
OK
Here's the test menu, pick your combo:"

Ok, tried this on my second computer. Weird, it's working there (esp idf versions are the same):

Code: Select all

Here's the test menu, pick your combo:
(1)     "can probe SD" [sd][ignore]
(2)     "can probe SD (using SPI)" [sdspi][ignore]
(3)     "can write and read back blocks" [sd][ignore]
(4)     "can write and read back blocks (using SPI)" [sdspi][ignore]
(5)     "reads and writes with an unaligned buffer" [sd][ignore]

But now i can't select of one those combos with a number. Basically, i can't enter any number/text

Edit: Ah, well, it seems that mingW doesn't view my inputs. For example, when i just type * and press Enter, the test is running.

:can probe SD:FAIL: Expected 0 Was 259
Test ran in 11ms

can write and read back blocks:FAIL: Expected 0 Was 2
59
Test ran in 14ms

can write and read back blocks (using SPI):FAIL: Expe
cted 0 Was 259
Test ran in 23ms

reads and writes with an unaligned buffer:FAIL: Expec
ted 0 Was 259
Test ran in 16ms

Do i have to consider something in the code? I want to test 1 line mode

By default these tests use 4-line mode. You can edit test_sd.c and change peripheral configuration to 1-line mode.

Its working. But i also added highspeed mode to a test case, but its still always default speed.

Name: SS08G
Type: SDHC/SDXC
Speed: default speed
Size: 30436MB

Code: Select all

TEST_CASE("can write and read back blocks", "[sd][ignore]")
{
    sdmmc_host_t config = SDMMC_HOST_DEFAULT();
    
   config.max_freq_khz = SDMMC_FREQ_HIGHSPEED;
   
    config.flags = SDMMC_HOST_FLAG_1BIT;
    TEST_ESP_OK(sdmmc_host_init());
    sdmmc_slot_config_t slot_config = SDMMC_SLOT_CONFIG_DEFAULT();
    TEST_ESP_OK(sdmmc_host_init_slot(SDMMC_HOST_SLOT_1, &slot_config));
    sdmmc_card_t* card = malloc(sizeof(sdmmc_card_t));
    TEST_ASSERT_NOT_NULL(card);
    TEST_ESP_OK(sdmmc_card_init(&config, card));
    read_write_test(card);
    free(card);
    TEST_ESP_OK(sdmmc_host_deinit());
}

In Github master version, high speed support is not implemented. Actually, we have just merged the change internally, which adds high speed mode support. We have some issues with tests now, but once they are resolved, you should be able to get new code from Github and it will support high speed mode.
