How can i use test_sd.c to check my sd card?
https://github.com/espressif/esp-idf/bl ... /test_sd.c

When i try to compile the program, i get the message

C:/msys32/home/esp/esp-idf/components/sdmmc/test/build/esp32\libesp32.a(cpu_start.o):(.literal.main_task+0xc): undefined reference to `app_main'

I can't see a app_main in this script?

Sorry for being dull. But i'm at step 'Building unit test app'.
I'm in the directory "test".

make menuconfig - configure unit test app.
>> there is nothing in make menuconfig to configure (also there is no Kconfig.projbuild, so its ok i think)

make TESTS_ALL=1 - build unit test app with tests for each component having tests in the test subdirectory.

I tried 'make flash TESTS_ALL=1'

$ make flash TESTS_ALL=1

And well, yes, i've got no unity.h file

That should work:

Code: Select all

cd $IDF_PATH/tools/unit-test-app/
make defconfig
make flash monitor TEST_COMPONENTS=sdmmc ESPPORT=/dev/ttyUSB0

(replace /dev/ttyUSB0 with your port name)

Problem at step

Code: Select all

make flash monitor TEST_COMPONENTS=sdmmc ESPPORT=com3

Already tried 'make clean' before.

Pullup on GPIO12 setting VDD_SDIO voltage to 1.8V, while flash chip is 3.3V part? Please read readme document in example/storage/sd_card.

Posted: **Wed Aug 16, 2017 9:34 am**

I only want to test the 1-line mode, not the 4-line mode, so GPIO12 is not used.

Are you able to program any other examples successfully using 'make flash monitor'? The output you see indicates that either flash programming or reading data from flash was not successful. Is it possible that you have something connected to the pins used for SPI flash (SD_xx pins)?

Yes, i use some of those pins. But i never had problems by flashing other programs with this circuit.

IO23 and IO19. Is IO14 also with SDCLK one of those pins? I use this also this one.
I disconnected all cables on my ESP32 board, but it's still the same issue. Never saw this message while flashing other programs.
