I bought recently a esp32 wrover chip. Now i want to flash this without a breakout board. Can i also use this wiring for flashing:

Also, do i need specific driver for windows 7 to do so? Or can is just wire everything up and flash it with esp idf / arduino ide?

I want to use the sd card example in Arduino IDE. It's working fine in ESP-IDF. Is this possible?
I included all the librarys, but i get the following error

C:\Documents\Arduino\project\project.ino:17:31: fatal error: driver/sdspi_host.h: No such file or directory

compilation terminated.

exit ...

How can i query the buttonstate of the boot button? I want to use the boot button to call a function. Like

Code: Select all

buttonState = digitalRead(boot_button);
  if (buttonState == HIGH) {
    //do something
  }

I know, that i need pull up resistors in place for sd card using. But can someone explain 'exactly' why?

What is the difference between make build and make all?

Compiling your project

make all

… will compile app, bootloader and generate a partition table based on the config.

But is make build not also doing the same?

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

Type: SDHC/SDXC
Speed: default speed

TEST_CASE("can write and read back blocks", "[sd][ignore]")
{
sdmmc_host_t config = SDMMC_HOST_DEFAULT();

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

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 ...

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
make flash monitor TEST_COMPONENTS=sdmmc ESPPORT=/dev/ttyUSB0
Now i get "Here's the test menu, pick your combo ...
