Hi DiEitch, ... Seen from the picture, the slave may ignore one of the clocks. This is possible to be caused by the SSN when all the data lines changed from 1-0 or 0-1. This is move possible to happen in 4-bit mode. ... Michael. Hallo Michael. About GND, I tried to add conductors, but no changed an...

Hallo.

In any case, thanks for the reply!
I create issue: https://github.com/espressif/arduino-esp32/issues/2860
This problem be in arduino and in eclipse too.
But when I use eps32-at with SDIO mode - all works fine in 1 bit mode.

With the best regards.

About my fifo rx function: int esp32_sdio_rd_fifo(void) { int ret; u16 sz; ret = esp32_sdio_get_pktlen(&sz); //OK if (ret<0) ud_add(uD_Halt); if (ret<0) return ret; ret = sdio_memcpy_fromio(&sdio0, buf81, FIFO_ADDR-sz, sz); if (ret<0) ud_add(uD_Halt); if (ret<0) return ret; return ret; }

Hallo.
In 1bit mode its work ok!

With the best regards.

Hi.
I tried to change, but nothing has changed. Can there be something else?
Also I tried to change directly in sdkconfig.

Who can tell, after changing sdkconfig, I need to do something else if I work in the Arduino IDE?

I check "Support LWIP socket select() only" because
https://github.com/espressif/esp-idf/bl ... ip/Kconfig.

Hi felixcollins.
Thank for reply.
I had no find this option in LWIP section.


With the best regards.

Hi. When I turn on WiFi esp_err_t wifi_setup() { esp_err_t ret; WiFi.mode(WIFI_STA); WiFi.disconnect(true); WiFi.onEvent(WiFiEvent); //not depend delay(100); return ESP_OK; } sdio_slave is hangs. I also try init with low level: esp_err_t wifi_setup(void) { //s_wifi_event_group = xEventGroupCreate();...

Hi to all. Sdio slave->host really work abnormal. I got standart example and some modified: void loop() { esp_err_t ret; //receive data and send back to host. size_t length_rx; uint8_t *ptr; //set_irq(0); const TickType_t non_blocking = 0; ret = sdio_slave_recv(&handle_rx, &ptr, &length_rx, non_bloc...
