Hello,

I haven't had this issues before, but recently, whenever I flash any code involving an SD card, the ESP board I am using (ESP32-S3-WROOM-1) disconnects from my PC.

SD card module used: https://www.amazon.com/pzsmocn-Micro-SD-Compatible-Raspberry-Teaching/dp/B08FB3GC34?source=ps-sl ...

What specific pin is 'D0' connected to?

pin 37 my bad

Hello,

I have succesfully flashed the TUSB MSC example onto my ESP32-S3-WROOM-1 board. It is connected to a 9 pin SD card module with pin 35(CMD), pin 36(CLK), and pin 37(D0). I am in 1-bit SDMMC mode. I am using a Male to DIP USB converter to connect a USB ( https://a.co/d/62fJOIy ) with D ...

For the ESP32-S3 WROOM-2 board, based on the initial logs, it appears that Octal Flash mode is enabled. According to the documentation https://docs.espressif.com/projects/esp-dev-kits/en/latest/esp32s3/esp32-s3-devkitc-1/user_guide_v1.1.html#description-of-components, GPIO35, 36, and 37 are used ...

Hi, My mistake — there's no need to explicitly deinitialize SDMMC, as it's already handled internally by the esp_vfs_fat_sdcard_unmount() function. I tested the example https://github.com/espressif/esp-idf/tree/master/examples/storage/sd_card/sdmmc by mounting and remounting the SD card in a loop ...

Hellooo

I am trying to flash the SDMMC example from the IDF github: https://github.com/espressif/esp-idf/tree/master/examples/storage/sd_card/sdmmc . I have three boards:

1) a ESP32S3-WROOM-1
2) a ESP32S3-WROOM-2
3) a ESP32S3-WROOM-1 N16R8

I am in 1-bit mode with CMD(pin 35), CLK(pin 2), D0(pin ...

Hello, from your question, what I understand is that your setup includes a mechanism to temporarily switch the SD card lines to another device, effectively disconnecting it from the ESP32. If that’s correct, then the behavior you're observing is expected. When the SD card is mounted using esp_vfs ...

Hello everyone,

I've decided to create a webserver that lets you wirelessly upload files to an sd card connected to the ESP board. I need to have a mechanism where the sd card's lines are switched to another device briefly, meaning it won't be connected to the ESP board. I'm testing the code right ...

if ((ret = httpd_req_recv(req, buf, //READ INTO BUF, AKA STORED IN BUF
MIN(remaining, sizeof(buf)))) <= 0) {


sizeof(buf) is the size of the pointer buf, i.e. 4. So per iteration you're reading 4 bytes and vTaskDelay()'ing for 10ms, limiting the throughput to 100*4=400 bytes/second max ...

Hello,
Trying to upload files to microSD card wirelessly through a website. The upload time for a 36 kB image is 1 min 30 seconds. It gets worse for larger files (8 minutes for a 210kB file). It also times out and gives me these errors:

Error 1: wifi:bcn_timeout,ap_probe_send_start
Error 2: httpd ...
