The SD card module works on ESP32. Great!

Please can you post your wiring and script you used, as @jumjum was trying to get that to work and did not have success.

Hi, do you mean codes using SD card on ESP32? or SPIFFS file system?

@user73896
I mean the javascript you used to get the spi SD card working, and the wiring and pins you used - perhaps even a photo!

Version ESP32-2.01 says:

>SPI2.setup({sck:18, miso:19, mosi:23});
=undefined
Uncaught Error: Unimplemented on Linux
 at line 1 col 24
E.connectSDCard(SPI2, 5);
                       ^

Were there any code updates to allow larger data sets to be saved to flash also?

Thank you.

The esp32 build has a flash file system using 1mb of the 4mb inbuilt flash.

Support for external sd card has not be implemented. It could be supported however the flashfs implementation would need to be disabled.
