Do you see communication going on when you log in using telnet?
Many thanks for your response, on telenet i just see this during upload and print,:
`<ok T:18.75 /0.00 B:17.62 /0.00 @:0 B@:0#ok#
M117 Receiving... <ok#ok# M117 Received <ok#ok# M300 S500 P50 <ok#ok# M117 Printing... <ok#ok# M300 S500 P50 <ok#ok# G90 <ok#ok# G28 <echo:busy: processing#busy# <echo:busy: processing#busy# `......... it was a simple bed leveling gcode.
I can see via telenet that various functions are running. I can't see whether there is communication with the SD card, M20 only outputs the following code:
Info form the UI WirelessPrinting it shows flash memory SPIFFS
Free heap: 229688 File system: SPIFFS Filename length limit: 11 Uploaded file: /cached.gco Uploaded file size: 1136781
Which GPIOs should I use: the standard SPI GPIOs or those of the TTGO-T1? The SPI standard connection works with an SD test under ArduinoIDE?
I did a little test with your gcode to check the SD connection, this is the result:
The gcode:
M22 ; Release SD card M21 ; Init SD card M928 log.gcode ; Start logging to SD card
The result
But I believe the M20 is trying to connect to the memory card on the Ender board and not to the SD via SPI on the ESP32 board. During the test, however, I did not have a card in the SD slot on the Ender Board. The Ender3 v1 does not have enough memory, so in Merlin2.x the write function to internal SD has been disabled, hence the need for an ESP with SD (SPI)
First of all good work, this is the first firmware that allows a wifi interface to upload and print files.
However, I have a problem with my SD card, it is not recognized. I connected the SD card as follows (SPI standard pins). The 32GB SD card is also formatted under linux vfat.

does anyone have an idea how i can activate the sd card, maybe i should use the GPIO connection like the TTGO-T1? thank you in advance for your support.
