Yay! 🥳

I just made my #TTGO #VGA32 use the #esp32forth variant with #fabgl enabled (a.k.a. #ESP32forthStation ) *and* properly recognize the onboard #sdcard !!

In the end the modification was quite simple, I had to tell the TTGO VGA32 the proper SPI pin configuration for the sd card via SPI.begin() and added that code to the SD.begin word definition.

By default, SD.begin would use the #esp32 default SPI pin configuration which is not being used on the TTGO VGA32 (see TTGO VGA32 pinout).

EDIT: but it took me hours to realize that I used a video resolution which consumed too much memory, causing each attempt to do a "SD.begin" in ESP32forth to fail ... lowering the resolution to 640x200@60 did do the trick! 😎

Time to go to bed ... 🥱

Small RamLoad-fix Update for #RunCPM v6.7
on the #TTGO #VGA32 for using other CCPs
as the Internal v3.1
And not using GPIO32 anymore as HDD-LED, because its a Pin from the PS/2-Keyboard
