SD Card not working with FabGL? about fabgl

[fdivitto]

Hi,
please add details. Which board are you using, which pins are connected to the SD Card?

[Kaef]

I'm using a TTGO-T8 board, sdcard pins are:
CS - IO13
MOSI - IO15
SCK - IO 14
MISO - IO2
sdcard is working if I don't use FabGL. When using FabGL the card can not be mounted.

IO15 is used for VSync

Sorry, missing info.
I use:
#include <fabgl.h>
fabgl::VGAController VGAController;
fabgl::PS2Controller PS2Controller;
fabgl::Terminal Terminal;

and in setup() I call:
VGAController.begin(GPIO_NUM_25, GPIO_NUM_26, GPIO_NUM_27, GPIO_NUM_5, GPIO_NUM_23);

is this the board are you using?

If so, I should have one to test.

[Kaef]

yes, nearly; on my board "T8 V 1.7.1, 20190702" is printed

Do you have tested another esp32 board using FabGL and sdcard?

[fdivitto]

Just the prototypes of my board:

Which pins do you use for sdcard?

[fdivitto]

The fabgl defaults. They are listed here:

Thank you very much, I try using the pins you have used and will report if it works.

[Kaef]

I can confirm that using the fabgl defaults the sdcard is working.
When using my gpio definitions my test program is also working fine. So I think the problem is in my code, sorry.

[Kaef]

Problem solved!
Mounting the sdcard failed because free memory was too low, reducing the FabGl resolutions solves the problem.
