ESP32S3 TFT ESPI GCGC9A01 nothing on screen

[gfranju]

Hello,

I succeed to connect regular ESP32 with a GCGC9A01 screen.
On the other hand, I'm tearing my hair out with an ESP32S3, whatever the model: I have two of them and they both refuse to display anything (WEACTSTUDIO ESP32_S3B)
I've tried several configurations of the users TFT ESPI file but nothing works: the screen is powered but always remains black.
Everything works with an regular ESP32.

I use Animated GIF 2.1.1

ESP32S3 Dev Module

#define TFT_MISO -1
#define TFT_MOSI 11
#define TFT_SCLK 18
#define TFT_CS 15 // Chip select control pin
#define TFT_DC 9 // Data Command control pin
#define TFT_RST -1 // Reset pin (could connect to RST pin)
#define TFT_BL 9

or

#define TFT_CS 34 // 10 or 34 (FSPI CS0)
#define TFT_MOSI 35 // 11 or 35 (FSPI D)
#define TFT_SCLK 36 // 12 or 36 (FSPI CLK)
#define TFT_MISO 37 // 13 or 37 (FSPI Q)

The screen is on but remains black.
RST button have effect on serial monitor.
On the serial monitor, I have :
