ESP32-C3 embedded display not working

How to
1

I recently bought a 240X240 display with an embedded ESP32 C3 board with touch.

On Squareline I did the simple program to display a label, nothing fancy. Exported the template files, changed the arduino root to exported folder, updated the driver to GC9A01 inside exported TFT_eSPI UserSetup.h file.

I see the following logs when the code is uploaded to device from Arduino

load:0x403ce710,len:0x25b0
entry 0x403cc710
ESP-ROM:esp32c3-api1-20210207
Build:Feb 7 2021
rst:0x8 (TG1WDT_SYS_RST),boot:0xc (SPI_FAST_FLASH_BOOT)
Saved PC:0x40380082
SPIWP:0xee

And the display never turns on. I am newbie to Squareline and LVGL, what might I have done wrong. Here are the pins that I used

// For ESP32 Dev board (only tested with GC9A01 display)
// The hardware SPI can be mapped to any pins
#define TFT_MISO 5
#define TFT_MOSI 2
#define TFT_SCLK 15
#define TFT_CS 17  // Chip select control pin
#define TFT_DC 16 // Data Command control pin
#define TFT_RST 4  // Reset pin (could connect to RST pin)
#define TFT_BL   22 // LED back-light

#define TOUCH_CS 21 // Chip select pin (T_CS) of touch screen
#define TFT_WR 22 // Write strobe for modified Raspberry Pi TFT only

Attached the schematic files that the vendor provided.

Your defines complete differ from schematics. What you ask?

Can you point me to some Squareline tutorial/article for this device?
Or maybe point out the correct pins so that I can continue with Squareline development, I don’t have much knowledge at hardware side.

Hello, have you been able to solve the problem?

There’s no specific tutorial/document for this device in SquareLine documentation. The TFT_eSPI board-template is not device-specific, you need to set the pins/etc.
