1.28inch_ESP32-2424S012 boot loop

[chung1608]

LCD works fine when I use ESP32 library ver2.0.2 but when I update ESP32 library to 3.0.5, ESP32 falls into boot loop

17:40:08.708 -> rst:0x3 (RTC_SW_SYS_RST),boot:0xc (SPI_FAST_FLASH_BOOT) 17:40:08.708 -> Saved PC:0x40048b82 17:40:08.708 -> SPIWP:0xee 17:40:08.708 -> mode:DIO, clock div:1 17:40:08.708 -> load:0x3fcd5820,len:0x458 17:40:08.708 -> load:0x403cc710,len:0x814 17:40:08.753 -> load:0x403ce710,len:0x2880 17:40:08.753 -> entry 0x403cc710

Can you send your setup? Pin defines file

I have the same problem, with version 3.0.1 of esp32 on arduino it works correctly, with the latest version it goes into a reset loop.

I use a 3.5" SPI TFT the user_setup file is configured like this:

define TFT_MISO 19

define TFT_MOSI 23

define TFT_SCLK 18

define TFT_CS 15 // Chip select control pin

define TFT_DC 2 // Data Command control pin

define TFT_RST 4 // Reset pin (could connect to RST pin)

//#define TFT_RST -1 // Set TFT_RST to -1 if display RESET is connected to ESP32 board RST

// For ESP32 Dev board (only tested with GC9A01 display) // The hardware SPI can be mapped to any pins

//#define TFT_MOSI 15 // In some display driver board, it might be written as "SDA" and so on. //#define TFT_SCLK 14 //#define TFT_CS 5 // Chip select control pin //#define TFT_DC 27 // Data Command control pin //#define TFT_RST 33 // Reset pin (could connect to Arduino RESET pin) //#define TFT_BL 22 // LED back-light

define TOUCH_CS 21 // Chip select pin (T_CS) of touch screen

The serial monitor output is:

Can you add this line and test:

#define USE_HSPI_PORT

Can you send your setup? Pin defines file this is HW fix pin I can't change

define TFT_MISO -1

define TFT_MOSI 7

define TFT_SCLK 6

define TFT_CS 10

define TFT_DC 2

define TFT_RST -1 // Reset pin (could connect to Arduino RESET pin)

define TFT_BL 3

I have defined it in user_setup and it is still the same

Sorry. Misread your MCU model. It works on ESP32-S3. Are you sure the reset is because of TFT_eSPI? if you put

while(1);

right after tft.init(); line still reboots?

[chung1608]

reboot right after tft.init();

[Basitadam]

reboot right after tft.init();

Now I see. You have ESP32-C3 board. Can you test with this "TFT_eSPI_ESP32_C3.h" file from this link:

https://www.filemail.com/d/bsgocapqwmdpeyj

I had the same issue. Modified the .h file

another isssue, do not exit init_tft

Strange. Here is my setup, tested again now, works OK:

And output:

SPI pins are different but you said your setup was working before

Works well on ESP32 3.0.7, too
