library not working with espressif32 esp32-s3 Arduino core > 2.0.14

Device crashes at boot.
Open issue in Arduino repo espressif/arduino-esp32#9618 (comment)

I confirm, esp32-s3 reset under 2.0.16 (when init is called), when installing espressif arduino core 2.0.14 works fine

[jfseaman]

I confirm, under 2.0.14 it works for ESP32-C3, ESP32-S3. I did not test ESP32 but same code.

Under 2.0.15 and 2.0.16. Software reset breaks. Actual code from TFT_eSPI_ESP32.h TFT_eSPI_ESP32_xx.h is:

#define SET_BUS_WRITE_MODE *_spi_user = SPI_USR_MOSI
and
#define SET_BUS_WRITE_MODE *_spi_user = SPI_USR_MOSI | SPI_CK_OUT_EDGE

"Guru Meditation Error: Core 0 panic'ed (Store access fault). Exception was unhandled."

[jfseaman]

The issue persists under 2.0.17.

I use PlatformIO
[env:my-esp32]
platform = espressif32 @ 6.7.0
For further exploration of configuration options for the espressif32 development platform, refer to the documentation.

Supported Frameworks
Arduino - v2.0.16 (based on IDF v4.4.7)
ESP-IDF - v5.1.2
I don't even connect the ILI9341 to the board and it reboots

Rebooting...

i met the problem too.
I use 2.0.17 and esp32s3,and the program will reboot when it run tft.init()

[StuartsProjects]

Same here too;

https://github.com/Bodmer/TFT_eSPI/issues/3346#issuecomment-2143324416

A program to transmer images over LoRa and display on a TFT was working on core 2.0.11, but stopped when I updgraded the core.

By going backwards with the cores I found the last one that worked was 2.0.14. For later core versions the program would crash on start.

ESP32S3, Arduino IDE 1.8.19.

Hi there,

I'm suffering for same issue.

• ESP32S3, Arduino 2.0.17

I found a clue on espressif32 Arduino fimeware.

the system reboots when call TFT_WRITE_BITS and i found out the macro uses the below defines

  #define _spi_cmd       (volatile uint32_t*)(SPI_CMD_REG(SPI_PORT))
  #define _spi_user      (volatile uint32_t*)(SPI_USER_REG(SPI_PORT))
  #define _spi_mosi_dlen (volatile uint32_t*)(SPI_MOSI_DLEN_REG(SPI_PORT))
  #define _spi_w         (volatile uint32_t*)(SPI_W0_REG(SPI_PORT))

the macros such as SPI_CMD_REG uses REG_SPI_BASE and the SPI ports are define as 0/1 (HSPI/VSPI)

#define SPI_CMD_REG(i)          (REG_SPI_BASE(i) + 0x0)

however, in the defintion on REG_SPI_BASE, it always returns Null address (because of (i) >=2 )

#define REG_SPI_BASE(i) (((i) >= 2) ? (DR_REG_SPI2_BASE + (i - 2) * 0x1000) : (0)) // GPSPI2 and GPSPI3

And i fix it as ->

#define REG_SPI_BASE(i) (((i) <= 2) ? (DR_REG_SPI2_BASE + (i - 2) * 0x1000) : (0)) // GPSPI2 and GPSPI3

Then it stops to reboot.

However, the macro was stuck in following lines.

Anyone can figure out why?

---

1. espressif arduino firmware seems to have bugs.
2. I have no idea why the macro stuck on while in the macro.

Thanks.

I also have this issue, device re-starts continuously on tft.init()
Was previously using platform espressif32 6.5.0 and framework 2.0.14 on new pc I now have 6.7.0 and 2.0.16, I reverted to platform = espessif32@6.5.0 and and it's ok with 2.0.16

[Kolodieiev]

Temporary solution.

#define USE_HSPI_PORT

#define TFT_DC 15
#define TFT_CS 7
#define TFT_MOSI 17 // sda
#define TFT_SCLK 18 // dcl
#define TFT_RST -1 // TFT reset pin connect to RST

// Позбутися помилки: піни не визначенні для HSPI_PORT
#define TFT_MISO 8 

[SergePD]

#define USE_HSPI_PORT
Yes, It works for me (esp32S3)

[thelastoutpostworkshop]

#define USE_HSPI_PORT
Works for me also in the device setup header file.
thanks

[PhilG1300]

For my ESP32S3 adding #define USE_HSPI_PORT in the variants/esp32s3/pins_arduino.h file in ESP32 version 3.0.1 works too. Had to make other changes for the backlight control as ledc... functions have changed in version 3.
Thanks for the suggestion as I thought I was stuck on version 2.0.14
