ESP32 Core 1 panic'ed (StoreProhibited). Exception was unhandled when tft.init() is executed. #3332

Open taylorjwnc20 opened 6 months ago

taylorjwnc20 commented 6 months ago

The issue that I am encountering is that a "Guru Meditation Error: Core 1 panic'ed (StoreProhibited). Exception was unhandled." just prior to executing the tft.init() function. This issue appears to be only graphics bases since I can execute this sketch with only Serial.println("..."); calls. I can use the Adafruit_GFX.h with the Adafruit_ST7789.h driver to do a test on a GFX application.

During an update something changed and I am at a loss to determine the root cause. Wiring is correct ( I have checked it many times).

  1. IDE - Arduino version 2.3.2 CLI version 0.35.3
  2. TFT_eSPI - version 2.5.43
  3. Board Version - esp32 version 3.0.0.rc3 (I have regressed it back to ESP version 2.0.16 with no change in functionality, still reboots).
  4. PROCESSOR - ESP32-S3
  5. TFT Driver - ST7789 (TFT_eSPI sourced)
  6. TFT Interface - SPI

Plus further information as appropriate to the problem:

  1. TFT to processor connections used
  2. A zip file containing your setup file (just drag and drop in message window - do not paste in long files!)
  3. A zip file containing a simple and complete example sketch that demonstrates the problem but needs no special hardware sensors or libraries.
  4. Screen shot pictures showing the setup

Having a similar issue on a completely different hardware setup (Waveshare round LCD with integrated ESP32S3). Using platformio, this happened once the platform 6.7.0 was updated for espressif32. For now to workaround I am locking the platform version to 6.6.0 in my platformio.ini using "platform = espressif32@6.6.0"

elgerg commented 6 months ago

Looks like this is a duplicate of: https://github.com/Bodmer/TFT_eSPI/issues/3329 ?

APF-MRoger commented 6 months ago

@elgerg Yup, I would tend to agree...

taylorjwnc commented 6 months ago

Yes, I agree with the assessment.... I did not read far enough.... my oversight!

taylorjwnc20 commented 6 months ago

I have since regressed my versions to TFT_eSPI to 2.5.0 an ESP32 to 2.015 and everything is working well. My projects are working as expected . This is true for my ESP32-S3 and ESP32-C3 designs. My ESP32-S3 code test configuration, shown below, now displays the information very nicely. At this point in time, I am ok with the current versions, but still want to work with the current releases.

ats3788 commented 6 months ago

with this platformIO [env:esp32-s3-devkitc-1] platform = espressif32 @ 6.5.0 board = esp32-s3-devkitc-1

; change microcontroller board_build.mcu = esp32s3

framework = arduino monitor_speed = 115200 monitor_port = COM10 upload_port = COM10 build_flags = -DCORE_DEBUG_LEVEL=5

lib_deps = Wire https://github.com/Bodmer/TFT_eSPI.git bitbank2/PNGdec@^1.0.2

it works now with the ESP32-S3

same problem here. I'm using a Seeduino XIAO ESP32-C3 (but basically the same happens on a XIAO ESP32S3) I am using version 2.5.43 of TFT_eSPI and am on version 3.0.0 for esp32

Here's my sketch:

include

include

TFT_eSPI tft = TFT_eSPI();

void setup() { Serial.begin(115200); Serial.println(" Program: " FILE " \n compiled on: " DATE " at: " TIME );

SPI.begin();

tft.begin(); //tft.setRotation(2); //tft.fillScreen(TFT_BLACK); //tft.setTextColor(TFT_BLACK);
}

void loop() { Serial.println ("loop: "+String(millis())); delay (1000); }

as soon as I uncomment the line tft.begin(); I get:

ChrisZang0815 commented 6 months ago

OK, quick update: I first downgraded my versions to TFT_eSPI to 2.5.0 and ESP32 to 2.015 AFter that it worked on XIAO ESP32S3 but on XIAO ESP32C3 I still have the crash Then I upgraded TFT_eSPI back to 2.5.43 and it still works on the ESP32S3. So that seems to indicate that the problem lies with esp32 and not with TFT_eSPI. However I would think that Bodmer has way more pull with the powers to be that write esp32 than we, so I hope that he can do some "magic" there.

ChrisZang0815 commented 6 months ago

one more update: It also works with esp 2.0.17 (which is the final version of 2.0.x) meaning they broke it between 2.0.17 and 3.0.0

final (?) update: "last known good" version for esp32:

SergePD commented 5 months ago

For me, last working core is: 2.0.14

Jptasznik commented 5 months ago

I have spent days trying to get to this point where init doesn't crash. Based on above comment I may try with 2.0.17 board version to see if it works, but I thought I tested it and failed.

ESP core version 2.0.14 is working for me with TFT_eSPI 2.5.43. ESP core versions 3.0.1, 3.0.0 - Crash, sadly I spent 2 days upgrading my solution to 3.X and then ran into this issue. ESP32 S3 16MB Flash. 8 MB PSRAM

2.0.14 works for me. Thanks

mulcmu commented 5 months ago

After much trial and error, I was able to avoid the panic reboot from tft.init() with addition of #define USE_HSPI_PORT in user setup. This was with a custom board 

//Configuration for tft_espi user_setup.h
// #define ST7789_DRIVER  
// #define TFT_RGB_ORDER TFT_BGR
// #define TFT_WIDTH  240
// #define TFT_HEIGHT 320 
// #define TFT_MOSI            10
// #define TFT_SCLK            11
// #define TFT_CS              12
// #define TFT_DC              13
// #define TFT_RST             9
// #define TFT_INVERSION_ON

// #define USE_HSPI_PORT

I don't know how or why...I'm pretty sure I reverted all the other hacks that were tested in TFT_eSPI_ESP32_S3.h

ChrisZang0815 commented 5 months ago

I just tried with esp32 3.0.2. Result ESP32-S3: works, no longer getting panic ESP32-C3: still the same problem

It works !!!!!!! I removed ESP32 then installed version 2.0.14 and version 2.5.0 TFT eSPI. I added the line :

define USE_HSPI_PORT

For pin numbers :

define TFT_CS 10 (I don't have pin 34 on the ESP32S3 weact)

define TFT_MOSI 35

define TFT_SCLK 36

define TFT_DC 7

define TFT_RST 6

Thank you very much... I couldn't have done it without your help.

It also works for me! The interesting thing is... The same code worked two days ago. After that I upload another firmware to test other codes. But when I switched back to the original code, it doesn't work. I guess the issue has something to do with esp32 spi interface.

Thank you so much!

ChrisZang0815 commented 3 months ago

how does that work when every line is commented out?

mulcmu commented 3 months ago

I copy the board settings from the library headers into the project .ino file in case my configuration gets wiped out in a library update. I copied the consolidated settings from my .ino that happened to be commented out. The difference that avoids the panic is #define USE_HSPI_PORT, the rest of the values should be configured for the screen being used.

zachtos commented 2 months ago

I also had the problem and the #define USE_HSPI_PORT was the root cause. Not sure why suddenly it's required? perhaps a library investigation should happen?

Adding DUSE_HSPI_PORT=1 build flag to my platformio.ini avoids the panic reboot in my ESP32-S3. However, my display (ST7789_DRIVER) doesn't work anymore: it shows garbage: image

Anyway, I need to use the faster SPI port to get the maximum performance out of the display. Guess I'll just keep using platform = espressif32 @ 6.5.0

Hello,

I have the same problem . I put some serial print in the code and I found where the guru panic appears.

I use VScode and Platform IO. The problem don't exist if I use a ESP32 wroom but it appears with ESP32-S3 type

the problem is in the function TFT_eSPI::begin_tft_write(void) at the line SET_BUS_WRITE_MODE;

my SPI pinout

#define SCK               12 
#define MISO            13 
#define MOSI            11
#define TFT_SS          38 
inline void TFT_eSPI::begin_tft_write(void){
  if (locked) {
    locked = false; // Flag to show SPI access now unlocked
#if defined (SPI_HAS_TRANSACTION) && defined (SUPPORT_TRANSACTIONS) && !defined(TFT_PARALLEL_8_BIT) && !defined(RP2040_PIO_INTERFACE)
    Serial.println ( "spi.beginTransaction; start ;");
    spi.beginTransaction(SPISettings(SPI_FREQUENCY, MSBFIRST, TFT_SPI_MODE));
    Serial.println ( "spi.beginTransaction; end ;");
#endif
    CS_L;
    Serial.println ( "CS_L; end ;");
    SET_BUS_WRITE_MODE;  // Some processors (e.g. ESP32) allow recycling the tx buffer when rx is not used
    Serial.println ( "SET_BUS_WRITE_MODE; end ;");
  }
}

Log in serial monitor

tft.init()
writecommand(0x00) start ;
begin_tft_write() start ;
spi.beginTransaction; start ;
spi.beginTransaction; end ;
CS_L; end ;
