What is the version of Arduino-esp32?

Can you run the example as is without crashing? For example https://github.com/hideakitai/ESP32DMASPI/blob/main/examples/transfer_big_data_one_by_one/transfer_big_data_one_by_one_master/transfer_big_data_one_by_one_master.ino

[piul200]

My development environment is vscode+platformio (Core 6.1.15 Home 3.4.4). I try to run this example, but it still crashes. I removed "master.begin();" and the program didn't crash, but doing so would cause DMASPI to not work

[hideakitai]

What is the version of the esp32 on Platformio? (Please give me your platformio.ini)

https://docs.platformio.org/en/latest/platforms/espressif32.html

Please try adding monitor_filters = esp32_exception_decoder to the example's platformio.ini to decode the backtrace. After running and crashing again, please give me your log again.

[piul200]

Thanks for your reply, here is my platformio.ini and the log of the program crashing again

[env:4d_systems_esp32s3_gen4_r8n16]
platform = espressif32
board = 4d_systems_esp32s3_gen4_r8n16
framework = arduino
lib_deps = hideakitai/ESP32DMASPI@^0.6.3
monitor_filters = esp32_exception_decoder

[hideakitai]

Thank you! Could you try again with build_flags = -DCORE_DEBUG_LEVEL=4 to your platformio.ini? I need this flag and debug log to determine the cause of the panic.

[piul200]

Okay, here's the new log

[env:4d_systems_esp32s3_gen4_r8n16]
platform = espressif32
board = 4d_systems_esp32s3_gen4_r8n16
framework = arduino
lib_deps = hideakitai/ESP32DMASPI@^0.6.3
monitor_filters = esp32_exception_decoder
build_flags = -DCORE_DEBUG_LEVEL=4

Can you try the following begin() (with arguments) method instead of begin() (empty argment)?

  master.begin(HSPI, SCK, MISO, MOSI, SS);

[piul200]

Thanks for your help, I ran with master.begin(FSPI,12,13,11,10); and the program worked successfully. Now my console is constantly printing the following information at a very fast frequency, is this normal?

[  3199][D][ESP32DMASPIMaster.h:161] spi_master_task(): [ESP32DMASPIMaster] new transaction request received (size = 1)
[  3212][D][ESP32DMASPIMaster.h:187] spi_master_task(): [ESP32DMASPIMaster] transaction complete: 2048 bits (256 bytes) received
[  3223][D][ESP32DMASPIMaster.h:210] spi_master_task(): [ESP32DMASPIMaster] all requested transactions completed

[hideakitai]

OK, thank you for testing.

Yes, because you are sending the data as fast as possible in the loop() (no delay())
