malloc error

[maximkulkin]

You need module with external SPI RAM and you need to enable it in configuration: "Components -> ESP32-specific -> Support for external, SPI-connected RAM"

[GermanSheepDog]

Thank you.
Ok, I changed in configuration: "Component config -> ESP32-specific -> Support for external, SPI-connected RAM" to "*" and I didn't change any other configuration.
I got an error: .iram0.text will not fit in region iram0_0_seg

I used a TTGO T-Kamera ESP32 WROVER & PSRAM Camera with PSRAM: 8MBytes.

I suspect that another parameter needs to be changed.

[maximkulkin]

You need to update eps-idf SDK to a more recent version

[GermanSheepDog]

Thank you for your great help, I can compile and download the software. Now I used SPI Flash Size with 4MB.

At homekit I saw images and this worked fine. If I like to get videos I got an ' Core 1 panic'ed (LoadProhibited). Exception was unhandled' error:

DId you enable SPI RAM in menuconfig?

[GermanSheepDog]

Yes, I think I did it. Here are some lines from sdkconfig:

CONFIG_ESP32_SPIRAM_SUPPORT=y
CONFIG_SPIRAM_BOOT_INIT=y

I'm getting the same error, logs below:

Rebooting...

[maximkulkin]

Make sure you follow configuration instructions in README that I added recently.

[GermanSheepDog]

@maximkulkin: I started new from scratch:

1. I deleted directory 'esp32-homekit-camera'
2. Download the whole software: 'git clone --recursive https://github.com/maximkulkin/esp32-homekit-camera.git'
3. Partition Table = Custom partition table CSV, Custom partition CSV file = partitions.csv
4. Component config: ESP32-specific
   • Support for external, SPI-connected RAM = ok
   • SPI RAM config: Initialize SPI RAM when booting the ESP32 = ok
   • SPI RAM access method = Make RAM allocatable using malloc() as well = ok
5. Camera configuration: OV2640 Support = ok
6. ESP32 HomeKit Camera: STA
7. Camera Pins = custom camera pinout:
   #define CAMERA_PIN_PWDN 26
   #define CAMERA_PIN_RESET -1
   #define CAMERA_PIN_SIOD 13
   #define CAMERA_PIN_SIOC 12
   #define CAMERA_PIN_XCLK 32
   #define CAMERA_PIN_D0 5
   #define CAMERA_PIN_D1 14
   #define CAMERA_PIN_D2 4
   #define CAMERA_PIN_D3 15
   #define CAMERA_PIN_D4 18
   #define CAMERA_PIN_D5 23
   #define CAMERA_PIN_D6 36
   #define CAMERA_PIN_D7 39
   #define CAMERA_PIN_VSYNC 27
   #define CAMERA_PIN_HREF 25
   #define CAMERA_PIN_PCLK 19
   This is a WROVER_Kit from TTgo (exactly: TTGO T-Kamera ESP32 WROVER & PSRAM Kamera Modul ESP32-WROVER-B OV2640 Kamera Modul 0,96 OLED).

Results:
a.) Program started, Wifi worked, homekit pairing worked, image loading every 10 seconds worked very well!
b.) If I touch the picture to get the stream I got the 'Guru Meditation Error: Core 1 panic'ed'

From my point of view, I suspect no problem with type of camera or with the pins. I suspect a problem with heap. Is there any way to get more debugging informations?
Is it possible to get your 'sdkconfig'?

I tested with other SPI RAM access methods, for example with 'Integrate RAM into ESP32 memory map':

>>> HomeKit: [Client 56] Update Characteristics
I (1047965) esp32_camera: Initializing encoder
I (1047965) esp32_camera: Total free memory: 99372

x264 [info]: using cpu capabilities: none!
x264 [error]: malloc of size 4098 failed
Guru Meditation Error: Core  1 panic'ed (StoreProhibited). Exception was unhandled.

At the first error messages I missed

I (1047965) esp32_camera: Initializing encoder
I (1047965) esp32_camera: Total free memory: 99372
I (1047965) esp32_camera: Largest free block: 81032

after the message 'Update Characteristics'!

@lockpicker: What kind of camera did you use?

[AchimPieters]

Streaming does not work (Yet). See #11 and #22

[GermanSheepDog]

@AchimPieters
Thanks a lot for this information.
I saw that Issue #11 is closed and suspects that streaming is now working. I did not found Issue #22.
So, now I'm waiting with Maxim...

[Kirankumar-xenlabs]

@GermanSheepDog I am also getting same problem
