STM32479I-EVAL Camara to USB Aplication

[Martin.Sergio]

Hi,

   I recently bought the STM32479I-Eval board and now I'm testing the sample applications included in STM32Cube_FW_F4_V1.14.0

   The application 'STM32469I_EVAL\Applications\Camera\Camera_To_USBDisk' does not work as expected, the LCD screen shows the messages:

USB Init...

Camera Init...

and then:

Press TAMPER button to take a snapshot

Camera Play     

but only a fully blank image on the LCD. When I press the tamper button to save the image:

Camera stopped...

Picture Prepared...

Saving Picture in File image_x.bmp...

Header BMP written...

BMP data Pixed save ongoing...

the LED1 is on to indicate the end of saving operation and a message is displayed:

File image_x.bmp saved in USB Disk...

but the image that is saved (Attach file) is completely blank.

Should I need to modify the position of some other* jumper or even modify the code of the example to run this application in STM32479I-Eval?

* Note:

JP3 of STM32479I-EVAL board is on position PC0.

USB key into the STM32479I-EVAL board through 'USB micro A-Male to A-Female' cable (connector CN8).

Thanks in advance,

Sergio

Hi,

   Anyone with this evaluation board could try this example to verify that it is not a hardware failure?

Thanks in advance,

Sergio

Hi,

   Reading information about the differences between STM32469I-Eval Board and STM32479I-Eval Board (

schematics, 

BOM...

), I think the difference is only the Micro STM32F469I and

STM32F467I

 and I think they are exactly the same except for the cryptographic module (Diferences between Datasheets and the same User manual), so I would not have to touch anything in the application to work correctly. This is correct?

  Any idea how to run the example application correctly?

Thanks in advance,

Sergio

No one knows why this happens?

Hi

Martin.Sergio

,

There is no difference between both boards: same schematic is used.

As you already noted it, the only difference iswithin the STM32 chip where HW crypto is supported for STM32F479 compared to STM32F4

I'll check again the example from my side and come back to you if I have more insights.

Thank you very much st.mcu,

I attach a video in case you see something wrong

(Jumpers, connections...)

Also I attach a photo with all informtation of the Evaluation Board

Thanks in advance,

Sergio

Hi st mcu ,

I'm testing the Examples included in STM32Cube_FW_F4_V1.0

STM32469I_EVAL\Examples\DCMI

And the result is similar... doesn´t work fine, with this examples the LCD is Black (attach images)

Debbuging the code the execution never pass the while condition

***STM32469I_EVAL\Examples\DCMI\DCMI_CaptureMode***

/*##-3- Camera Continuous capture start in QVGA resolution ############################*/

BSP_CAMERA_ContinuousStart((uint8_t *)CAMERA_FRAME_BUFFER);

/* Wait until effective DMA P2M DCMI capture startup in Camera frame buffer */

while(start_the_camera_capture == 0) {;}

***STM32469I_EVAL\Examples\DCMI\DCMI_SnapshotMode***

/* Start the Camera Snapshot Capture */

BSP_CAMERA_SnapshotStart((uint8_t *)CAMERA_FRAME_BUFFER);

/* Wait until frame buffer is ready */

while(frame_buffer_ready == 0) {;}

Thanks in advance,

Sergio

Hi

Martin.Sergio

‌,

Do you have any way to make a test using another camera module?

Hi

st.mcu

,

I have been looking but I can not find where to buy another Daughterboard (MB1183 Camera Module)

Thanks in advance,

Sergio

Hi

st.mcu

,

Any Progress checking the Example.

Reading the forum I've seen more people with similar problem

like

Cachan.Xav

:

'....It seems that the initialization is OK, I can see 'QQVGA camera stream', but then nothing happens, the stream is only a white screen...'

Thanks in advance,

Sergio
