- After modifying the sensor register settings to suit MT9V034, did you build the firmware and generate a new IMG file?
- Try using a different host application for UVC such as e-Cam View/AMCap and let me know the results.
- In case you have the UART block in your design, please check the UART debug prints to understand the firmware execution.
Yes after i modified the sensor register setting which suit to MT9V034, i had built the firmware and generated a new IMG file in debugger configuration folder. Then i load the IMG file in the debug folder into FX-3 by using choosing I2C EEPROM in the control center. But still no output image.
- If you have got access to the UART block of FX3, please capture the UART debug logs and share the same.
- Capture the USB traces using a hardware logic analyzer (Eg. Teledyne LeCroy) or a software analyzer (Eg. Wireshark) and share the traces.
- Try using a different host application and let me know the behavior.
- I'm referring AN75779 application note, which using I2C to set the image sensor register instead of UART.
Thanks & Regards,
- I2C is used to set the image sensor registers. UART block can be used to capture the debug logs onto a serial port on the host PC. Kindly, capture and share the same.
- Please capture the USB traces during the failure and share the same.
I would like to double check for the MT9v034 have 10bit parallel data bus. As i referred to AN75779, the sensor used only have 8 bit
Currently I'm using the interconnect board to interface the Aptina Mt9v034 and FX-3 eva board.
Do I need to rewire the whole circuit?
MT9v034 sensor streams RAW10 data.
You need to do the following:
1. Configure GPIF for 16-bit bus width by selecting 16 Bit in the Data bus width field of Interface Definition tab of GPIF II Designer.
2. Update the Counter limit value for LD_DATA_COUNT and LD_ADDR_COUNT to 8183, since the GPIF bus width is changed to 16 bits.
3. Rebuild the GPIF project after making the above mentioned changes.
4. Leave the Most significant 6 bits i.e. D[15:10] floating and connect the Least significant 10 bits i.e. D[9:0] to sensor output. These pins are marked as DQ0:DQ9 on the explorer kit
5. Change the Sensor.c file as per MT9v034 requirement
6. Replace the GPIF project and cyfxgpif2config.h with newly built files in step 3
8. Build the firmware in Eclipse and program the FX3.
Collecting the UART Logs:
The Explorer kit has integrated debugger. Please make use of it.
Please refer section 3.7 and page 33 of the SuperSpeed Explorer User guide provided with the kit: C:\Program Files (x86)\Cypress\SuperSpeed Explorer Kit\1.0\Documentation
The Raw10 monochrome will output as YUV format. May I know how does the Raw10 monochrome data split into YUV format, as my understanding Y=8bit, U=8bit and V=8bit. Total = 24bit. The Raw10 data is 10 bit, Y can only store 8 bit the remaining 2 bit will go into U or V?
The SuperSpeed explorer User guide doesn't exist in the C:/, please advise.
