Unable to Open MT9V034

[chengyuen93]

Hi, I followed the instruction in README.md and installed libusb and python2.7, but when I try to run the script it keeps telling me that "open device failed". Do you know what could be the issue?

Thanks

You have to add sudo before the commands.

Hi

Yes I put sudo in front of the commands. But it still shows open device failed. Should /dev have any indication that the camera is connected?

[ArduCAM]

You can use lsusb to check if there is any new USB devices detected. It should be 52cb:52cb.

Below is before and after I plugin the shield:

Before: Bus 002 Device 002: ID 8087:0024 Intel Corp. Integrated Rate Matching Hub Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 001 Device 003: ID 04f2:b374 Chicony Electronics Co., Ltd Bus 001 Device 002: ID 8087:0024 Intel Corp. Integrated Rate Matching Hub Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 004 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

After: Bus 002 Device 002: ID 8087:0024 Intel Corp. Integrated Rate Matching Hub Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 001 Device 003: ID 04f2:b374 Chicony Electronics Co., Ltd Bus 001 Device 002: ID 8087:0024 Intel Corp. Integrated Rate Matching Hub Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 004 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub Bus 003 Device 002: ID 04b4:8613 Cypress Semiconductor Corp. CY7C68013 EZ-USB FX2 USB 2.0 Development Kit Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

So it seems like I got this 04b4:8613 Cypress Semiconductor Corp rather than 52cb:52cb for MT9V034.

What could be the issue and is there a way to solve this?

[ArduCAM]

Thanks for your information. It seems that the firmware was lost due to some reason. Would you please let me know your email address, I will send you firmware update guide by email.

Hi

I followed your instruction as you mentioned in your email (and with the camera connected). Resintalled the driver (Cypress FX2LP No EEPROM, which is the only option). But when I upload the .iic file you attached in the email, it says programming failed. Is there a way to solve this problem?

Thank you very much for your help.

[chengyuen93]

just to confirm, I am supposed to short the jumper before power up, and once the camera is power up I have to remove the jumper. Then proceed on to updating the firmware right?

[ArduCAM]

Yes, you are right.

[chengyuen93]

Yes, then is there a possible reason as to why it says programming failed? thanks.

[chengyuen93]

Hi, I tried reinstalling both win7 and win8 (not sure if it has got anything to do with the driver but i was just trying it out anyway) on my win10 laptop, and I tried quite a few times and it still says programming failed.

Do you know what could be the reason that it is failing? thanks.

Hi

Loading .hex to RAM says programming succeeded! However, when I tried to auto-open it using USBDemo.exe, the software still crashes.

and also if I want to run it using a python script in Linux, how can i do it since I have to update the firmware in Windows.

Thanks.

[ArduCAM]

Can you see any new device found after loading the firmware?

[chengyuen93]

Yes, which is Cypress FX2LP No EEPROM Device
