I have hit a problem with the E-con systems camera driver (v4l2_driver.ko) that I cannot seem to resolve. I went through the rebuild process as indicated in the instructions, and compiled a new kernel, modules, and v4l2_driver.ko. When try to startup the module using 'insmod v4l2_driver.ko' though, I get the following output / error: root@overo:/CustomBuilds# insmod v4l2_driver.ko Driver Module info : V4l2 driver module Version info : 3.0 Using Reserved memory for V4l2 driver module >From Start address - 0x87a00000 To End address - 0x87ffffff ov3640_i2c_client_xfer:i2c transfer error:-5 ov3640_read_reg:read reg error: reg=300a, val=0 insmod: error inserting 'v4l2_driver.ko': -1 Operation not permitted I am working on the 2.6.33 linux kernel, but I did find an updated patch file to use as indicated in another thread: http://old.nabble.com/Econ-Camera-driver-problem-td28901585.html#a28901585 Does anybody have any ideas on how to resolve or debug this? I am relatively new to the GumStix platform, so I'm not really sure how to proceed with debugging i2c issues in custom driver modules! :) Unfortunately, the SD card that came with the camera has been corrupted, so I can't easily get back to that to ensure it is not a hardware issue. In case this is helpful, I am using an Overo Fire on a Tobi expansion board. Any help would be appreciated. -- View this message in context: http://old.nabble.com/ECON-Camera-Driver-Problem....-tp29211472p29211472.html Sent from the Gumstix mailing list archive at Nabble.com. |

Hi Randy, Add i2c_bus=3,100 in kernel argument on mmcargs in u-boot prompt. This will slow down the controller from 400Khz to 100Khz.

Ananth, Thank you for replying so quickly. I did as you suggested below, but unfortunately, that did not seem to fix the issue. The output appears to still be exactly the same. I received some update source and am going to try rebuilding the driver using that, but if you have any other suggestions, I can try I would really appreciate it. Thank you.

Hi all, After investigating the problem this issue is found related to flex cable connector connectivity. This can be resolved by using good cable having good connectivity.

Did you manage to fix it? How is the quality of the camera? I'm interested in getting one these camera board. randy d wrote: > > Ananth, > > Thank you for replying so quickly.

Hi Randy, Yes, the problem was identified and fixed. The source of the problem is due to improper connectivity between cable and connector.
