Bay Trail E38xx ATOM ISP Driver

BPeru — Thu, 23 Oct 2014 12:47:49 GMT

Hi all,

We have Congatec QA3 Intel E3845 SOM with its evaluation kit. Currently we are testing Intel E38xx MIPI CSI-2 Camera (AtomISP) driver. We are using Ubuntu 14.04 with LTSI-3.10 kernel where all patches for isp, io drivers are applied. While inserting the camera driver module, we got some errors regarding the virtual and physical paging. Here I have attached the log for your reference.

Thanks for your help.

Hi Lynnz,

Which intel baytrail(e38xx) reference board/evaluation kit we can use to test the mipi csi (camera) interface. Please suggest on this. Whether the ISP driver is tested with any reference platform?

Re: Bay Trail E38xx ATOM ISP Driver

Natalie_Z_Intel — Wed, 31 Dec 2014 17:40:13 GMT

Hi, Balaji P!

Unfortunately none of our current embedded development kits have this interface due to uncommon usage in the embedded space. Are you using the Congatec board by chance as I believe the drivers for Windows OS & Linux OS is available. If you are using the Linux version the customized BIOS might cause the error as well. You can connect with http://www.congatec.com/us/support.html Congatec for support. Or I could have an Intel representative contact you to discuss the possibility of using on CRB on loan. Please let me know if you would like me to coordinate that for you. Happy New Year!! LynnZ.

Hi Lynnz,

Wish you a happy and prosperous new year .

Thanks for the reply. Yes, we are using congatec board for our mipi camera board evaluation, but the driver doesn't work. We already approached congatec regarding the mipi camera support but they told that it is beyond their scope. So, we would like to get support from the intel. We would like to develop mipi camera board for baytrail platform, so please make an arrangement to get the CRB for us to evaluate our camera board. Thank you very much for your support.

And one more query, is it possible to get the prebuilt BIOS binary for e3845 which you are using, so that i will port that to congatec board and check the isp driver.

Thanks and regards,

Balaji P

Hi Lynz,

Thank you very much for your kind support. We are waiting for the intel representative's response. We would like to launch mipi camera daughter board for e38xx in this Q1 2015. So, please make the board availability as soon as possible.

Thanks again..

Thanks and regards,

Hi Lynz,

Good day to you. So far, no one from Intel was contacting me regarding the intel CRB. We are in hurry and we will ready to launch MIPI camera for Baytrail within this Q1 2015. Please help us to get rid of this issue.

Thanks and regards,
