Hi all,

 

I follow this step of below link to setting my config.

https://blackfin.uclinux.org/doku.php?id=video_loop_back

 

I don't have ADZS-CAM-EX3 boad, i just connect ADZS-WVGALCD-EX3 to P2A and P3A.

For my buildroot, toolchain and kernel version is 2014-R1 (toolchain version is 4.3).

 

But im not found gpio112, did i miss some procedure?

 

bfin> version

U-Boot 2013.07 (ADI-2014R1) (Jul 09 2014 - 18:58:06)

bfin-uclinux-gcc (ADI-2014R1-RC2) 4.3.5

GNU ld (ADI-2014R1-RC2) 2.21

 

root:/> version

kernel:    Linux release 3.10.10-ADI-2014R1, build #2 Fri May 20 00:12:17 CST 2016

toolchain: /home/jeremysu/workspace/ADI/BF609/source_code/adi-buildroot-code/output/host

user-dist: release git-a2d3abe, build #1 五 5月 20 00:01:40 CST 2016

 

another question, I was load the uImage at every booting.

ex.

tftp 0x1000000 uImage

Could I copy 0x1000000 to any other non-volatile memory?

and set auto-running at there?

 

Thanks and regards,

Jeremy
