About the 10Mp stream of ipnc8127 rdk

We have the same problem. There is no option for 10mp streaming, and release notes for GA_3.0.0 said there should be. Can someone from TI tell us something more about this. When can we expect to get 10mp streaming?

Hi,

In low-power mode,
in GUI select :  Tri-stream ->H264+H264+MJPEG -> 10MP...

Regards.

GA_3.0.0 low power mode:

Single and Dual steam work properly.

Tri-stream only works with 1080p. For higher resolution (5MP, 8MP and 10MP) the displayed image is black. When you are in some of those modes and want to switch to another mode (single or dual stream which works properly at the first time), there is the message "login faled". Only camera reset solves this problem.

In any case, there is no video stream resolutions higher than 1080p. When you choose this higher resolution in the three-stream mode, there is not shown any pictures, ie. the image is black.

Does anyone have the same problem?

Regards,
Jelena

Hi Jelena,

Can you delete old configuration files on camera. In console type :     rm  /mnt/nand/*
Then restart camera.

Regards.

Marko,

I tried that (deleting configuration files), but no help.
Actually, in the meanwhile firmware was broken several times. I managed to solve that by flashing system from the beginning.

But, at the end the camera stopped to work completly, and I got message like this:

Jelena,

UBI errors has something to do with ECC errors when using UBIFS filesystem.
Nand blocks get marked false bad over time, so you will have to fix this with "nand scrub".
I hope TI, or someone will fix this issue in the next IPNC release, since almost everyone has this problem.

Before reflashing, you need to do "nand scrub" from uboot, to fix incorrectly marked nand bad blocks.
You can check bad blocks with "nand bad".
If you don't want to reflash uboot, then do "nand scrub" only on that nand range where kernel and filesysem are flashed.
e.g  "nand scrub  0x280000 0xFD80000".
Note that nand scrub will erase all data on the selected range. If you erase uboot, you will have to reflash it by CCS or SDCard.
-------------------
Anyway if you boot from NFS kernal + filesystem, you won't get UBI errors. And you can try 10MP from NFS.
Or you can try SDCard boot. Look at:  IPNC_RDK_InstallGuide_Version3.0.0.pdf :  1.6.6 Flashing images to NAND Using SD Boot,  3.1.2 Boot from SD
-----------------

Regards.

Jelena,

I might be able to help you out with UBIFS issues. Could you please send me the following files to renjith.thomas@pathpartnertech.com?

arch/arm/mach-omap2/board-ti8127evm.c or the relevant board file for your platform? 
arch/arm/mach-omap2/board-flash.c
arch/arm/mach-omap2/gpmc.c
drivers/mtd/nand/nand_base.c
drivers/mtd/nand/omap2.c

Also send me the steps followed in creating/flashing the ubi image? Send the complete logs as well.

Thank you all for the help and advices.
At the moment we need to do some tests with high resolutions, so we went back at old and more stablie release Ver2.8 low power mode which has support for resolutions up to 8MP.

Later we will come back to GA3.0.0. Maybe in meantime TI come up with some new and more stabile version.

Regards,
Jelena
