Ticket Name: Enable channel 5 on TDA2xx

Query Text:
Other Parts Discussed in Thread: TDA2 Hi, I want to enable 6 channels on TDA2xx. My Vision SDK version is v2.08 and running Linux on A15. Now, channel 1, 2, 3, 4, 6 are enabled. But channel 5 still can not work. I did following steps to enable channel 5: 1. Disable NDK in Rules.make 2. Set VIDEO_SENSOR_NUM_LVDS_CAMERAS as 6 in "vision_sdk\examples\tda2xx\include\video_sensor.h" 3. Set pinmux as following: Signal Name from CAMERA Signal used on TDA2 CAM5_D[2] VIN4B_D0 (U4) CAM5_D[3] VIN4B_D1 (V2) CAM5_D[4] VIN4B_D2 (Y1) CAM5_D[5] VIN4B_D3 (W9) CAM5_D[6] VIN4B_D4 (V9) CAM5_D[7] VIN4B_D5 (U5) CAM5_D[8] VIN4B_D6 (V5) CAM5_D[9] VIN4B_D7 (V4) CAM5_HSYNC VIN4B_HSYNC1 (U7) CAM5_VSYNC VIN4B_VSYNC1 (V6) CAM5_PCLK VIN4B_CLK1(V1) Is there anything I missed to enable the 5th VIP port? Thanks, Kevin

Hi Kevin, Your question has been forwarded to Vision SDK experts. They will comment here directly. thanks Alex

Hi, Any update? Kevin

Hi Kevin, I have sent a reminder, team will comment here directly. thanks, Alex

Hi Kevin you need some kernel patches as well, FYI, I have attached both Kernel side and SDK side patches to enable 6ch capture. Please refer the patches, sometime these may not apply automatically on v2.8 version, if fails tray manually regards, Shiju6ch builld.zip

Hi Shiju, Thanks for your patches. I still have two questions: 1. Should I exclude all EVE cores to enable 6 channels? May I include EVE1 & EVE2 for algorithm links? 2. It seems that my dts files are different from yours. I have no idea how to modify them based on your patch. Would you please check the files for me? ti_components/os_tools/linux/kernel/omap/arch/arm/boot/dts/dra7-evm-infoadas.dts ti_components/os_tools/linux/kernel/omap/arch/arm/boot/dts/dra7-evm-vision.dts 1108.dts.tar.gz Thanks, Kevin

Hi Shiju, Based on your patch, I have to modify line 444 in "dra7-evm-vision.dts". But there are only 128 lines in my "dra7-evm-vision.dts". I never changed dts files after I installed SDK. So that I am getting confused. I also got the same problem when I modify "/dra7-evm-infoadas.dts". If you have any suggestion about it, please tell me. Thanks, Kevin

Kevin seems like some versioning compatibility issue. i will check your file & get back to you regards, Shiju

rel2.10-uboot_kenel-patch-for6ch.zipKevin If possible can you migrate to 2.10 release, I have a patch (for both uboot & kernel) to support 6ch capture. PFA the same. BTW, i havn't tested this, please let me know if you face any issues regards, Shiju

Hi Shiju, Thanks for your new patch. Building v2.10 environment and merging code may take several days for us. I will reach you when I am ready. Thanks, Kevin

Kevin Just check if these paches can be manually apply on 2.8 version? regards, Shiju

Hi Shiju, There are only 583 lines in my "mux_data.h", the same issue. mux_data.tar.gz Kevin

mux_data-with-vin4b.hKevin Try use the attched file, I ahve applied the uboot patch on 2.8 version regards, Shiju

From SDK side, modify /linux/examples/tda2xx/src/common/chains_main.c + gChains_usecaseCfg.numLvdsCh = 6; regards, Shiju

As my first post, I have set pinmux by Starterware SDK. This time, I replace mux_data.h with your attached file. But whether I enable/disable my pinmux setting, channel 5 still does not output any frame. Maybe pinmux is not the main problem. I will try to migrate to v2.10. But if you have any other suggestion about v2.08, please let me know. Thanks again for your help. Kevin

Kevin In TDA2X EVM, 5th camera is muxed with Ethernet, it’s a board level Mux issue. so if you enable Ethernet then 5th Cam will not work. i guess in one of the kernel patch I have disabled the Ethernet. BTW, I haven’t tried @ my end. I will check and let you know Regards, Shiju

Hi Shiju, Because of versioning compatibility issue, I cannot use some of your patches. Our commercial agent suggested me setting NDK_PROC_TO_USE as none in vision_sdk/Rules.make to disable Ethernet. So I did. But now I see following messages when booting EVM: [ 7.154053] cpsw 48484000.ethernet: Detected MACID = a0:f6:fd:b3:4a:2e [ 7.161616] cpsw 48484000.ethernet: cpsw: Detected MACID = a0:f6:fd:b3:4a:2f ...... [ 10.200474] using random self ethernet address [ 10.204939] using random host ethernet address I think I have to disable Ethernet in another way. Do you have any suggestion about this? Kevin

Kevin I just did a quick try, I too seeing the 5th channel issue. debuging. BTW, if you are not very paricular on Linux, then try with Bios only build (disable A15 or run Bios on A15) where you can get 6ch LVDS capture working by just set NDK_PROC_TO_USE=none and in chains_main_bios.c set gChains_usecaseCfg.numLvdsCh = 6; //VIDEO_SENSOR_NUM_LVDS_CAMERAS; for "4CH VIP Capture + Mosaic Display" usecase regards, Shiju

Hi Shiju, We need to run OpenGL on Linux. Wait for your good news. Thanks, Kevin

Kevin I could get all 6ch working with VSDK 2.10, Please apply the patch (6CAM_Patch.zip) attached on top of VSDK 2.10 and build/test again regards, Shiju 6CAM_Patch.zip

Hi Shiju, An error occured when I compile chains_main.c with VSDK 2.10. "fatal error: include/config/system_cfg.h: No such file or directory" And I cannot find any file named system_cfg.h under vision_sdk. BTW, readme.txt mentions about Rules.make. But it is not included in the zip file. Can you help me to solve those problems? Thanks, Kevin

Kevin pick only below change for chain_main.c. gChains_usecaseCfg.numLvdsCh = 6; You only need to apply below patches 1. 0001-dra7xx-mux_data-Add-pinmux-iodelay-for-VIN4B 2. dra7-evm-infoadas 3. dra7-evm-vision 4. chains_main - only change is gChains_usecaseCfg.numLvdsCh = 6; for LVDS capture + mosaic display usecase regards, Shiju regards, Shiju

Hi Shiju, I try the four steps on v2.10. And channel 5th works now. Thanks for your help. Kevin

Hi Kevin Thanks for the confirmation:) regards, Shiju
