v02.01.08. 2) Fixed static noise on audio output. *********************************************************Date: 06/16/2009Version: v010005_061609- Add all missing cropped modes.- Update main menu with all modes.- All modes are now working.- Audio work but has some static noise.*********************************************************Date: 05/06/2009Version: v010003_050609- Fix active video scroll to the beginning of next line by using Tvp5158 patch v02.00.07.- Add audio to option (off is default).*********************************************************- Introduction- Directory

files are placed at mcvip_tvp5158/lsp_files - DM6467 DVSDK - tested with v1_40_00_11 but any version should be fine, CMEM library from DVSDK is used by the test application - Refer to DVSDK installation guide for detailed LSP/DVSDK install instructionsInstructions,- Open file Rules.make in DVSDK folder - Edit it according to user environement - Specifically modify DVSDK_INSTALL_DIR, MVTOOL_DIR, LINUXKERNEL_INSTALL_DIR, EXEC_DIR- Open file RULES.MK in "mcvip_tvp5158/build" - Edit it according to user environement - Specifically modify TARGET_FS, DVSDK_BASE_DIR - Open command line terminal window and goto folder "mcvip_tvp5158/build"- Type > make -s sysall This will clean and build LSP, DVSDK, MCVIP driver. Do this atleast once.- Later to incrementally build > make -s // to build MCVIP driver, test code > make -s lsp // to build LSP > make -s dvsdk // to build DVSDK- The linux bootable uImage would be at $(TARGET_FS)/uImage- The MCVIP test code and related kernel modules would be at $(TARGET_FS)/opt/mcvip Running Instructions====================Requirements,- DM6467 EVM- TVP5158 EVM- 1080i HDTVHardware Setup,- Refer TVP5158 EVM user guide/schematics for details - Connect the provide cable between TVP5158 EVM and DM6467 EVM. - IMPORTANT: Make sure jumper settings on the TVP5158 are done to enable I2C programming from DM6467. - On the TVP5158 EVM, following jumper settings need to be done for I2C access from DM6467 - W3, LEFT - CLOSE - W4, LEFT - CLOSEFor audio: - Remove resistors : R42, R98, and R99 in TVP5158 EVM- Remove resistors : R13, R17, and R31 in DM6467 EVMInstructions,- Boot uImage generated above and come up to linux command prompt. - Refer to DVSDK installation guide for booting the uImage- Goto folder /opt/mcvip - Load the required MCVIP test modules > ./mcvip_load.sh This will load the required kernel modules and drivers for the TVP5158 demo- Reset the TVP5158 DVB - Run the test application > ./mcvip_test.out- Select displayed option to start the required mode - Now the MCVIP demo will start capturing, demuxing and displaying channels on the display- To exit select option "0".Performance===========- Preliminary performance numbers are given below- DM6467 - ARM = 297Mhz, DDR = 297Mhz - EDMA Param Entries = 24 Mode ARM Total Mhz ISR Mhz Task Mhz (ISR+Task Mhz) ------------------------------------------------------------------------------------- 2Ch D1 (BT656) 17Mhz 8Mhz 9Mhz 4Ch D1 (BT656) 34Mhz 16Mhz 18Mhz 4Ch Half-D1 (BT656) 34Mhz 16Mhz 18Mhz 4ch Half-D1 + D1 (BT656) 51Mhz 24Mhz 27Mhz Tested===========- DM6467 - ARM = 364.5Mhz, DDR = 405Mhz Mode Status Comment -------------------------------------------------------------------------------------00: Start - 2Ch D1 - Port A (BT656 ) Ok01: Start - 2Ch D1 - Port B (BT656 ) Ok02: Start - 4Ch D1 (BT656 ) Ok03: Start - 4Ch Half-D1 (BT656 ) Ok04: Start - 4Ch CIF (BT656 ) Ok05: Start - 4Ch D1 (BT1120) Ok06: Start - 4Ch Half-D1 (BT1120) Ok08: Start - 8Ch CIF (BT656 ) Ok Need Cascade argument C1..C409: Start - 4Ch Half-D1 + D1 (BT656 ) Ok0a: Start - 4Ch CIF + D1 (BT656 ) Ok0b: Start - 8Ch CIF + D1 (BT656 ) Ok Need Cascade argument C1..C410: Start - 2Ch D1 - Port A (BT656 ) CROP Ok11: Start - 2Ch D1 - Port B (BT656 ) CROP Ok12: Start - 4Ch D1 (BT656 ) CROP Ok13: Start - 4Ch Half-D1 (BT656 ) CROP Ok14: Start - 4Ch CIF (BT656 ) CROP Ok15: Start - 4Ch D1 (BT1120) CROP Ok16: Start - 4Ch Half-D1 (BT1120) CROP Ok18: Start - 8Ch CIF (BT656 ) CROP Ok Need Cascade argument C1..C419: Start - 4Ch Half-D1 + D1 (BT656 ) CROP Ok1a: Start - 4Ch CIF + D1 (BT656 ) CROP Ok1b: Start - 8Ch CIF + D1 (BT656 ) CROP Ok Need Cascade argument C1..C4PAL display system work only with D1 modes (1, 2, 3, 5, 6, 9).……
