Introduction
============
This is the README for McVIP TVP5158 driver and test application.
The test application is not yet fully ready so some options may not work.

Directory Structure
===================

mcvip_tvp5158 - root folder
|
+ -- bin - executable, load script's
+ -- build - top level Makefile's, common compile/link options
+ -- drv - driver library for generic DMA APIs, generic I2C APIs, TVP5158 kernel module
+ -- lib - generated libraries
+ -- mcvip - MCVIP driver library
| |
| + -- inc - MCVIP driver interface file that should be used by user
| + -- src - MCVIP driver library source
|
+ -- osa - OS abstraction library
+ -- test - MCVIP demo application and other test utilities

Build Instructions
==================

Requirements,
- Monta vista compile tools for Davinci v4.0.1
- DM6467 LSP
- tested with v01_03_00_082 but any version should be fine
- make sure to replace the following files with the files modified for TVP5158 driver
- drivers/media/video/davinci/vpif.c
- drivers/media/video/davinci/davincihd_capture.c
- ti-davinci/linux-2.6.10_mvl401_LSP_01_30_00_082/sound/oss/dm646x/audio_controller.c
- ti-davinci/linux-2.6.10_mvl401_LSP_01_30_00_082/sound/oss/dm646x/audio_controller.h
- ti-davinci/linux-2.6.10_mvl401_LSP_01_30_00_082/sound/oss/dm646x/davinci-aic32.h
- ti-davinci/linux-2.6.10_mvl401_LSP_01_30_00_082/sound/oss/dm646x/davinci-audio-aic32.c
- ti-davinci/linux-2.6.10_mvl401_LSP_01_30_00_082/arch/arm/mach-davinci/mcasp.c
- ti-davinci/linux-2.6.10_mvl401_LSP_01_30_00_082/include/asm-arm/arch-davinci/mcasp.h
- ti-davinci/linux-2.6.10_mvl401_LSP_01_30_00_082/include/asm/arch-davinci/davinci-audio-config.h
- ti-davinci/linux-2.6.10_mvl401_LSP_01_30_00_082/arch/arm/mach-davinci/video_hdevm.c

- the modified 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 instructions

Instructions,
- 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 HDTV

Hardware 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 - CLOSE

For audio:
- Remove resistors : R42, R98, and R99 in TVP5158 EVM
- Remove resistors : R13, R17, and R31 in DM6467 EVM

Instructions,
- 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".
