Hi,

Please try to use the latest Processor SDK RTOS 5.0 release for this effort. Also, do you use TI AM571/2/4x IDK or AM572x GP EVM or your customized board for this integration?

Have you tried the existing VIP capture or VPS loopback examples to understand the callflow?

There are some training document under: pdk_am57xx_1_0_11\packages\ti\drv\vps\docs\training, at least:
FVID2_init
–Initializes the drivers and the hardware. Should be called before calling any of the FVID2 functions

VPS is a very complicated driver, you may need to step/look through the existing work cases before porting a different camera sensor.

Regards, Eric

Thanks for reply. Following you advice I added FVID2_init before FVID2_create and some problems are solved. But the Fvid2_Handle is still NULL after Fvid2_create functions. I have some questions about VPS： 1. I haven't find any FVID2_init in the example "vps_loopbackExample_idkAM572x_armExampleProject" offered within PDK(pdk_am57xx_1_0_11), are you team sure that it can be run successfully on IDKAM572x? 2. In the html "C:/ti/pdk_am57xx_1_0_11/packages/ti/drv/vps/docs/doxygen/html/group___b_s_p___d_r_v___d_e_v_i_c_e___v_i_d___s_e_n_s_o_r___a_p_i.html", one table below the line "Creating the driver - Fvid2_create()" shows how to use Fvid2_create(), the second parameter "instanceId" is set to 0,but how do the driver know which port does my AR0132 connects to?The fifth parameter "cbParams" is set to NULL, is that means i can't use the frame callback function when the drvId is set to FVID2_VID_SENSOR_APT_AR0132_DRV ? 3.Is there any examples for EVMAM572x?

Hi I created an loopback example for my evmAM572x board and it works. And I wrote my own vin2a initial function with Fvid2_init inside firstly, The problem is that I got fvid2Handle null after Fvid2_create, but fvid2Handle is returned successfully when I put my function after LpbkApp_init(appObj) in the loopback project.(with Fvid2_init is commented cause i know Fvid2_init is already contained in the LpbkApp_init->BspUtils_appDefaultInit). Question 1. Is there any other functions (except from Fvid2_init) that must be added before Fvid2_create? Quextion 2. The function BspUtils_appDefaultInit in 'ti\drv\vps\examples\utility\src\bsputils_app.c' contains VpsInitParams_init and Vps_init.Is these what I need before Fvid2_create? And where are these 2 function declared?

Now i found vps_init and added VpsInitParams_init and vps_init after fvid2_init. But error occurs when run to vps_init: No source available for "do_AngelSWI(int, void *).
My project is copied from rtos teplate a15 and initialization order list as follows:
--------------------------------------------------------------

main()
{
Int32 retVal = BSP_SOK;
Vps_InitParams vpsInitPrms;

Board_initCfg boardCfg;
int status;
System_atexit(appExitFunction);
boardCfg =
#ifndef SBL_BOOT
BOARD_INIT_PINMUX_CONFIG |
//BOARD_INIT_MODULE_CLOCK |
#endif
BOARD_INIT_UART_STDIO;
status = Board_init(boardCfg);
if (status != BOARD_SOK)
{
appPrint("\n Init Board: ERROR.\n");
}
else
{
appPrint("\n Init Board: OK.\n");
}
//unfolding peripheralInit
UART_init();
I2C_init();
GPIO_init();
MCSPI_init();
retVal = Fvid2_init(NULL);
VpsInitParams_init(&vpsInitPrms);
vpsInitPrms.irqParams.vipIrqNum[0U] = CSL_INTC_EVENTID_VIP1INT0;
vpsInitPrms.irqParams.vpeIrqNum = CSL_INTC_EVENTID_VPEINT0;
retVal = Vps_init(&vpsInitPrms);

//my vin2a initial function unfolding
Fvid2_create
..................
//
appTasksCreate();
BIOS_start();
return (0);
}
///////////////main code over//////////

Now the problem is that an error occurs at Vps_init: No source available for "do_AngelSWI(int, void *).
Is there any mistake and where?

Thanks a lot!
I succeed drving my sensor and captured frames using Fvid2 layer.
But!!!
I found that Fvid2_init will not succeed unless PRCMs of VIP1/2/3 and DSS are all enabled.
What if only vin2a is used in my product? Obviously enabling VIP1/3 and DSS will increase the power consumption. So can i disabled other vip slices and dss after fvid_init?
