AM5728: rtos/VIP/VPDMA/Interrupt

wonjune kim

Part Number: AM5728

I am using AM5728 custom board.
I am using RTOS and the version is processor_sdk_rtos_am57xx_5_02_00_10.

The loopback example of "pdk_am57xx_1_0_13 \ packages \ ti \ drv \ vps \ examples \ loopback" was used to receive camera data and complete the display.
As I checked, it seems that an VIP interrupt appears at the beginning of receiving the camera data.

I want to generate an interrupt when VPDMA is completed.
The current settings are VIP2, Slice0, Port A, and FVID2_DF_YUV422P.

After checking the init part of FVID2,
retPrms-> vemEventGroup [chId] = VEM_EG_LISTCOMPLETE;
I am wondering if it is related to that part.

I would appreciate your reply.

Thank you.

Hi,

Driver gives callback only when frame is received. It does not give callback at the start of the frame..

So please use driver provided callback.

Thank you for answer.
I'll check.

Can you know the function name of the callback function called in the example?
The example I use is "pdk_am57xx_1_0_13 \ packages \ ti \ drv \ vps \ examples \ loopback".

Thank you for answer and please reply.

Thank you.
