Hi Ti experts:
On our custom boards , SoC is TDA4VEN . There are three deserializers connect to SoC's capture inst0, inst1,inst2.
In this link , I met the ``UDMA open failed `` error when I try to use capture instance 2.
And , TI experts told me that , add the following code to `app_csi.c` . After that , No error shows in Drivers. Sadly after running multi_cam demo , It still stuck at dequeue.
To find out why , I done some tests :
Firstly : using csirx test case provided under mcu_plus_sdk_j722s_09_02_00_41/examples/drivers/csirx/csirx_capture_testapp/j722s-evm/main-r5fss0-0_freertos/csirx_capture_test_main.c
I modified the code to support openning three capture instance simultaneously,
I only connected one camera to one capture instance once a time. And tested three times.
result is :
From the csirx test case , I assume that driver of third capture instance work properly.
=======================================================================================================================================
1. CRC , ECC error existing in drivers is normal ?
2. Where else should TIOVX code be changed to support the third instance ?
