TDA4VM: The A72 application trigger is not receiving image data sent by MCU2_0

Hi Yang,

Sorry, could not understand the exact issue. 

- You are using OpenVX framework to receive data over CSIRX on mcu2_0.

- and then received data is sent to A72, how are you sending this data to A72? Are you using graph parameter to get this data on A72 application? How do you know/determine in this case that trigger is not received? and when/how do you reboot?

hi ti

We are using the OpenVX framework, the data source is mcu2_0, and the application receives data through CSIRX.

No image data was received after 1915.331697 s.

Hi Yang,

This most likely means CSIRX has stopped outputting data or R5F is stuck somewhere. When this happens, can you please connect to mcu2_0 core using JTAG+CCS and see where R5F is?

hi TI

The probability of this fault is extremely low. We are not capable of reproducing and analyzing it. Based on your previous experience, how should this problem be solved?

Hi Yang,

its difficult to say the reason for this stall, unless we have some more data.. So next time when you see this error, can you please capture atleast capture statistics? and see if it is dropping frames or still capturing frames?

hi TI

How do we obtain these capture statistics? Are there any good methods?

Hi Yang,

Since R5F seems to be getting stuck, the only other way i can think of is to connect R5F, load symbols and see capture objects from CCS expression window. This will tells if capture is still running and is it dropping the frames..
