Hi,
We have a custom DM8148 board with tvp5150 connected to VIP0 Port A. When capturing an image for the first time after reboot, I always get the following stack dump.
The stack trace happens only the very first time, and doesn't happen again afterwards.
Q1: Why does this happen?
Q2: Is this something I need to be worry about?
We use EZSDK 5_05_02_00. The trace occurs somewhere in:
ti81xxvin_main.c / ti81xxvin_buffer_queue() / ret = inst->captctrl->queue(inst->captctrl, vb->i);
Thanks,
tamo2
