Hi, I'm using ADV7619 on my board, in pair with my FPGA/FreeRTOS/XilinxSDK, I'm also using the evaluation board EVAL-ADV7619-7511.
I'm testing it with 12 different Set Top Box devices from different vendors. I'm able to get a signal lock on every single of them.
The only device I'm having trouble with is the Quantum Data 804B Signal generator.
The scenario is as follows:
MY device with ADV7619 is booted/powered, with cable already in HDMI PORT A , connected to an ALREADY RUNNING Quantum Data 804B Signal generator with settings 1080p@60/
This causes the following symptoms:
ADV7619's interrupt pin and register IO->0x3F (INTRQ_RAW) continually signal new interrupts, stating that CABLE_DET_A_RAW is 1
ALL other required RAW registers are 0 (t PLL LOCK RAW = 0 , TMDS CLK RAW =0, DEREGEN = 0, STDI_DATA_VALID =0, V_LOCKED=0)
If I plug the HDMI cable in and out, a few more interrupts later I get PLL LOCK RAW 1 , TMDS CLK RAW 1, DEREGEN, STDI_DATA_VALID 1, meaning the signal was locked.
I'm using the latest recommended script configuration files when configuring the ADV7619 on my device.
The EvalBoard when booted onto a stable HDMI signal from the Quantum Data 804B Signal generator, is perfectly able to acquire a signal lock.
Could you please provide me some troubleshooting pointers or hints, so I can try to determine the root cause of this behavior?
