Hi,
My producs has LCD whch is drived through MIPI-DSI.
Some products failed display the LCD due to lack of header packet "Data ID" on the MIPI data lane.
Although I store the correct data to the "Packet Header FIFO Register(MIPI_DSI_PKTHDR)" .
This problem is more likely to occur at higher temperatures.
Is there any workaround?
Thank you for your reply.
I think it is diffficult to reproduce on nxp imx7d board, because this issue does't occur with all products.
I have already produced our products over a thousand units, but only 4 products have this problem.
I found that this ploblem depend on the timing of enabling 'CLK_LPCG_MIPI_MEM_PHY'.
So that I will check the clock route tree of MIPI and LCD modules.
Can you think of any reasons?
