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?
could you reproduce this on nxp imx7d board? if yes, pls tell me how to reproduce this
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?
I didn't find this issue before, if couldn't reproduce this issue on nxp board, it's hard to tell the reason
