Kernel panic when trying to use DSI-B

Has there been any updates on this issue? I am having the same problem.

Hi Shawn_R,

We haven’t fixed the issue in TX1. We moved to TX2 and the ports are working there so we are using that one for the moment. I only found an issue with the pixel clock when defining multiple modes but we found a fix for it:

For the moment we decided to continue working on TX2 so TX1 is on hold.

Hope this helps.

Edison_F_A,

Thank you for your response. I guess we will move to TX2 also.

I am curious if you tried to bypass that crazy IO_ADDRESS macro and write a simple function to try to get a good APB memory address that would not throw an exception?

Do you know if it is calculating the IO_APB_VIRT address correctly?

Hi Shawn

I tried bypassing the macro and that removed the crash but as expected the port didn’t work. At that point we decided to focus on TX2 so I didn’t go beyond that. If we go back to TX1 and find a solution I’ll update the thread with the results.
