Custom Keyboard Problem

[jimmii]

Hey there,

I have a strange problem with my custom keyboard.

In the simulator everything looks and works fine. See image:

But when I download it to my target, following screen is presented:

The touch events and the active rectangle are correct and the correct values are shown in the text area. See following image:

When touching e.g number 2, the overlapping numbers disappear. See:

There seems to be a problem with displaying the numbers, the overall functionality seems to work.

Any ideas what's happening here?

Thanks a lot.

Hello @Martin KJELDSEN​ 

Quick update:

I'm putting all RW and ZI data to external SDRAM, which works perfect for me and I didn't have any problems.

But the Keyboard causes problems with this configuration as described above.

After moving the Keybord Configuration to interal ram (RW and ZI) the Keyboard is working fine as expected.

Any idea why this is a problem? Maybe you can reproduce this behaviour at your end?

External sdram configuration and initialization is well tested and is working in other parts of the code.
