lunux-AM437X-EVM-02.00.01.07 Processor SDK -touchscreen is unresponsive

Tingting Zhang

I downloaded ti-processor-sdk-linux-am437x-evm-02.00.01.07-Linux-x86-Install.bin and run it on AM437X EVM,but I found that touchscreen is unresponsive ,and only use mouse to navigate. but I run ti-processor-sdk-linux-am437x-evm-02.00.00.00-Linux-x86-Install.bin on my AM437X EVM and found both touchscreen and mouse are responsive. i powered off/on board for several times and got same result. I wonder if the ti-processor-sdk-linux-am437x-evm-02.00.01.07-Linux-x86-Install.bin doesn't support the touchscreen navigation?

Hi,

Do yo have any related errors in the boot log? Can you share it?

I don't have am47xx board to test this. But enabling/disabling of touch screen & mouse pointer is done in /etc/init.d/matrix-gui-2.0. Have you compared the script in the two sdk releases 2.00.01.07 & 2.00.00.00?

Best Regards,
Yordan
