DS90UB948-Q1: ds90ub941->ds90ub948->touch screen, touch screen problem

Part Number: DS90UB948-Q1

Hi, Ti engineer:

My current project plan is ds90ub941 (port0 is enabled) -> ds90ub948 -> dual lvds screen (including i2c touch screen)

How to configure to detect the touch screen connected to ds90ub948? I tried to configure the 0x07 and 0x08 registers of 941, and also configured the 0x08 and 0x10 registers of 948, using

i2cdetect -y 17 is not detected.

In addition, I want to confirm that the RST and INT pins of the touch screen should be connected to those pins of ds90ub948.


The RST and INT pins of my touch screen are connected to gpio0 and gpio1 of ds90ub948, right?
