I am working with MCIMX6SLEVK - SoloLite EVK.
A separate board having EPD with MODEL NO. : ED060SCM (Display + Touch) is connected to the EVK via EPDC Expansion Port. The setup works well when the Touch panel is not connected. Whenever the Touch Panel is connected , the Board crashes while booting.
EPD Touch Details:
"The touchpad controller is defined as a slave device of I2C and the host is defined as a master.
The device address of the touchpad controller is designed as 7-bit address format. The touchpad
controller address is defined as 0x20 as shown below.
The 7-bit Addressing defined as shown below:
Bit 6 Bit 5 Bit 4 Bit 3 Bit 2 Bit1 Bit 0 (LSB)
Address 0 0 1 0 0 0 0
According to the 7-bit addressing, the first byte after the Start procedure is shown below:
Bit 7(MSB) Bit 6 Bit 5 Bit 4 Bit 3 Bit 2 Bit 1 Bit 0 (LSB)
Address 0 0 1 0 0 0 0 R/W
The first seven bits of the first byte make up the address and the 8th bit is the LSB (least
significant bit, R (Read) = 1 and W (Write) = 0)."
Also , other than Power , Ground and I2C , 2 more signals interfaced with Touch panel are :
EPDC_PWRCTRL3 , pulled up to 3.15V using 4.7KOhm.
Using EVK Binaries provided with the kit. Also the working and error reports as well are attached.
