Hi there people.
I'm a bit confused on the touchscreen I2C pins being used.
If we look at the wiki we find:
I2C-1 0x38 – focaltech touch
I2C-1 0x54 - EEPROM On carrier
I2C-1 0x55 - EEPROM On carrier
I2C-2 0x1A – audio codec
I2C-2 0x50 - EEPROM ON SOM. Don't change!
I2C-2 0x51 - EEPROM ON SOM. Don't change!
But if we look at the schematics of the carrier board we can see that the Touch Connector is routed to signals I2C2_SDA and I2C2_SCL.
Besides this if we look at the DTS files in the linux files we see that the touchscreen controller is associated to I2C2:
.... (audio codec related dts parameters)
..... (touchscreen related dts parameters)
So I guess the Wiki is wrong.
Can you please confirm this please?
There's a similar issue with the eeprom on carrier mentioned in the wiki. I guess this refers to the BOARD_ID chip mounted on the carrier board which says the address is 0x52 & 0x53 which doesn't match the address mentioned in the Wiki. Am I right?
Can you please advice?
