I have i.MX6 Ultralite. I have connected 7" RGB display with touch and communication protocol is I2C.
Linux has installed. I want to change display mode from landscape to portrait.
you could use GC320 low level API to rotate (if use linux frame buffer). It implies a blit but it would be done by GC320 they will probably need to use virtualFB too.
The API documentation is the BSP documentation (iMX6.2D.API.pdf)
Attached a simple source using the 2D low level API.
Is GC320 low level API can rotate touch panel ?
The driver used for display id fbcon and for touch panel edt-ft5x06.
I didn't test this, this suggestion is from R&D team, you can try it if you use linux frame buffer, I post the 2d simple source code for reference.
