Hi NXP engineers,
I'm working on porting ST7789V, which using 8080 interface(16 bit) to transfer data with imx7d.
My developing environment is: u-boot(2020.04-00210), kernel(4.14.98-00322).
I referred to the NXP’s patch package during the transplantation process from https://community.nxp.com/t5/i-MX-Processors-Knowledge-Base/Patch-to-support-MPU-8080-LCD-on-iMX6UL-...
This installation package does support my debugging a lot, but not everything is fixing with my product. Currently, I am still debugging in uboot. I found that my image data stopped after sending one frame, that is, it stopped transmitting after sending 320x240x2 (RGB565) data.
I am using the same frambuffer address in the LCDIF_CUR_BUF and LCDIF_NEXT_BUF registers. When I change the image data in the address, no image transfer occurs. How to solve the above problems?
In addition, I noticed that the input image format used in the uboot patch package is YCbCr422, and I have changed it to RGB16.
Regards,
Patrick.
