Original question:
we are using process-sdk-linux-am335x-06.00.00.07,how to solve the above problem
Hi user4927006,
Do you use AM335x TI board or custom board?
Can you put your boot up log in txt file and attach this file here?
Regards,
Pavel
Hi Pavel Botev,
We are using custom board

Hi user4927006,
You might need more LCDC memory bandwidth. Please refer to the below e2e threads for details:

Hi,Pavel Botev
I tried
#define EMIF_OCP_CONFIG_BEAGLEBONE_BLACK 0x00141414
#define EMIF_OCP_CONFIG_AM335X_EVM 0x003d3d3d
but did not resolve my issue.
My DDR3 is cutom,please let me know how to get a correct .ocp_config value
Hello,
For settings AM335x EMIF optimal values, please refer to the below pointers:
Regards,
Pavel
