I want to use a 32Mb SDRAM to redirect the frame buffer of the GUIX graphic controller on it.To do this I have validated the External BUS in 16bits SDRAM mode, (this will be the only component that will use this external bus).The SDCLKout is On (120MHz).To validate the SDRAM operation, I created a section "MySectionSDRAM" in the fsp.ld file, and created an array in this section:
When I write in this table, I always read back 0.
So I must have forgotten a step for SDRAM initialization, but I can't find an example.
I don't see where I can check or change the timings if necessary?
I use e2studio 2021-04 with FSP 3.1.0
Thanks for your help,
Last problem solved too!I had forgotten that the GUIX Stufdio project was defined in 16bits RGB...
Presumably you confugured tge SDRAM in E2 studio? Is this your own board or a dev kit?
yes I use e2Studio for RA6M3.
I managed to validate the SDRAM by doing a SDRAMInit function at the input of my system_thread.Finally it works well for my test table, but now I have a problem with my graphics controller.
The format for the SDRAM is not correct, the image is doubled and "monochrome"... I configured my GLDC with format RGB 32bits 8888, SDRAM 16bits...
I will try to fix this problem.
Eric Hello Mr. Eric, I'm Mahmut Kocaman. I am an embedded system software engineer in Turkey. I'm new to Renesas processors. That's why I want to consult you about something. I'm trying to drive a 7" screen with a RA6M3 processor. I'm trying to do this on the segger emwin platform. I couldn't find a source for both GLCDC and external SDRAM configuration in E2 studio. Can you help me with this?
