I finally solved my problem!
Components connections are shown in my attachment.
I set the pixel_buffer "Default Buffer Start Address" to the base address of the SRAM (0x00900000). Plus, I added the Alpha_blender so I can display both source at the same time on my monitor. char_buffer is displayed as foreground and pixel_buffer as background.
pixel_buffer is configure to work in 320x240 (width factor: 2, height factor: 2) and color space is 16-bit RGB.

instead of sram, i use sdram as the buffer. i have set the "default buffer start address" to the base address of the sdram too (0x00800000). i have checked all the fpga pins assignments and they are all connected as they are supposed to. but still i cant display anything on the TRDB_LCM. did you store the pixel value to sram first before you use the funtion alt_up_pixel_buffer_draw()?? i've tried to write the color values to sdram first then i tried using the function after that. but still i cant display them. what's wrong actually?? this is frustrating me
