Hello,
I'm new on this forum and I'm interrested with this µC. I'll probably design a custom board for future project (or only for my own).
Concerning the LCD RAM buffer, it's stated in the doc "AT91SAM9 LCD Controller" that if LCD Frame Buffer and Application are in SDRAM there is a lowering on performance. If the LCD frame buffer is on the SRAM and application in SDRAM (or vice-versa) it's ok. This for a question of access to the external memory.
I'm wondering if one can use both SDRAM without lack onperformance if the port EBI0 is used for the SDRAM application and the port EBI1 is used for the SDRAM LCD frame buffer.
Is it correct?
Regards
