Hi Andy: Oh~ In Normal or suspend mode, we will have many choices for these submodules. Actually, we don't have too many time to implement these modes and verify these modes now. I think we should force on one basic normal mode and suspend mode now. Because I want GTA02 can be a real phone and we can use them to replace our mobile phones. If everyone use GTA02 to be a phone in openmoko and MC department, we can get many bugs form these users. Therefore, I suggest that the basic normal mode should have NAND FLASH, NOR FLASH, Audio Codec, Audio AMP,LCM, GLAMO3362, GSM and Back light. If we have these submodules , the GTA02 can be a phone. For a basic suspend, we turn off audio AMP, LCM, Backlight and S3C2442 ,GSM, GLAM3362,and Audio Codec enter their suspend mode. Do you agrees with me? Best Wishes Allen Chang
