I need some help in clarifying some stuff.=20 I am interested in booting uClinux in a palm pda from a memory card.=20 I was reading abt an article abt Using Flash Memory with uClinux at http://www.cyberguard.info/snapgear/tb20020917.html Does this Flash Memory mentioned includes MMC and SD? I checked out MMC and found that it uses Flash technology for read and write operations. For SD, it is a flash memory storage device. Can I conclude that it is able to work for SD card regarding the part " booting, running and operating from a flash memory regardless of the processor" ?? What abt MMC since it uses the same technoloy? Flash Devices include SD and MMC? I am abit blurz about this Flash memory terms in the article. It includes too much technical terms like NAND and NOR FLASH which I have difficulty in understanding in a short period of time. cheers Dingyao
