各位大佬，请问 AM3354 与 AM3358 外搭 RAM 与 ROM,最高各能支持到多大容量？
看数据手册写的有些模糊，特来请教。
? ? 说：外搭 RAM
请问具体指的是什么RAM? DDR3?
? ? 说： ROM
具体什么ROM? SPI flash? nand flash?
外搭RAM值的是DDR3，ROM指的是EMMC/nand flash
DDR3最大支持1GB。
NAND flash数据线和地址线是复用的，理论上没有大小限制。但如果选择从nand flash启动的话，ROM对nand flash有要求。具体请看下面的TRM文档26.1.8.4 NANDhttps://www.ti.com/lit/ug/spruh73q/spruh73q.pdfemmc大小也没限制，请看下面帖子。https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1072696/am3352-what-is-the-maximum-size-that-emmc-can-support
