beaglebone本身是tf卡启动的
参考beaglebone做的板子,但把tf卡换成emmc,因为两者的接口是一样的。
比如先用jtag连上板子,把读写tf卡的程序载入内存,运行这个程序也就是把mlo和app载入emmc,这样做可以吗?
是否需要在starterware上做些修改呢?

你这个替换操作需要注意下面几点:TRM手册的26.1.7.5.2节。
Each interface has booting restrictions on which type of memory it supports: -
• MMC0 supports booting from the MMC/SD card cage and also supports booting from
eMMC/eSD/managed NAND memory devices with less than 4GB capacity.
• MMC1 supports booting from eMMC/eSD/managed NAND memory device with 4GB capacity or
greater.
>给emmc烧写程序,和从emmc启动,这两个操作有什么需要注意的地方
你是想问怎么烧写emmc么?在Linux部分的操作,可参考着BBB emmc的烧写的脚本来做。注意从MMC1改到MMC0

你好,
请问你有遇到过starterware包通过sd卡boot不起来BBB的情况吗?我用的是最新的starterware,并patch了,但是把MLO和app copy到sd卡,启动还是ccc.

您有仿真器吗,可以连上去debug下,看看哪里停住了
