大家好，
最近在AM335x BeagleBone Black 上完整验证了下eMMC的烧写，总结了一篇文档共享出来，欢迎拍砖。
附件是文档中所描述的debrick.sh，烧写用的文件系统在后面的跟帖，这篇帖子可以和“AM335x Flash Tool -- UniFlash 烧写工具使用简介及问题解决方案汇总”互为参考。
Hi Jian工 您好~
請問我燒錄完後都會出現下列訊息,似乎是敘述空間不夠需要刪掉程序...等等

## Partitioning the eMMC using information gathered.
## Here is where you can add/remove partitions.
## We are building 2 partitions:
## 1. FAT, size = 9 cylinders * 255 heads * 63 sectors * 512 bytes/sec = ~70MB
## 2. EXT3, size = 223 ($CYLINDERS-[9 for fat]) cylinders * 255 heads * 63 sectors * 512 bytes/sec = ~1l.7GB
##
## You will need to change the lines ",9,0c0C,*", "10,,,-" to suit your needs. Adding is similar,
## but you will need to be aware of partition sizes and boundaries. Use the man page for sfdisk.
