AM1806 CPU 上电后，CCS 连接出错，出错地方0x0000000c

AM1806  CPU 上电后，CCS 连接出错，出错地方0x0000000c，系统采用RBL 引导uboot.bin(uboot 加上AIS头)。其中启动运用SPI flash. 请问

1）0x000000c一般由什么问题引起的？我们需要做什么检查？

2）SPI flash中存储uboot.bin,kernel,fs. uboot.bin是否必须是从flash的0地址开始存储？我们从《Using the AM18xx Bootloader》中发现这样一句话The SPI flash device must use 24-bit addressing, and its read command must equal 0x03. The

bootloader will look for an AIS image at offset 0x00000000.。
