自己做的板子,想从nandflash启动,把MLO和u-boot.img烧进flash,改从flash启动,启动信息如下
U-Boot SPL 2011.09 (Dec 31 2012 - 15:52:36)
Texas Instruments Revision detection unimplemented
Could not read the EEPROM; something fundamentally wrong on the I2C bus.
read_eeprom() failure
payload image: U-Boot 2011.09 for am335x board load addr: 0x807fffc0 size: 363512
image entry point: 0x80800000
从启动信息来看,貌似已经把u-boot拷到了内存0x807fffc0处,跳过header之后的入口点是0x80800000,可是执行到这里就不动了,跟踪了一下发现程序执行到了spl.c的jump_to_image_no_args(),在这个函数里执行了image_entry();然后就不动了,请问这是什么原因?难道MLO没有把u-boot拷到内存么?
