本人使用ICE板的etherCAT例程时，在把ethercat_spi.bin烧录到SPI flash时，会出现奇怪的情况：
[CortxA8]
[CortxA8] AM335x ISDK Flasher Version - 1.0.5
[CortxA8] Enter the board type [0-ICE, 1-IDK ]
0
[CortxA8] SPI id selected - 0
[CortxA8] Manufacturer ID read is 0xef.
[CortxA8] Device ID read is 0x16.
[CortxA8] Enter the binary type [0-Bootloader, 1-Other ]
1
[CortxA8] Enter the Offset in bytes (In HEX. eg:- bootloader :0x0 app : 0x20000)
0x20000
[CortxA8] Load .bin file to 0x80100000 and Enter 0 to continue
0
[CortxA8] Flash erase offset = 131072 , length = 167936
[CortxA8] Writing...
[CortxA8] Verifying...
[CortxA8] Did not match @ page 213, bytes compared : 256. Exit
出现这种情况（三次），烧录正常。输出LED灯会来回点亮，EtherCAT通信正常。
而经常出现的情况是，最后一行出现的是[CortxA8] flash done ，此时烧录的程序居然不正常。只有4个LED灯会亮，EtherCAT不能通信。
使用的都是同一个bootloader和etherCAT的bin文件烧录，怀疑是烧录过程哪里出现了问题。JTAG的频率也从1Mhz，调到500k到200k都试过，依然出现同样情况。恳请指导！！
下面是烧录过程中会碰到的两种错误情况。
