CC3200 烧录/sys/mcuimg.bin 文件时，使用CCS UniFlash 烧录时 提示ERROR: Open operation failed

如题，CC3200 烧录/sys/mcuimg.bin 文件时，使用CCS UniFlash 烧录时，提示ERROR: Open operation failed，但bin文件如果小一点又可以烧录进去，而且程序正常运行，说明flash的读取是没问题的，唯一区别就是 bin文件过大（原来160K，大一点170K）就提示R: Open operation failed，之前怀疑是FLASH大小不够，由1M换成2M，仍然出现该问题，请工程师们解答一下呢，谢谢

    确认一下，再烧录bin文件之前，有没有先格式化再操作？

    没有先格式化，因为除了/sys/mcuimg.bin，还有其他的一些网页文件，所以我是以替换/sys/mcuimg.bin方式进行的，这个是不是存在问题呢，问题是出在哪里呢？
    这是出错的日志

    就是没有格式化引起的问题，烧录之前需要格式化，网页文件可以后续通过application binary再烧录进去
