HI3516A boot烧录问题

我们的HI3516A板子，刚生产回来，目前可以用Fast boot烧录。但是烧录完毕完毕后会不断的打印“20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 0A”，而无法进入SPI FLASH模式。

烧录信息如下，也就是说3516A芯片是可以找到SPI FLASH的，也可以对其进行烧录。如果用开发版进行试验的话，开发板在没有进行烧录之前，只会打印一次“20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 0A”。

目前的boot模式，我们选择的是Enable BOOTROM模式，SPI FLASH模式。不知道有没有人遇到过，海思系列芯片，没有烧录前，不断打印“20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 0A”信息的。不管我们是不是采用POR模式，效果都一样。
