AD7606问题

jinyi7016

AD7606与L138进行连接。
# s6 }' |- ~# o1 Q6 g& o直接接在了AD7606的总线上。系统无法启动动，无法加载文件系统，串口输出如下：

之前以为是CS的问题，后来再测，发现CS是高电平，目前是把CS ＼OE两个引脚者断了。还是不行。
但是AD7606的3.3V电压断开后就可以正常启动，只要是接着3.3V的逻辑电源就无法启动动。其他的5V模拟电源都是正常接着的。
8 |; y4 A2 }9 Z8 C3 x这是不是AD7606在总线上会对Nand的读取有干扰的问题？
. D! Q8 I; `# `( H+ ]5 G0 l
创龙的AD7606模块是怎么连接的，可不可以提供一下原理图。
