我看到AM3352的datasheet描述(红色字体)
26.1.6.1 Overview
The Fast External boot feature:
• Consists of a blind jump in ARM mode to address 0x08000000 in an external XIP device connected to
CS0
• The jump is performed with minimum on-chip ROM Code execution (only configures GPMC interface),
without configuring any PLL
• Allows the customer to create its own booting code
• Is set up by means of the configuration pins, see Table 26-7.
• Addr/Data muxed device or a non-muxed (selected using SYSBOOT[11:10]) device in connected in
XIP_MUX2 configuration
• Bus width selected by SYSBOOT[8]
• CS0 chip select
• No wait monitoring is available
我用的是 Fast External boot 的XIP_MUX2模式,在ROM CODE期间只配置GMPC 接口,我想问一下是不是只配置了Table 26-9. Pins Used for Non-Muxed NOR Boot中的引脚啊?
即是不是指配置如下管脚:LCD_DATA0、LCD_DATA1、LCD_DATA2、LCD_DATA3、LCD_DATA4、LCD_DATA5、LCD_DATA6、LCD_DATA7、LCD_VSYNC、LCD_PCLK、LCD_AC_BIAS_EN。请技术支持指导下,谢谢!
