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你好,我看到AM335xdatasheet这样介绍的(红 {MOD}部分),我目前XIP启动,并且是非复用 norFlash启动,按照红 {MOD}描述应该按照XIP_MUX2连接,对吗?GPMC_ADVN_ALE这个信号时地址锁存线有什么作用?,在gpmc不用这个线行吗?在table26-9表中看到BE1N在模式XIP_MUX2中为什么要连接GPMC_CSN2 and GPMC_BE1N?
