以 Tiny6410 为例,分析S3C6410启动方式及启动流程。 S3C6410手册 03-SystemController: Internal clocks will be generated using external clock source as illustrated in Table 3-1. The OM[4:0] pins determines the operating mode of S3C6410X when the external reset signal is asserted. As described in the table, the OM[0] selects the external clock source, i.e., if the OM[0] is 0, the XXTIpll (external crystal) is selected.Otherwise, XEXTCLK is selected.
