Hi all,
6614的datasheet(SPRS671D),
2.6.1章节,写着“With ARM as the boot master, two boot modes are chosen by the boot mode sequence. If a failure on the primary
boot mode is detected, then the secondary boot mode is attempted.”
table 2-13 ARM Boot Mode Sequence,里面每一组设置都有两种boot mode(分别为1st和2nd),我以0001组合为例,其对应的boot mode是1st=UART,2nd=EMIF16(NOR),在串口没有接线的情况下,等了好久也没见EMIF16(NOR)有进行boot(在组合1101时,这种bootmode是能正常工作的)。
问题:如何理解上面红色的句子?怎样算primary boot mode failure?
谢谢!
