Bootloader problems

[wangb]

Tower_bootloader downloads into the chip.

1.How does the chip determine whether to enter the bootloader or the user program?I'm using the KV30.

2.Can the TOWer_bootloader program be debugged using JLink?

Hi Wang,

1. Please refer to Kinetis Bootloader v2.x.x Reference manual. 

Figure 2-1 shows the start-up flowchart.

2. Yes, of course.
