FRDM-KE02Z连电脑后,出现的128M空间是怎么来的?

2020-02-11 09:10发布

FRDM-KE02Z直接连电脑,电脑上会多出FRDM-KE02Z盘,空间是128M。如果进入Bootload模式,连接电脑后会多出BOOTLOADER盘,空间也是128M。
不知道这128M的空间是怎么来?是从系统盘中虚拟出来的?仅仅为了更新程序,要虚拟这么大空间的一个盘干什么?

不过好像P&E没有开放OpenSDA的Bootloader,不知道CMSIS-DAP_OpenSDA.S ...


OpenSDA consists of the hardware design, the software Bootloader and the Applications.  CMSIS-DAP is just one of the OpenSDA Applications.  The firmware release from ARM includes a port to OpenSDA and specifically the Kinetis K20. CMSIS-DAP is supported by Keil MDK.

Additional OpenSDA Applications include the P&E Debug Application (supported by CodeWarrior, IAR, Keil, and more) and the MSD Flash Programmer.  There are more in the works including an open sourced data logger application.

有人评论说:

I have finally located the CMSIS-DAP Beta 0.01!

It appears to be a skeleton design with one concrete implementation for LPC43xx device but it's a good starting point.

However I am now a bit confused about exactly what it includes.

Is the bootloader function on the KL25 board part of OpenSDA or is it just the debug implementation that you can download to the device?

Hopefully this will become clear with some investigation of the downloaded Firmware.
