How to compile Kinetis Bootloader 1.1.0 with KDS3.0 ?

[NicolasP]

Hi,

Bootloader 1.1.0 is delivered with IAR projects.

I'd like to compile bootloader for my system with KDS 3.0.

Are there some kds project files for bootloader somewhere ?

Best regards,

Nicolas

Hello Nicolas Pinault:

The KBOOT v1.1 does not have a target project for KDS, but KBOOT v1.2 is coming soon (tentatively this week) with KDS projects. Please wait for the release, you can monitor the KBOOT page:

Kinetis Bootloader|Freescale

Hello Jorge,

KBOOT v1.2 is exactly what I need. That's perfect.

I am using FRDMk22F board (MK22F51212 target).

I don't understand what are the differences between flashloader, flashloader_loader and freedom_bootloader targets.

My guess :

- flashloader : runs in RAM and is able to erase/program the full FLASH memory once.

- flashloader_loader : runs in FLASH and can erase/program the FLASH memory above a predefined address multiple times.

- freedom_bootloader : flashloader_loader for FRDMK22K board

Am I right ?

Regards,

Nicolas

Hello Nicolas,

Not exactly, read the definition in KBOOT release notes:

(C:\Freescale\FSL_Kinetis_Bootloader_1_2_0\doc\Kinetis Bootloader v1.2.0 Release Notes.pdf)

So in summary:

-​ Bootloader (tower or freedom): Bootloader firmware that resides in Flash and can be used multiple times.

- Flashloader_loader + Flashloader: The firmware you get from the "flashloader_loader" project can be programmed to the K22 with an external tool (Jlink, U-Multilink, OpenSDA,...) and you get a one-time loader. As stated in the text box, the flashloader project must be built first.

I hope this clarifies.

Hello Jorge,

That's perfectly clear. I should have read twice.

Thanks a lot for your support.

Hello Mark,

That's an interresting product. If KBOOT does not do the job, this might be a good alternative.
