Kinetis K60 bootloader for Keil uVision

[waynelai]

The application note for Kinetis K60 bootloader "AN4368", "AN4370", "AN4379", "AN4605".

There are no example for Keil uVision.

Does Freescale have updates for Keil uVision support ?

Thanks.

Hello Wayne:

The appnotes you mention use USB as the bootloader interface. But you may want to give a check to AN2295, which includes projects for Keil uVision. This bootloader uses a serial UART interface.

Hello Jorge Gonzalez,

I've downloaded an2295sw.zip to build with Keil uVision4,

but a warning message as below.

.\Kinetis_K_100MHz\AN2295_KinetisK_100MHz.axf: Warning: L6305W: Image does not have an entry point. (Not specified or not set due to multiple choices.)

I've read the an2295.pdf, but it does not mention about the Keil uVision.

Does it matters ?

How to fix ?

By the way, does .hex format can be used with serial bootloader ?

Thanks.

Regards,

Wayne.

Hello Wayne:

I have not used Keil much, but according to the message the linker is missing a reference to the entry point. However, seems that the project already has a vector table with "__main" specified, so I think there should be no problem with that warning.

As for the hex files, you cannot use those. The PC bootloader tool specifically asks for a S19 file.

Hello Jorge Gonzalez,

So the hex file, we need to use tools to generate to S19 files.

Where can I find this tool ?

Thanks.

Hello Wayne:

How are those Hex files generated, by Keil?

So far I never had to do that conversion (hex -> srecord), so I do not know of a specific tool, sorry. But I guess you can find some options searching in the web.

I have only used Burner utility that comes with CodeWarrior, but it seems that this only applies for the opposite procedure (srecord -> hex).

Regards!
