IAREW reports: Can't run to "main"

[kai_liu]

I am evaluating AN2295 serial bootloader on FRDM-KL25Z with IAREW650.

Before debugging, I change debugger to PEmicro - OpenSDA, nothing more. When I start to debug, the IAREW reports: Can't run to "main".

And it has no main(), it has only __main().

What else should I change to debug the AN2295 code?

Hi Kai,

First, you have to set the correct debug interface , for example, like below:

and you have to select the proper flash loader:

With the above settings, you may start to debug the AN2295 demo.

BTW, please kindly install the OpenSDA patch for IAR in the attachment.

Hope that helps,

Hi, Kan Li,

Thanks for your information, here is my update for this issue.

Change Debugger to PEmicro

Enable Debugger download options. (Very important, it seems the root cause)

Change P&E hardware interface to OSJtag to OpenSDA (it seems we don't need the patch, since EWARM 6.50 has  supported OpenSDA already).

Start debug session.

It reports same issue as well.

Then I changed run to main as run to '__main'.

No complaints.

When there is no user application in the flash memory, the bootloader seems always come back to __main. I will evaluate this operation with a simple user application.

Thanks for your support.

Currently, my project for KL25Z interface to Android device (GAP, as Generic Android Perpheral) is almost finished. I am trying my best to make it a complete solution available to market, with bootloader (UART and USB MSD in future), demo firmware and demo application on Android, as well as necessary documentation.

I hope to get more support from Shanghai office.
