MC13213 EVK - Embedded bootloader - Download apps without BDM programmer?

[CecchiSandrone]

I'm starting to develop with a MC13213 EVK. I read on manual that apps can be downloaded to the device without using a BDM programmer. To do this I followed instructions over the manual: 1) Download embedded bootloader on device with hiwave.exe 2) 4 Button + Reset sequence to activate flash programming (4 led on) 3) Download .s19 file via USB connection with test tool. The problem is that after the first time I can't do the 2) step to download other apps and as a consequence I receive message "Timeout waiting for download firmware to complete", maybe because the device isn't ready for flash programming (4 led off). Any suggestion?

Thanks for help.

Embedded Bootloader from Test Tool is obsolete and Freescale don't provide support for it. Try to use BDM for download the applications to the boards.

You can try to read application note AN2295: http://www.freescale.com/files/microcontrollers/doc/app_note/AN2295.pdf and will find how to download an applications without using BDM.

Ok thanks . However the developing using bootloader could be faster than BDM. In fact with a USB Hub you can connect more devices at the same time and deployement of your code more faster. I hope Freescale will find a good solution for the bootloader's use.

Well, if you are talking high volume production, the EVB was never intended for that anyway.

P&E makes a device that will store the code, serialize (that is create a unique serial number for each unit) and set the protection keys. With some software about 500 USD.

I don't understand exactly...can you explain better JimDon?

[JimDon]

Well, if you follow the link you will find that there a specific devices available at a low cost for high speed programming of these chips.

[CecchiSandrone]

It seems that the correct button sequence to activate bootloader is: SW2 + SW4 then Reset, release Reset and then all others. The problem now is that while downloading the .s19 I receive "Firmware download failed - mismatch found on address=0x1600".

Notice for reader following this thread.

The CodeWarrior loading error is handled in
 How to generate automatically s19 with burner in the CodeWarrior board.

Cheers,

I think that the problem is the custom application must be developed bootloader-oriented. So not all generic s19 apps can run with embedded bootloader.

[JimDon]

Any chance you over wrote the Bootloader?

If you go back an perfrom step 1 again (i.e. put the boot loader badck with the BDM) does it all work ?

[CecchiSandrone]

Yes, obviously but the advantages disappear then. I would download my applications using embedded bootloader so I mustn't use the BDM (it's easier and faster I think).

[JimDon]

ok, so now we at least know the problem - the downloaded code is perhaps over writing
the bootloader or perhaps the boot loader erases part of itself.

I would submit a service request on this.
