D-BUG12 and 9s12

scientist — Sun, 29 Jun 2008 11:25:41 GMT

hello, I am from mexico, peninsula of yucatan, so I am sorry for my english, my question is, if I need programming DBUG-12 in to the microcontrollers 9s12 our If already they have it of factory the DBUG-12?
if don´t understand iam sorry

Hello

DBUG-12 is already programmed in some off the self boards with S12, but not in every chip that comes out of the factory. I use an elektronikladen board and it was not programmed, however, some other assembled boards / modules have it programmed in order for the user to be able to load code into MCU... It functions as a bootloader in general (it loads code from PC, flashes it in memory and runs it).

So, if already have a board check the manual for DBUG.

hi, thanks for answering me, the questions is I wanna construct my own board, and I want buy the 9s12gc32, the freescale don´t sale the Mcu with D-BUG12? if don´t, I need a POD for programming the DBUG-12 in to the MCU? Thanks again for your attention

AFAIK dBug12 needs more than 64k of flash. No way to fit dBug in GC32.

so I am confused, because I have a board with the 9s12gc32, and I use the special single monitor with Code Warrior, what I need to work with that option? I think that was needed the DBUG-12 to work special single monitor, waht I needed? a firmware BDM to work? The 9s12 already come with this firmware?our I need a POD for programming the micro?

I´m sorry for my bad english

Hello.

Yes you need some kind of BDM POD to program MCU chip. However, since you 'll have a pod i think you DON't need DBUG 12.......

Re: D-BUG12 and 9s12

nikosxan — Mon, 30 Jun 2008 23:11:40 GMT

BDM involves some specific MCU pins / ability form loading program to MCU etc. and specific external H/W (pod) to do the job. Sometimes they put inside the MCU some S/W means to do the job (at least similar job), as is the DBUG 12.

When you say firmware BDM you mean hardware ???

You want to go to production ? (program some MCUs with a program you developed ...)

-DBUG-12 will not fit in a 32K part.
-DBUG-12 is not really useful for development, as you are limited to RAM and whats more POD mode is not supported in CW anymore.
-DBUG-12 is not really supported at all by Freescale.
-Unless you were buying a POD board from freescale, which I don't think freescale makes anymore, DBUG-12 was never programmed into a chip. It was always up to the board manufacturer to do that.
-You want a P&E USB Multiink to program you board. You could buy a DBUG-12 POD, but it will not support new chips, and you have to use the serial port instead of the CW GUI. And you will not really save much.

Bottom line, forget about DBUG-12, and get the P&E Multilink. It is will supported.

hello, thank you very much for all his answers, that help me a lot for information, so, I need a POD for programming a microcontroller of the family 9s12xxxx for programming in the mode monitor, so other questions, (a lot of questions ) in my board that buy used the 9s12gc32, in the specifications says that have a programm monitor that occupies 2k in flash, with the POD I can programme the microcontroller and then make my board with this programm monitor, They can recommend me a card to buy? thanks again

and again, sorry for my bad english

Re: D-BUG12 and 9s12

One last try:

Do NOT buy a pod.

Buy a P&E USB Multilink.

Re: D-BUG12 and 9s12

scientist — Tue, 01 Jul 2008 02:44:53 GMT

ok, sorry, thanks, and can you recommend a board of the 9s12?

Re: D-BUG12 and 9s12

nikosxan — Tue, 01 Jul 2008 02:46:13 GMT

What brand is your board ? Do you have an internet link for that ?

Yes, some board manufacturers do put a small monitor program (such as DBUG) to help you start with your board without a need for extra H/W as pod. However, not all functionality is always there. I should not consider it pro tool. Again, what do you want exatly to do and you need to buy MCU with monitor pre-programmed ?

scientist — Tue, 01 Jul 2008 03:09:26 GMT

yes, I am from mexico, and buy that board in the http://www.racom.com.mx/desarrollo.php but the page is in spanish, and my doubt was if freescale sale the MCU with that program monitor in the flash? thanks again

Are you talking about at factory flashed LRAE bootloader firmware? No, all parts come blank from the factory.

Old MC9S12DJ64 Device User Guide V1.20 says "It is planned that most HC9S12 devices manufactured after Q1 of 2004 will be shipped with the S12 LRAE programmed in the Flash". Unfortunately or fortunately these plans weren't ant won't be realized.

If multilink is too expensive for you, then maybe build TBDML. Good luck

thank you very much kef, can you put some link about that programmer?

Re: D-BUG12 and 9s12

kef — Tue, 01 Jul 2008 14:57:37 GMT

I'm using Multilink and my own programmer mostly, so I'm not sure if this isn't outdated:

TBDML forum may give you better answers:

The TBDML does not work correctly when the PLL is engaged.
It will not show the registers under these conditions. It is unsupported.
You will probably be able to burn flash, but may find it is not worth the effort if you need to debug.

hello, a partner tell me that the mc9s12ne64 already have a firmware with bootloader, its that true?

he showme a article thats says that, but better I ask you first

hello, looking in other forums I readed this

Hi Nick.The Softec on the AK-S12NE64-A board, there is a daughter board called CM-HCS12NE64 where you can find the NE64 chip.On this daughter board, there is also a BDM port. You can you any BDM pod/cable and any software interfacing this BDM pod/cable to download code and debug an application.As you noticed, the chip is factory flashed with a Monitor talking via the Serial/COM port to debugger/software that support the Monitor (HCS12 Serial Monitor), this to get an immediate debugging support without buying any BDM pod/cable.But if you debug via BDM with pod/cable, you can fully erase the chip and get rid of the Monitor.Regards,Gilles

" in a page called osnir, please, let me known what you think about this, thanks

again, sorry for my bad english

Ok. Thank you. I am aware of somw US boards that DO come with flashed monitor for serial load / flash program.
