POD mode not working

My employer wants me to use an MC68HC912B32 as a masterboard in order to program other HCS12 boards.  In order to do that, I must use POD mode. However, for some reason, POD mode is not working, even when I set the PADs to the correct pattern ("10"). I have read on the Internet that in addition to the MCU being mostly obsolete as of now, Codewarrior (5.0) no longer supports POD mode. Is this true? And if it is, does anybody know the software needed in order to utilize POD mode and download the assembly code from the computer, through the masterboard, and to another board?

 

P.S.: I have heard that earlier versions of Codewarrior can access POD mode. Is this true, and if it is, does anyone know where I can download them, since I don't think you can buy them anymore?

I think you need debugger, that is able to talk to DBug12 debugger. I think yes, some olded versions of CW had support for DBug12. You may try NoICE debugger www.noicedebugger.com , it should still support DBug12

I should point out that I'm using a USB BDM multilink in order to download/debug code into the evaluation board. I'm aware that even if I had Codewarrior 3.1, the multilink would not work with it. I'm not sure if NOICE will work with the multilink or not.

 

However, if POD mode can't be used with Codewarrior 5.9, then how does code become downloaded/debugged into external MCUs? Is there an application that allows you to do it? Do you download it directly (I don't think you can, because the external board is a run-of-the mill PCB)? Is there another application?

 

I think the biggest question I'm asking is, if Codewarrior gave up POD mode, what did it replace it with?

As far as I know old CW's support LPT port multilink and doesn't support USB-ML-12. NoICE supports all multilinks. Download evaluation copy of NoICE and see.

 

I thought you were trying to use evaluation board in BDM POD mode, not multilink as a BDM POD. Evaluation board with Dbug12 in flash could be used with older CWs as a BDM POD to debug code on other boards. I took it as if you were talking about this. Of course all CW versions support debugging over BDM. It is not called as a POD mode. BDM POD is a device, which is used as a converter between BDM port (BKGD pin, RESET pin, GND and VCC pins) on your targed board and PC, as an PC adapter for BDM port. USB-ML-12 is USB to BDM "converter". Evaluation board with Dbug12 installed and jumpered to POD mode is RS232 to BDM converter. Hope it is more clear now.
