Hi All, We are soon going to send some HCS12 modules (9S12D64 and 9S12H256 based) out for field testing. It's easy to e-mail new code to the test sites, but we need a simple method of reprogramming the modules. We effectively have the six pin BDM connector available. Can anyone recommend hardware and software to provide an economical method of downloading new code to the modules in the field? We'll have modules at four or five different sites and I'm not about to send a laptop with CodeWorrier to every site!! All recommendations appreciated, Pat |

Pat: We here at P&E have both hardware and software available that may suit your needs. Our hardware interface (from PC parallel port to BDM connector) that you would need is either the Cable12, or the BDM Multilink. The BDM Multilink is our "souped up" cable12-- it works with targets with bus frequencies greater than 8 MHz, as well as low voltage targets. We will also have a USB version of our cable available in mid-May. The software you'd want to use for field reprogramming is cprog12z. This programmer is executable from a batch file, so field techs can erase, reprogram, etc with the click of a button. We have quantity pricing available if you have multiple field techs who would need to use the software. If you have any questions, you can e-mail me off-list or visit our website, http://www.pemicro.com.

Well, if all you have is the BDM, then you are pretty much stuck with at least some little BDM interface module (aka P&E or similar). We just finished up a project using the D60A and we just stuck a boot loader into one of the protected sectors of Flash. That allows them to load over a simple serial port, from a Visual Basic program that runs on any normal host PC under Windows. Seems very reliable, and needs no hardware (other than the serial cable). Sure not happy with some design features of the D60A bank switching and mode selection, nor with our P&E debugger not working if we do, but we got around them. jmk ----------- James M.

We'll have Cost effective BDM adapters are Elektronikladen ComPOD12 with StarProg software or Kevin Ross'BDM12 but the latter doesn't seem to support modern HC12/S12 derivatives. They use serial communication to the host and therefore have little risk that they won't work with your laptops. Look at the list archives about parallel port problems (especially with laptops). Like James M. Knox I wouldn't use BDM for firmware upgrade but serial communications. A good bootloader understands Motorola Hex or Fastload and doesn't even need handshake or delay times. Simply use _any_ terminal program and send the data to your uC. You only need some level translator and/or detection of "bootload mode" if the SCI is used for other communication.

I'm planning to adapt and use the serial boot see AN2153. I have a
push button on my draft circuit to initiate the bootloader. In another (PowerPC) project I have the software update is initiated when the application is otherwise idle and a unique sequence of characters received on the serial port this sets a non-volatile update flag. The project is spilt in to two parts bootloader and application. At power on the bootstrap starts and updates the application if the flag is set or start the application normally. There is a bit more to the story but that is basically it. Andrew Lohmann AIIE Design Engineer Bellingham + Stanley Ltd. Longfield Road, Tunbridge Wells, Kent, TN2 3EY, England.

Does it work with 24Mhz targets? I can not use your debugger if my target
runs at 24Mhz. B.K. Bob Kohan Life Fitness 10601 W.
