I have been using an old Atmel 8535 chip - ABC miniBoard for a while now and I thought it might be time to move up. I am looking into developing systems with HCS12 and would like to be able to program a 9S12DP256 via RS232 comms or parallel port from the PC without the need for purchasing a module to do the programming. ie I would like the ISP/BDM to be on the controller board itself. If I am right the AN2153 application note describes a method for programming the HCS12 via comms without the need for an external module. Does anyone know a way to program the HCS12 initially via comms without an external BDM module? Does anyone have a circuit/code/PC program lying around that I can use to program the HCS12? Maybe someone has circuits/firmware for a homemade bootloader. Hints also appreciated! :D |

Hi, I would suggest you download Debug12 version 4 as this has the bootloader s19 file. However you will have to program the chip via a BDM of some form. I stock the Elektronikladen Motorola range of products in Australia, http://www.elektronikladen.de/en_index.html you could use a compod12 to do it. Or if you have some hardware, I could program it for you. (I'm near Melbourne.) Hope that helps. Peter L.

What programs can be used to program the HCS12 once i have Debug12 programmed? Also, where can I download Debug12 version 4? how much is your BDM?

I just realised i already have debug12 from motorola website :P --- In , "tech_e_micro" <balbr001@i...> wrote: > What programs can be used to program the HCS12 once i have Debug12 > programmed? > > Also, where can I download Debug12 version 4? how much is your BDM?

Some of the new HCS12 mask sets arrive with a bootloader already programmed into a portion of the device FLASH. This allows loading your own application code through SCI (RS232) or CAN, and program it in the internal FLASH and EEPROM. I don't know many details, but I know this exists. It is intended for a cheap production solution (to program the Flash and EEPROM during production using SCI or CAN). Hope this helps, Doron Nohau Corporation HC12 In-Circuit Emulators www.nohau.com/emul12pc.html At 10:54 27/06/2004 +0000, you wrote: >I have been using an old Atmel 8535 chip - ABC miniBoard for a while >now and I thought it might be time to move up.

I have found out that the D-Bug12 software/firmware, once loaded onto a board, such as the GP256 T board can be used as a programmer(BDM pod), for anyone that was curious about this. You can get all the information on the motorola website, you will need a motorola login to get access to the dbub12 s19 files tho, the circuit for using it as a pod can be found in the T board schematic. --- In , "tech_e_micro" <balbr001@i...> wrote: > I have been using an old Atmel 8535 chip - ABC miniBoard for a while > now and I thought it might be time to move up.
