Hi folks, First let me say that I have read/am aware of Motorola's App Note 1828 on the subject. I was wondering if anyone had written their own software for programming the Flash of an HC12 over CAN. How well did it work? Did you employ the bootloader-to-load-a-b

I bulk erased the flash memory on my 68HCS12DP256, which shouldn't be a problem because I have a BDM POD, but now I cannot communicate with the target. I have tried all the options that Debug12 allows but with no sucess. When I reset the micro I think it is jumpping to Flash but I cannot tell. I am u

I'm writing some FLASH programming code, and now I have reached final step of securing the microcontroller. Unsecured microcontroller has lower bits of byte at 0xff0e equal to 0bxxxxxx10. Now if I want to secure it, I have to write something different there. Because LSB is already zeroed, there are two possibilities: one is to first erase it and then program

Hello I have some problems programming the internal flash arrays 02, 03 on a 912DG128A using P&E Prog12Z. As someone posted before, Prog12 will verify the contents as correct but ICD12 and NoICE shows only 0xff at these locations. Does anyone have some hel

Hi All, I am looking for a flash programmer for Motorola MC9S12DP256B with the following functions: It can load a firmware image (say S-Record) into MCU and overwrite the existing (crashed) firmware inside the MCU. We also have to keep some calibrat

Hi all, I've posted this to P&E's site, but am cross-posting here for any thoughts.

Hello! Im new to freescale processors and run into the problems while trying to flash software into it. So maybe you could help me. I designed one PWB with 912D60A on board. In order to flash it, I added BDM connector to it (+5V, GND, BDM, Reset), as was recommended by freescale. After receining that manufactured PWB, I started to find a algor

Hi Everyone: We are using the 9S12DG128a, and ICC12compiler and want to add USB for a flash drive. * Does anyone know of libraries either shareware or commercially (preferably available for the HC12, but just ANSI C would be fine) in C to implement a windows based file

Hello, I am using CW to develop and app using the HC12D60A MCU. I have settings in EEprom that I don't want overwritten when the debugger is started. I have the section declared as "NO_INIT" in my flash.prm file, but the EEprom still gets initialized to FF's on

I have some simple code which is runing fine through Cosmic's ZAP debugger. I believe that ZAP actually programs the onboard flash so I assumed that after it was programmed I would be able to power down, remove the BDM interface, power back up and the chip would run the code (def

Hi, With a self programmed bootloader which runs in Ram, we have some trouble to erase memory flash block with mass_erase command. But if we send two times the function, we have a correct erasing. Therefore, same function but in writing mode works properly after erasi

Hello All. I have recently started to upgrade an old board that uses DP256B's with DP512. I managed to program the board a couple of days ago with no issues. Today, I ran into a problem with my application code - it couldn't write to paged flash when downloading data from my PC app. This was quickly identified as a problem with the bank select in my flash loading routine. However no...

Hi all, I'm writing a program that needs to store a large amount (thousands?) of small chunks of data (maybe 32 bytes length) into flash (cpu 12DG256). No problems in read / write / erasure, but I found what I think is a weak point in the process. Sometimes, due writing of new data in previous
