Flash programmer for MPC8548

Hi all,
   I'm using a EP8548A board with the MPC8548E processor. I have a problem when I try to use the Flash Programmer (CodeWarrior 8.7) and my Ethernet PowerTAP. Using the default configuration file for MPC8548CDS_sram_flash.cfg I can erase and verify the flash (AMD am29lv641d) sectors but I cannot program them.

I think that I'm doing some errors in the configuration or I'm not using the correct configuration file, does anyone have any suggestions on how to program the flash with this kind of board?

Thank you,
Paolo

Hi Paolo,

from the flash programmer UI:
1- press the load settings button.
2- pick 8548_CDS_sram_FlashBank#0.xml in the 85xx folder.
3- make sure the right connection, config file are selected
4- check the right flash device is selected in the next page.
5- than erase and blank check

Now create a dummy project from CW stationery wizard for 8548CDS
1- change build target from DEBUG to ROM
2- build the application

from 4th page of flash programmer:
1- select the binary you've just created with CW
2- set the format to binary/row
3- program
4- verify

does that help?

Best Regards

Thank you for your suggestion.

The problem is that I have already build a binary image with an external tool-chain (I mean, I have a u-boot.bin binary) and I need to place it in flash at the location 0xFFF80000 but with the Ethernet PowerTAP and the Flash Programmer (CW 8.7) I'm not able (until now, I hope :smileyhappy: ) to program these flash sectors.

With standard Embedded Planet 8548 boards I can write the flash using the u-boot already provided by EP (boards are shipped with a pre-installed u-boot), but this particular board has blank flash.

Paolo,

understood, the aim of the dummy project was to make sure the flash program was fine. The flash programmer refusing to flash may be due a ill formed .bin file.

I the suggestion does not do the trick than please log a bug at
