CFFlasher + M54451EVB

IRTrans — Wed, 10 Aug 2011 09:54:57 GMT

Hi all,

I have got a M54451EVB board. I have compiled a new kernel and other stuff I would like to install.

Furthermore I need to reinstall u-boot.

I have compiled all the images - however I am not able to flash them because I could nowhere find a CFFlasher version that supports the M54451EVB.

The manual says

"Make sure you are running the most recent version of CFFlasher with support for the M54451EVB Revision D"

However - no idea where to get it. I already tried to modify the .cfg files - however that is quite complicated as a lot of different registers need to be set on init.

Does anybody know where to get the .cfg file for the M54451EVB?

We had issues with this as well when we started, after submitting a service request, we found that the M54451evb does not support the cfflasher. Here is the message I got back:

Please create a brand new project for 54451EB and try to flash it again with CW Flash Programmer. A new project created with the New Project Wizard must contain all the necessary configurations to flash the board.

As I dont know which CW version you are using you can find attached 2 videos (one in CW7.2.2 and other in CW10.1) showing the process of flashing a new project into 54451EVB just in case you are missing any step.

You can find also attached an image showing the jumper configuration I have set in the board I am using.

The Chip Selects (CS) are configured in the .cfg file. If your problem persists please let me know which CW version you are using in order to see which is the correct cfg file configuration.

Hope this helps.

Have a nice day!"

This site is giving me some problems, so if you send me your email, I will email you the files (dmendelsohn@bullexsafety.com)

Ok, apparently the link attachment did work, here is the jumper configuration picture he talks about

Hi,

thank you for your answer.

However, as we are not using CW that does not help a lot.

I tried to install CW 7.2, however it does not install as all our development machines are x64 based. Unbelievable that they still sell SW that does not run on Windows x64 ...

Anyways, with the M5445x reference manual I was able to make my own cfg file for cfflasher.

Here it is - maybe it helps someone else:

DEVICE MCF5445x
RAMBAR1 80000000
FLASHBASE 00000000

INSTRAM RAMBAR1
DATARAM RAMBAR1
DATASIZE 0x2000

FLASHALG 28F128P33B(1x16)

.init

wcreg RAMBAR1 RAMBAR1 0x221

write.l 0xFC008000 0x00000000
write.l 0xFC008008 0x00101180
write.l 0xFC008004 0x00FF0001

With this config file I was able to programm using cfflasher.
