Flashx device problem on MQX 3.5 and MCF52259

sav · ‎02-18-2010

Hi,

We have updated from MQX 3.4 to MQX 3.5 and got a problem - FlashX device doesn't work.

We used M52259DEMO board and example from "...\Freescale MQX 3.5\mqx\examples\flashx" with Code Warrior 7.2.

On MQX 3.4 (Code Warrior 7.1.2) everything was fine (my code and the example).

Here the example output:

MQX Flash Test Program
Beginning read/write tests
Flash device flashx: opened
Flash Device Identity: 0x00000013, 0x00000004, 0x0000006d
The BASE_ADDRESS: 0x13000
Number of sectors: 4
The WIDTH: 32
There are 4 sectors in Block 1
Block 1 Sector Size: 4096 (0x1000)
Total size of the Flash device is: 16384 (0x4000)
Erasing entire chip (this will take a while)
FLASH_IOCTL_ERASE_CHIP failed.

And here my "user_config.h":

Can everyone help me?

Thanks

Hi,

It is a bug in MQX 3.5. and it will be fixed in next release.

You can fix it by followed steps:

1. open the file [your_MQX_installation]\src\mqx\source\io\flashx\freescale\flash_mcf52xx.c

2. find the mcf52xx_ram_function function

3. remove #if 0 and #endif lines

Hi,

Thanks a lot!

Problem was fixed by your steps.

Dam, I wish I had seen this a day earlier!

Is there a developers email list so we be notified when MQX issues are found? New release's released etc?

Also, I updated my applicaiton as above and everything works, however, the MQX3.5 flashx example always returns null when doing fopen("flashx:", NULL);

Hi,

I adjusted the code as suggested, removing the #if and #endif, however, my flash card is not recognized.

"Unable to open flash device flashx"

User config is the same as shown further up. Any more suggestions? I tried two different CF cards.

Best Regards,

Elmar

OK. I have to add that I forgot to recompile the whole library using build_libs.mcp after making changes to the user_config.h. This solves at lest the compact flash card recognition.

However the application terminates after doing some operations so that I cannot put it to use. This is what hyperterminal produces:

Is this built into the project?

CarlFST60L · ‎03-11-2010

That is the normal output of the project.

I still have this strange problem where the MQX3.5 flashx example will not open the flashx driver even after a full rebuild, however, it works fine in my application... I have no real need to track down the cause of this as the driver works fine in my application, but I guess it must be something in the project settings somewhere...
