FNET for K60

[romano_r1]

Hi.

I will have to take a decision about selection the microcontroller. I must choice between MCF52259 and K60. Very helpful for me will be the answer for the following question: 

- What is the estimated date when the FNET for K60 will appear?

Hi Nikhil,

You can use S-record file, CW  CodeWarrior binary file (bin) or Raw binary file (raw).

By default, all types are enabled. It is controlled  by "type" parameter of the boot-loader.

Hi Andrey,

it seems you are the author of FNet. On my custom K60N512 board, FNet 2.6.3 bootloader and my application can both be launched successfully with application image type S-Record. I would like to use "raw" image type, and my build tool is IAR which produces output file myApp.out. I set the image type to raw, set the raw to some value, tftp myApp.out to the flash, but myApp cannot be launched successfully, sometimes it showed the message "There is no code on user application startup vector." My questions here are:

1. Can myApp.out be used directly as FNet raw type image? Is any file format conversion necessary?

2. What are the correct steps to download raw type image to flash?

3. What value of the parameter "raw" should be set?

Hi Logan Cheng,

>What value of the parameter "raw" should be set?

This is the address where you want to write a raw data.

But I guess that you may not use IAR .out file as the FNET raw format. The IAR .out format is not supported.

You can create your parser for IAR .out file (contribution is welcome.) or use S-record file which is the recommended format and supported by all compilers.

Best regards,

Hi Andrey,

Is there any difference between .bin file of CW and .sim file of IAR or any of them can work?

Thanks and regards

Hi Andrey,

I tried to use binary file generated in IAR and the FNET bootloader gives following error

TFTP downloading 'image.bin' (bin) from 192.168.204.107 :  |

Writing 504 bytes to 0x2000fef0 failed!

TFTP Error: Code 512 "ðþ".

following are the steps i follow:

1. I change the output format from motorola to binary in output converter option in IAR to generate the .bin binary file

2. I put the image.bin file into the root folder of tftp server then

2. set image 'image.bin'

3. set type bin

4. tftp

Is there anything wrong in the steps i follow?

I am suspecting the bin file generated by IAR is not the same as bin file from CW, but since I do not have CW cannot confirm it.

Any ideas?

Nikhil

[butok]

Most probably these formats are different (IAR and CW).

You should create own file-handler and add it to the TFTP boot-loader (use existing handlers as a reference).

[nikhilsarnaik]

I thought that might be the case

Anyways thanks for the info

Hi,

I've been tyying to get FNET working on my TWR-K60F120M board by following Adding an Ethernet Bootloader to Freescale MQX™ How-To Guide V1.4

and have some difficuilites on getting tftp working. Below is the error from the HperTerminal. I have the TFTP flags( FNET_CFG_TFTP_CLN and FNET_CFG_TFTP_SRV) turned on in fnet_user_config.h. My compiler is CW 10.4. I am new to the whole environment, any suggestion/help would be really appreciated.  Julie

The AN is very old - some settings can be obsolete or renamed.

So just use configuration parameters from current FNET release: \fnet\fnet_demos\<cpu>\boot\<compiler>\sources\xxx_user_config.h

Andrey,

Thank you for pointing me to the right direction. I found that the UDP flag was set to 0. After I got the tftp running, now I have a new  problem "default_isr entered on vector 3".  Do you have any suggestion for that?  Thank you.

On TWR-K60N512 it works => not reproduced.

There is no  official  port to TWR-K60F120M,  so not able to run FNET on it.

So you should step in a  bugger to the problematic place and find a source of problem.

Andrey, can I download FNET 2.5 from freescale? The zoom downloader on sourceforge is blocked by corporate policy and I can't get the direct download links to bypass it.

[butok]

Hi Oliver,

FNET is not supported by Freescale, even it is not allowed to put link to the FNET home page.

It is developed and supported by personal initiative (let say "FNET community").

So you do not have any chance to download it from Freescale web-site.

The only source is fnet.sf.net.

Best regards,

Andrey Butok

[OliverSedlacek]

Andrey, I downloaded FNET from http://cache.freescale.com/files/microcontrollers/doc/app_note/AN4367SW.zip?fsrch=1&sr=1 . I don't know why the corporate Mordacs block the sourceforge FNET download page, but I'll try getting the latest version downloaded.

Hi Oliver,

This version is very old one - do not use it (it is funny, all FNET names were deleted from the AN).

I have put it to my DropBox for you. Take it here:
