Hi Andrey

More details about the "TFTP Bootloader" would be great. :smileyhappy: Is this functional with the MCF51CN ? What are the use cases? Dumb question: can I upload a new s19 file from a remote location? Erases the whole internal memory? Do I have to use a special CW template? What is the memory footprint? Do I have to use an external memory to retain the temporary information or store information as it get it? Is there some kind of limitation?

Thanks!

Hi Paolo,

>>More details about the "TFTP Bootloader" would be great

You may get the additional information about the Bootloader in FNET User Manual or here:

http://fnet.sourceforge.net/manual/quick_start_boot.html

and here:

http://fnet.sourceforge.net/manual/how_to_add_boot.html

>>Is this functional with the MCF51CN ?

Yes. It was developed for all FNET supported MCUs (Lasko, Kirin2/3 and Reindeer)

>>Dumb question: can I upload a new s19 file from a remote location?

Yes. The Bootloader supports S-record, CW bin and raw-binary file images.

>>Erases the whole internal memory?

Yes. Except reserved blocks (FNET Bootloader code and a block reserved for parameters storage).

>>Do I have to use an external memory to retain the temporary

>> information or store information as it get it?

No. The Bootloader writes directly to on-chip flash (no external memory needed).

Hope it helps,

Andrey Butok

Hi Andrey I wanna move a servo-motor via ethernet and I just download the Fnet 0.6.3 but looking in the demo code the size of the code is bigger than my licence code size, and I dont need all the features that Fnet provides me, can you help me with a little example of a basic http request or just a ping with the target.

Thanks a lot!

Re: FNET - TCP/IP Stack

butok — Fri, 11 Dec 2009 16:12:13 GMT

Hi NeuroSolutions,

I suggest you to buy normal CW license.

You can try to add the FNET to your project http://fnet.sourceforge.net/manual/how_to_add_fnet.html and/or play with configuration parameters http://fnet.sourceforge.net/manual/group__fnet__config.html , after FNET initialization you should be able to ping the board. If it does not help you should obtain normal compiler license.

Re: FNET - TCP/IP Stack

NeuroSolutions — Fri, 11 Dec 2009 21:41:23 GMT

Ok, it will be the ideal but its a little project for the research group in the University and I dont have the money to buy it. The idea its only to send via ethernet a command that indicates the number of degrees that a servomotor has to move. If you can help me with a little code that do that, send a variable from a pc to the micro, I would be very grateful... I dont need the telnet module, or ftp... I know that it will be a lot of modules that I can be deleted.

Have you considered uIP tcp/ip stack for v1 architecture? xMAP indicates is around 32KB including a web page which will fit with your 64KB limited CW license.

I will try to get details about gcc open source tools if this is available for v1 architecture

Demo is here:

http://www.freertos.org/index.html?http://www.freertos.org/a00090.html#FREESCALE

Anyway find attached example code

Does this help?

Re: FNET - TCP/IP Stack

NeuroSolutions — Sat, 12 Dec 2009 03:04:07 GMT

Yes it helps a lot, I'm going to explore FreeRTOS and any question I get i'll be probably asking here. Thanks!

Re: FNET - TCP/IP Stack

PaoloRenzo — Sat, 12 Dec 2009 03:16:57 GMT

I got some info regarding GNU tools

http://www.codesourcery.com/sgpp/lite/coldfire

More info:

http://www.towergeeks.org/forum/topics/alternatives-to-codewarrior?id=3370525%3ATopic%3A1156&page=2#comments

I'll do my best to explore these free solutions, but right now I'm not familiar with them

In the meantime, uIP will work for you

Have fun

Re: FNET - TCP/IP Stack

EugeneLeigh — Fri, 05 Feb 2010 20:10:41 GMT

Did you have any luck using FreeRTOS + uIP on mcf51cn ?

It works for me too and I would rather use GNU tools from codesourcery but don't have much time to fiddle with it at the moment.

Eugene

- Freescale CodeWarrior for Microcontrollers Version 6.3.

Hi Satinder

I can't help with FNET but there is a complete, fully documented and proven MODBUS serial/TCP module for the M522XX available at http://www.utasker.com/modbus.html

How to add HTTP Firmware Server to the FNET Bootloader?

Is there any example about that?

Thanks.

Re: FNET version 0.7.0 release

butok — Mon, 29 Mar 2010 18:15:11 GMT

Hi,

Look at the “shell” demo application.

Main difference is in the configuration files (do merge):

fnet_user_config.h

fapp_user_config.h

Best regards,

Andrey Butok

Hello Butok,

My idea is to create an application for update coldfire firmware from embedded web server (FNET Web Server), using post method of htlm form to transmit the firmware update and then self-programming (FNET Bootloader).

The HTML example code could be:

<html><head> <title>Update my MCF52259 Firmware </title></head>
<body>

</FORM>
</body>
</html>

possible to do this with FNET ( FNET HTTP BOOTLOADER )?

Thank you very much.

Re: FNET version 0.7.0 release

butok — Tue, 30 Mar 2010 14:57:43 GMT

Good idea.

But current version of the HTTP server does not have support of the POST request.

You should implement it by yourself.

Best regards,

Andrey Butok

mjbcswitzerland — Tue, 30 Mar 2010 19:36:51 GMT

Note that the uTasker project for single chip V2 parts includes HTTP POST support for passing parameters or files. It also includes HTTP POST upload support (optionally encrypted); this can be used as a dedicated boot loader, occupying about 25k of FLASH (that is a boot loader including web server and a dedicated upload page) or as a 'bare-minimum' boot loader occupying 2k or 4k of FLASH - in this case it uses intermediate storage in either internal FLASH or external SPI FLASH to receive the code and then installs the new application in a manner that can't be distrupted, even due to power failure etc. during the process.
