[U-Boot] Data transfer through Ethernet in u-boot.

[U-Boot] Data transfer through Ethernet in u-boot.

[prathika]

Hi all,
I am porting u-boot on PPC440 EP. I am porting a stand alone application 
on it.
I have coded for testing the peripherals of PPC. I  have no issues in 
executing this application.
Similarly I want to test ethernet communication also. I would like to 
transmit a text file from my board to PC and vice-versa.
Are there any example application for this in u-boot.
Please help me in this regard.

Thanks & Regards,
Prathika R

You should have coded the test code in the contexzt of  the  existing
POST  framework  instead  of  a separate standalone application. that
would have been more useful, at least to others.

Why the restriction on a text file? Why no arbitrary binary data?

See the "tftp" or "nfs" commands.

hi,
You have mentioned to add the test code to the existing POST framework. In my hardware, I have CAN controller interfaced to SPI interface, SPI DACs, parallel ADCs, 1553B controller interfaced to EBC.
I have  a CPLD to generate chip selects to these ICs.
If this test code will be useful, please let me to know how to add it to the POST framework.

I just gave an example of text file, it can be binary file transfer also between my board and PC.

I understood that "tftp" command in u-boot has been coded only for receiving data from the PC and not to transmit, to PC.If this is the case should i add the transmit code to the "tftp" command?
Even if I use this command for data transfer, what are the requirements for the application in PC side?

Thanks & Regards,
Prathika R

Well, study the existing code and the documentation, than add your
test code.

Yes.

I don't understand this question?

        --Here, I will be connecting my board through a GUI to a Windows
        PC. I will interact using this GUI. Actually if I use "tftp"
        command for file transfer, do I need some tftp client or server
        running on my Windows PC?

Yes, you need a tftp server on your PC.
