IBL Query : Setting up dynamic ip address

Hi Vidya,

Welcome to the TI E2E forum. I hope you will find many good answers here and in the TI.com documents and in the TI Wiki Pages (for processor issues). Be sure to search those for helpful information and to browse for the questions others may have asked on similar topics (e2e.ti.com).

Please refer below wiki for IBL updates.

Also refer boot loader user guide for various boot modes supported and more information.

I hope this helps.

Thank you.

Hi,

Thanks for your reply.

I read your link, but couldn't find suitable answer.

can you please answer my query directly?

Hi Vidya,

Please refer to the discussion on the e2e thread provided below for suggestions:

http://e2e.ti.com/support/dsp/c6000_multi-core_dsps/f/639/p/361302/1270931.aspx

You can either re-enter the ROM from the application or re-enter the IBL by chnaging the DSP program counter to appropriate entry point in the IBL or the RBL.

Thanks for your reply,

I gone through the link.

We don't want to perform soft reset to get back to iBL since that would reinitialize our configuration again.

Our main criteria is to customize ibl to have tftp command prompt in loop. From prompt, we are trying to boot application and once application is success , it should return back to ibl command prompt to receive next command.


In function iblEthBoot,

 Application is booted with entry point address returned from iblBoot,

 if (entry != 0)  {
         iblStatus.exitAddress = 1;
         exit = (void (*)())entry;
        print_f("\n I am in exit addr %x ",exit);
        (*exit)();
    }

Entry address will not be visible in application , then how to return back to ibl. Please guide me on this.


Also please guide, whether its possible to dynamically assign ip address.such that i can boot the application from different server instead of using hard coded serverip in device.c.

Regards,

Vidya

Hi All,

Any inputs to solve this issue ?

Hi All,

Thanks for inputs. I solved the issue .Now, I am able to modify the ip  and assign to our c6678 structure and fetch it back.

Can any one help me in solving out my query1.

Query 1: We are able to boot the ibl and invoke application through tftp successfully.but once application is terminated,its not returning back to ibl. I have to once again switch off my board to run the application again. Plz guide me how to return back from application to ibl without doing soft reset.
