Hi Jim,

i think yes.

Hi Jim,

If you have the latest beta board, then you can do direct ethernet boot. The FPGA in the evm automatically boot in I2C irrespective of the boot mode set and does the PLL fix and then re-enters in ethernet  boot. So you don't ned to do anything except not touching the EEPROM memory as they have the IBL.

thanks,

First thank you for the answers.

Arun,

If I understand you correctly on the EVM the FPGA first causes to I2C boot, not metter what the pin setup of SW3 [2:4]? (thats why I see I2C boot in the DEVSTAT register?)

When I will use our own board (Not the EVM), need I do the same in order to do the PLL fix? (Means we need a EEPROM memory with IBL?)

Thanks,

Jim

For custom boards, you can use the lite simple PLL fix and reenter in desire boot mode. The fix can be found in the ti external link

Thanks,

Thank you for the info.

Do you have an example of direct etherntet boot on the EVM (without the IBL)?

Thanks,

Jim

Hi Jim,

I don't understand what you mean. The link that i have given above will not use IBL. Please let me know if you need something different.

Thanks,

Arun.

Hi Arun,

Sorry I noticed it only after I replied.

Anyhow I have some problems compiling it using the Build.bat file (The final step in the readme file). Do you have it as a ccs project?

One last thing, is there an example for a PC application allowing to load the code via Ethernet?

Thanks,

Jim

Hi Arun, Jim,

As per Jim's questions:

Is there a ccs project for the boot fix?

Is there an example for a PC application allowing to load the code via Ethernet?

many thanks
