Part Number: EVMK2H
Tool/software: TI C/C++ Compiler
i have been working with the K1 C6678 evm and we have managed to get it up and running with ethernet boot
we would like to do the same with K2H, we are only using the DSP cores, ARM cores are not required and the question is:
1. Is it possible to boot the K2H exactly the same way we booted the C6678 ? is it possible to not touch the ARM cores at all ?
2. If the answer is yes, i would like to know how to configure the K2H to behave exactly like the c6678 so that our boot process that worked for the c6678 would work here as well
3. if the answer is no, can anyone point me to the right guids and materials for Ethernet bootloading on the K2H?
I looked at:
I didn't find the Ethernet boot information, only thing there is SPI NOR boot. I thought ARM core is the boot master and I asked boot expert for Ethernet boot help.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

In reply to lding:
thanks you so much for response,
i would appreciate it if we could get an answer today, we are a little short on time
In reply to jameel magzal:
Please check the datasheet and bootloader user's guide. Search for "Bootloader" in datasheet.
In reply to dzhou:
I checked the datahseet, it always references 2 user guides:
1. DSP bootloader for keystone architecture user's guide
2. KeyStone II Architecture ARM Bootloader User's Guide
none explain how to directly use the DSP cores to boot on keystone II
what i need is "DSP Booltloader for keystone II architecture" if there is anything like that.
i just want to know if it is possible to bypass the ARM cores and simply use K2H as if i am using the C6678.
Please take a look at
Section 10.1.2: you will need to use "PublicROMBootwhenthe C66xCorePac0is the bootmaster" mode.
You can't completely bypass ARM cores because ARM core is determining whether DSP is the boot master or not, but after that decision and if you configure DSP to be boot master, then it will be similar to what you have accomplished with C6678.
thanks for the reply, there is one thing that is bothering me in this, the K2H evm that i have has only 4 pins for the boot configuration, and they only correspond to the first 4 bits of the devstat register, and in this case i can't set up bit 8 to have the DSP as master boot.
any idea how to go around this ?
Please take a look at this link about how to use a bootmode that is not supported by the DIP switch combinations.
