Problems of running the OOB demo？

Hi all，

I am a newer and I have a EVMK2H Rev.3 on my hand now. But when I was getting start and trying to run OOBdemo, problems happend.

1.when burning nand, the process stop in "start loading nand.bin". Otherwise, I had burnt nand before and i donot know if it matters.

2.This is the boot log，but always in fail. I just cannot understand why my tftp serverip is 0.0.0.0?

.

3.In the guide, I met this message about programing EVM. But I just wander is it mean that burning nand.bin file is not necessary to rev.3 ?

And it is my pleasure if someone would give me a response. Thank you!

Regards.

Feiyue.

    Feiyue,

    For the Rev 3 EVM, there is a different process you need to follow to program your NAND. See here: http://processors.wiki.ti.com/index.php/Program_EVM_UG#For_EVMK2H. You'll need to set up a TFTP server to do this.

    Additionally in U-boot, you need to configure your environment variables before you boot. The user guide covers some of these variables: http://processors.wiki.ti.com/index.php/MCSDK_UG_Chapter_Tools. Specifically, you'll need to configure at least serverip and tftp_root variables.

    Hi Dharik，Thanks a lot for your suggestions. I followed the steps but got into trouble in U-boot. I use the win7 host so I am not sure if the U-Boot bin file is the file located in <mcsdk_linux_3_00_04_18>, but it is the only one. I loaded the bin file in to chip memory with CCS and  the EVM worked with "No Boot/JTAG DSP Little Endian Boot mode". I went through above steps, but I do not known how to get a U-Boot prompt in the end like this demonstrated in http://processors.wiki.ti.com/index.php/MCSDK_UG_Chapter_Tools. Does not it need to change the boot mode switch SW1 in the process? Does not U-boot run in the SPI Little Endian Boot mode? 

    Otherwise, I really want to know if the U-boot and programming NAND are  the necessary procedure to use the EVM. I just want to make the evm be a controller (e.g. PID or MPC)in the beginning. The controller would receive data from  upper layer through Ethernet, then process data in dsp and transfer the results to the lower layer using UART. This seemed be very simple, but I not sure how to use the evm efficiently.  Would you mind giving me any recommendations about this? Thanks again. 

    regards.
