Questions about ethernet boot on evm6670

user4094083

I want to boot my own project via ethernet on evm6670.

First,I have booted small projects via ethernet,including single-core and multi-core.I referred the example in MCSDK(hex6x,bconvert64x,bootpacket,pscendpkt).I used JTAG to connect PC and then used CCS to see it results and it succeeded.

But,when i am booting my own project,after using pscendpkt to send packets,i want to connect the target to see whether it succeeded or not.Then CCS shows error when i want to connect my evm after booting via ethernet,it says"cpu hangs out................."

My own project is large(3,000kb .out).Is it to large?or some other questions?

Which memory are you using for your own application ie where your code reside ?
Is that from MSMCRAM or DDR3 ?

Hi,

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).

From my understanding, it may not be the issue with size of your project and it depends on your own project. I would recommend you to debug by enabling debug messages using serial port on your own project.

1. Have you verified your project before loading and running from ethernet using debug boot mode using emulators? What does your application do?

Thank you.

Thanks for answering.I have searched my question in this forum but never found a solution.
the memory I have used is DDR3、LL2 and MSMCRAM.

My application is to process physical layer data of LTE protocal.The application is correct and has been verified in emulators.But when booting via ethernet,it failed.

Hi,

Hi,
Please find the DDR init code in platform project(DDR3Init),
Refer platform_init() on \ti\pdk_C6670_x_x_x_x\packages\ti\platform\evmc6670l\platform_lib\src\platform.c file.

You can integrate this on your target application. Thank you.

Hi,

Better to use TFTP boot for your requirement. Please take a look at below documents for TFTP booot.

MCSDK Path: "\ti\mcsdk_2_01_02_06\tools\boot_loader\examples\i2c\tftp\docs\README.txt"

Thanks,

I have integrated DDR init on my application but it still doesn't work.PC pointer is in the wrong place.

I wonder if i succeed to initialized DDR3 or i have failed.Is there any way?

Thank you!

Hi,

You can add DDR3 memory read and write code on your test application, after initialize DDR3 memory. It will success the DDR3 initialization fine.

Thanks,

Hi,

I have some more questions.According to bootloader data sheet,"The PHY is not initialized by the RBL and it is the responsibility of the host to initialize the ethernet PHY."

What is "PHY" and "host" refer to?

thank you.
