Hi Meng,

But using build command with (make linux_install)  will lead to failure.

Where are the kernel installed to?

the error message show that the path "/home/kemeng/ti-processor-sdk-linux-edgeai-am62a-evm-10_00_00_08/targetNFS/boot" is not allow to access."

How is this targetNFS generated?

by using command" sudo setup.sh"

i using the default path during running the script of setup.sh.  is this process is uncorrect. please let me know

Are you working on an AM62A7 EVM or your custom board? What interface does the board boot from? That will determine where to install the kernel to, this is for my previous question.

yes. i am working on an AM62A7 EVM board. not my custom board. I need to set the Product start up from EMMC. So I choose the TFTP and NFS using as my Kernel image and Target file system.  

by the way . I download a image "tisdk-edgeai-image-am62a-evm.wic.xz" form TI official website "PROCESSOR-SDK-LINUX-AM62A Software development kit (SDK) | TI.com" . and right now using SD card with this image to startup the system. 

Right now i need to update the boot and other bin file to this board though the eth0 or Serial. To verify the SDK env. and adjust the code to the CMOS and Serdes to check the system status.  and I did not seem there have a build script can build all file and assemble all bin together. This is different from my pervious project. 

Hi Meng,

Thanks for the details. But it seems you mentioned 3 different things.

If you have any issue in using SD card boot on the EVM, please create a new E2E thread and provide the details of the queries.

I am not sure if you still need help on TFTP/NFS boot since you use SD card boot now. If so, please clarify and we will continue communicate for this matter on this thread.

It sounds like you are trying to compile a Linux user space program? If so and need help, please create a new E2E thread and provide the details of the queries.

Hello Liu. i using the sd card card boot now. i need to flash the software target file insideof the image file from  Ti webside. So please help to deal with this problem first. thx. 
and for your option. I need to change the kernal to SD card. I will run the setup.sh script again to adjust the config.

bu the way for emmc setup. i will reopen a ticket to ask question. thx

You don't need to do this, if you only want to transfer the software binaries to the Linux running on the EVM. You can connect the EVM ethernet port to the network with the PC, setup IP address, then using command such as scp to transfer the files to the Linux running on the EVM.

unfortunaty. the eho seems not work in my system.  
when derictly connect the EVM board and PC. 

Using serial minicom can have access the SOC. and check the ipconfig. It do not have ip like "192.168.x.x" appear. 
after a have addr add 196.168.x.x  dev eto
I can see the ip addr. but i can not ping with this ip by using my PC.putty is not working either

When connect the EVM with the PC via Ethernet, you either have to have the DHCP server running on the PC to provide an IP address to the EVM, or manually set the IP address on the EVM to be on the same subnet with the IP address on the PC.

For details, please check the instruction linked below.

For transfer files to the Linux on the EVM through Ethernet, please see the example linked below.

https://dev.ti.com/tirex/explore/node?node=A__AYfms9.5mHI3xFT3MVWaoQ__AM62A-ACADEMY__WeZ9SsL__LATEST

in Linux the PC can not link with SOC. ping 192.168.101.2 show do not have message tranfer

What is the IP address on your PC?

here is the log i using ifconfig in my linux PC. the PC using the wirefire link to the public network

The log show that the physic link for SOC and PC is correct. I choose both window PC andLINUX PC. They all can not ping with the am62a board.

Did the soc need to config the access for eth0 visit? Or is the switch in the board setting is incorrect?

Or maybe the Image i flash into the SD card do not support eth0 setting?
 

You configured the EVM IP address to be 192.168.101.2/24, but the PC IP address doesn't have one on the 192.168.101.0/24 network. Of cause the ping will fail.

Is the problem come from the PC. I have switch different PC to visit the board.

PC network can visit international . Can not visti SOC board.  how should i do to solve the problem? thanks very much

For nodes on a network to communicate to each other, their IP addresses should be all on the same subnet.

Depending on how you connected the EVM with the PC (with or without a network switch in the middle), you need to ensure both IP addresses are on the same subnet.
