Linux-c6x: TMDSEVM6678LE the first steps

I rebuild all components from source code. I setup all necessary tools and after edit ~/linux-c6x/linux-c6x-project/setenv file. After that I run make utility. In the setev file declared two variables:

export CGT_BIOS_DIR=~/ti/cgt_c6000_7_2_2
export CGT_LINUX_DIR=~/ti/cgt_c6000_7_2_2

Can you tell me, I set correct value or not for CGT_BIOS_DIR, CGT_LINUX_DIR?

Thank you.

Rex Chang, thank you for your reply.

I set all fileds in setenv file as you say. And get this output:

source setenv
embedded@kva:~/linux-c6x/linux-c6x-project$ ./prj config
scripts/setup

distro == Ubuntu
all following packages already installed: build-essential git-core expect automake zlib1g-dev bison flex mtd-utils fakeroot genisoimage
/bin/sh looks like bash
predefined GCC directory /home/embedded/linux-c6x/opt/gcc-c6x containing version 4.5-124
found uClibc source in /home/embedded/linux-c6x/opt/gcc-c6x-uclibc
using predefined CCS directory: /home/embedded/ti/ccsv5
using predefined TI CGT directory /home/embedded/ti/cgt_c6000_7_2_2 for Linux programs
using predefined TI CGT directory /home/embedded/ti/cgt_c6000_7_2_2 for BIOS programs
using predefined IPC directory: /home/embedded/ti/ipc_1_23_01_26
using predefined BIOS directory: /home/embedded/ti/bios_6_32_01_38
using predefined XDC directory: /home/embedded/ti/xdctools_3_22_01_21
setup is complete

And than I successfully rebuild all components: kernel, ibl, syslink, and rootfs. I try burn this images in EVM and posts here about results.

Thank you for your help.

Update:

IBL successfully burned in eeprom51 and started.

Thank you for your help.

Hello, I have a problem when I execute the instruction "./prj config", the problem is when I execute ,it stopped and print that the setenv has not been sourced ,how do I solve this problem, and  what is your mean that "enable the env variable in set env",and how I enable it ,thank you ！

Hello!

After the first time running ./prj config you must edit the setenv file. It is placed in the same directory as ./prj. Then you need type in command line: source setenv and press enter. In setenv file there are many environment variables for example: CCS_DIR. Directive "export" in the setenv file make this variable visible in the system. It is mean enable this env variable. May be it is help you.

Please follow the steps shown in Release Notes,

cd linux-c6x-project
 ./prj config
 [Please edit setenv to specify what to build, or leave it untouched to build the example configuration]
 ./prj config

The 2nd "./prj config"  will source setenv and build the images.

Hello , I followed the steps shown in realease notes ,and I run ./prj config sucessfully, then I executed the command "./prj build " , and some errors displayed ,and I don't know the reason ,can you help me .here is my setenv and the error:3441.setenv.txt

Hello!

1) I suppose, you need to edit setenv file and set the some variables. Here is example from my setenv-c6x:

export GCC_DIR=~/linux-c6x-git/opt/gcc-c6x
export CGT_BIOS_DIR=~/ti/cgt_6000_7_2_2
export CGT_LINUX_DIR=~/ti/cgt_6000_7_2_2
export CCS_DIR=~/ti/ccs_5_0_3/ccsv5
export BIOS_DIR=~/ti/bios_6_32_01_38
export XDC_DIR=~/ti/xdctools_3_22_01_21
export IPC_DIR=~/ti/ipc_1_23_01_26

2) After editing you need to run command: source setenv, and look at the output of ./prj config, if it is correct - run ./prj build.

Hello, after I follow your advice ,I meet another problem as follow:

and here is my setenv

I don't see anything wrong with your setenv file. Is the my-linux-c6x re-used from earlier build failure? Could you download the linux-c6x again and start a new directory and see if it happens. Follow step by step as described in Release Notes.If you still have problem, post the steps you did, the error file, such as the  libc/stdio/,fdopen.os.dep as mentioned in your post.
