Linux/TMS320DM8147: TI 8147 NGINX compile

Hello
Thank you for answer

but on the page by your link its written 'Important Note
This EZSDK is Not Recommended for New Designs (NRND). Please use the more current RDK. EZSDK support and design services are available through members of the TI Design network. For more information, please contact your local TI Sales Representative.'

I have DVRRDK_03.00.01.03

but I still can't understand how to use it to cross compile the nginx :((
and the pdf file DM81xx_DVR_RDK_Install_Guide.pdf is very strange I am trying to follow the full build ınstruction but its not succeed as lost dependence

also I have a
8107-toolchains/cgt_a8/arago/linux-devkit
as writtent in readme file I tried to start it as

. ./environment-setup it looks like it runs enviroment
but when I try to ./configure at nginx its written

-----------------------------------------------
[linux-devkit]:/linux-devkit/ngx> ./configure --prefix=/opt/nginx
checking for OS
+ Linux 4.10.0-26-generic x86_64
checking for C compiler ... found but is not working
./configure: error: C compiler arm-arago-linux-gnueabi-gcc is not found

------------------------------------------------------
arm-arago-linux-gnueabi-gcc runing as well but in compiling its 'not working'

I trying to understand is that way for cross compilation is correct or I doing totally wrong

thank you

Thank you very much
I used EZSDK as you suggested and was needed to edit two more parameters in auto-build in nginx and was succeed
