Cross Compiling for Linux C6x

A1) You can build the project either through command terminal or CCS, both method uses "cl6x".

A2) I think, yes you can like that.

A3) Refer to the c6x linux source code.

Hi Titusrathinaraj

thanks for fast reply

i think cl6x is C6000 Code Generation Tools (CGT) and output is ELF file (can't use for linux). is it correct?

in CCS i can create : CCS project (use CGT) , GCC cross compile project (use c6x-uclinux-gcc) and Makefile project with existing code what is your mean about "build the project through CCs" ?

can explain more or introduce reference?

Hi,

i think cl6x is C6000 Code Generation Tools (CGT) and output is ELF file (can't use for linux). is it correct?

cl6x is CGT and can be built in elf or coff type of output file, it can be used on Linux through elf loader (cl6x linux need elf loader stuff, I'm not sure it has or not)

in CCS i can create : CCS project (use CGT) , GCC cross compile project (use c6x-uclinux-gcc) and Makefile project with existing code what is your mean about "build the project through CCs" ?

What type of project are you building ?
You can use the same procedure which you have followed for hell world application.

Build your project either through command terminal (gmake) or CCS then use "c6x-uclinux-gcc" to make executable to be run on cl6x linux machine.

i compile hello world with command line and without any makefile
> c6x-uclinux-gcc -o hello hello.c
i try use CGT for compile and c6x-uclinux-gcc for linking but i didn't success
(please introduce reference if possible)
i decide on this step work on command line and use makefile

thanks for following

Hi Rex
Sorry for replaying late , I was out of office

thanks for your useful Post

i try run simple project using PDK function and library , for linux c6x (by makefile and c6x-uclinux-gcc on Ubuntu 10.04 host)

i have some problem and questions

Q1:i need to use PDK (.lib) library and i read that .a library should be used in Linux

when my makefile is this:

...

all: LED_play.out

LED_play.out: LED_play.o

LED_play.out: LED_play.o
	 c6x-uclinux-gcc $(INC) -o LED_play.out LED_play.o -L/opt/ti/pdk_C6678_1_1_2_5/packages/ti/platform/evmc6678l/platform_lib/lib/debug/ti.platform.evm6678l.lite.lib
LED_play.o : LED_play.c 
c6x-uclinux-gcc $(INC) -c LED_play.c

...

my result of make command is:

LED_play.o: In function `main':
LED_play.c:(.text+0x240): undefined reference to `platform_init'
LED_play.c:(.text+0x250): undefined reference to `platform_uart_init'
LED_play.c:(.text+0x25c): undefined reference to `platform_uart_set_baudrate'
LED_play.c:(.text+0x268): undefined reference to `platform_get_info'
LED_play.c:(.text+0x298): undefined reference to `platform_uart_write'
LED_play.c:(.text+0x2e4): undefined reference to `platform_led'
LED_play.c:(.text+0x2ec): undefined reference to `platform_delay'
LED_play.c:(.text+0x300): undefined reference to `platform_led'
collect2: ld returned 1 exit status
make: *** [LED_play.out] Error 1

after rename ti.platform.evm6678l.lite.lib to libtest.a and change makefile to this:

LED_play.out: LED_play.o
	 c6x-uclinux-gcc $(INC) -o LED_play.out LED_play.o -L/opt/ti/pdk_C6678_1_1_2_5/packages/ti/platform/evmc6678l/platform_lib/lib/debug -ltest

, my result of make command is:

7144.output.txt

how can i use PDK library? Rebuild library is correct way?

 thanks

Ebi

update:
pdk library generate with CGT for use in CCS and i decide to rebuild PDK with c6x-uclinux-gcc .
i try to use CCS but can't change compiler from CGT to gcc!
rewrite makefile to build library from source is correct solution ?
anybody can help me?

thanks...

thanks Rex for your reply!

i need to PDK library and try to Rebuild it with c6x-uclinux-gcc

i continue my work in this post
