Build fail eclipse FreeRTOS I.MX7 Cortex-M4

JesusP88 · April 6, 2019, 5:49pm

Hi members!
I have a problem in Eclipse, I’m using Ubuntu 16.04 for compile FreeRTOS, followed this post Tutorial1 and Tutorial 2.

I work with the next files:

gcc-arm-none-eabi-4_9-2015q3 gcc-arm

and Toradex FreeRTOS

git clone -b colibri-imx7-m4-freertos-v8 git://git.toradex.com/freertos-toradex.git freertos-colibri-imx7/

but when I try to compile the Eclipse (Eclipse neon .3) show the following error:

error This port can only be used when the project options are configured to enable hardware floating point support.

This is the make output:

Please any suggestion about it? because I google it but I do not have lucky.

hi @JesusP88

Did the example using command line compile for you?

Yes, this is the output:

Could you share with me a make file for compile freertos? Maybe if I use a import makefile in eclipse could be work, or what rules do I need consider for makefile for gcc arm?

Thanks for your advice and answer.

waiting for you.

jaski.tx · April 16, 2019, 2:43pm

hi @JesusP88

I am sorry for the delayed answer. Here is the makefile I used. Could you try on your side, if this works for you.

Best regards,
Jaski

JesusP88 · April 19, 2019, 3:34pm

Hi Jaski! Thanks again for your help, finally I could compile the “hello world example”, However the compile warning me, this is the output:

Description	Resource	Path	Location	Type
cannot find entry symbol Reset_Handler; defaulting to 000000001fff8000	gpio_demo		 	C/C++ Problem

Could you explain me this? please.

In the following section I put my steps in eclipse for future revision in this community.

1.- The version of eclipse that i used: Eclipse Neon 3 (neon-3) eclipse build Id = 4.6.3.M20170301-0400

2.- I’m using Ubuntu 16.04 x64

3.- export the path :~$ export ARMGCC_DIR=${HOME}/opt/gcc-arm-none-eabi-7-2017-q4-major/ and run eclipse from this shell ~/eclipse/neon-3/eclipse$ ./eclipse

4.- I create a makefile project File>New>C project

5.- I selected Empty project > ARM Cross GCC

[upload|q0NE7VOuU0Q5ggvCmmaYNvtjElM=]

6.- Set the ARM gcc downloaded from this post

[upload|4Z5d3XOg2+8AqVoOkYXQHWYSZms=]

7.- I create the tree folder project for rtos

[upload|9rLXLHDjy25WOkKaMYpeLsmaICQ=]

8.- I added a make file to project.

make file with a little change

9.- out put compilation:

Jaski I did not upload the elf file into Cortex M4, before that, with the all last step, Do you consider that the compilation process was good? If you think that the compilation process was good I will upload the elf file inside M4.

Waiting for your feedback. thanks.

BTW: The name project is wrong because I compile the hello world example, not gpio.

// Create a demo task which will print Hello world and echo user's input.
    xTaskCreate(HelloTask, "Print Task", configMINIMAL_STACK_SIZE,
                NULL, tskIDLE_PRIORITY+1, NULL);

Hi

Hi Jaski! Thanks again for your help, finally I could compile the “hello world example”,

These are good news. Perfect that the compilation was successful.

However the compile warning me, this is the output:
cannot find entry symbol Reset_Handler; defaulting to 000000001fff8000 gpio_demo C/C++ Problem

This is strange. I would check this and come back to you.

Jaski I did not upload the elf file into Cortex M4, before that, with the all last step, Do you consider that the compilation process was good? If you think that the compilation process was good I will upload the elf file inside M4.

Actually the compilation process finished with one warning, so you can upload the .elf file into M4.

Best regards, Jaski

JesusP88 · May 4, 2019, 5:57pm

Hi Jaski! Any news about

cannot find entry symbol Reset_Handler; defaulting to 000000001fff8000 gpio_demo C/C++ Problem

Thanks.

jaski.tx · May 9, 2019, 2:31pm

Hi @JesusP88

Could you check if the symbol Reset_Handler is defined somewhere in your Project or not? The best way is to do the grep -ri Reset_Hanlder command.

Best regards,
Jaski
