I have a c code , i need to execute that program in M4 processor using linux terminal. Can anyone please guide me how to do it?
Hi @Goutam bhat, have you looked to our documentation? http://www.udoo.org/docs-neo/Arduin...no_M4_from_Internal_Processor(Cortex-A9).html
For bare metal programming you could look here for a couple of directions: http://www.udoo.org/forum/index.php?threads/3086/
i dont want to use arduino sketch. Is there any way to execute C program without using arduino sketch using linux terminal only? Please give the solution
In the documentation link Andrea gave is the following instruction which does exactly what you want: Precompiled binary It's possible to upload a precompiled binary firmware on the M4 using this command: udooneo-m4uploader.sh <BINARY_PATH>
Can you please say me what is precompiled binary firmware? Is it the object file which we get after compilation of C program? If not then how to get precompiled binary firmware of C program. Please guide me
Yes that is the object file after compilation. To get a compiled object file please follow the link I already gave you. If you have more questions about that please ask the questions in that thread. There is no guide available. There are some examples in the he NXP forum and documentation. The link is in the other thread.
Walters/Andreas advice isn't all correct (and confusing), if want to run 'C' code on the M4 your options are to either develop your application using FreeRTOS or MQX. The compiled binary should only be loaded onto the M4 using uboot, if your attempting to do this after the A9 has booted Linux then your asking for problems. The bare metal approach for running code on the M4 isn't recommended for novices due to the complexity of initialising the M4 before running your application code. In fact all the approaches require you to get up to speed with the boot process for the i.mx6sx and understanding the heterogeneous architecture which can be found in the Reference Manual. If the above isn't making much sense then you have a steep learning curve to achieve your objective.
Hello jas, can you please say me how to install FreeRTOS in UDOO neo ,I downloaded the tar file but didnt how to proceed further.Waiting for your response Thank you.
After you unpack the tar, there is a doc directory which contains Getting_Started_with_FreeRTOS_BSP_for_i.MX_6SoloX.pdf thats you should read. You need to install gcc-arm-none-eabi. Then first thing to you need to do is amend the board.h file in examples/imx6sx_sdb_m4 to support the peripherals for the Neo and try to build an example for that board. The debug UART is already configured correctly so your PRINTF should output to the M4 serial debug port. If the above doesn't make much sense the your learning curve is going to be steep.
