Cross-compiling for M4

Hi,

Can someone explain to me where to start if I would want to program M4 from my laptop and not the UdooNeo itself ?

1. Can I use GNU ARM Eclipse plugin ?
   • If so how do I get HAL part for M4 ?
   • How do I get access to peripherals ?
2. Can I use OpenOCD ?
3. How do I load code for Cortex-M4 on the core if I dont want to use Arduino ?
   • Is it just writing to specific memory area ?
   • Is that area protected by kernel ?
   • Are there tools uploading bin ?

Thanks

Dear @Mateusz,

1. You can use GNU ARM Linux to cross-compile UDOO NEO. This link will be useful to you:
   https://community.freescale.com/docs/DOC-103736 We've never done it anyway, so I can't walk you through this guide.
2. From A9 through UDOObuntu you can upload the code through this tool: udooneo-m4uploader

If you want to take a look at the code, here it is: https://github.com/ektor5/udooneo-m4uploader
You can definitely get UDOO NEO working with OpenOCD: http://allthingsembedded.blogspot.it/2016/01/udoo-neo-and-openocd-working.html

 

The code can be saved on udoo or should it be in sd card as we do in Uboot ?

 

Hi @Goutam bhat,
UDOO Neo doesn't have any eMMC, SSD, HDD or any form of memory storage.
You need the Micro SD.
However, before doing anything else I suggest you to give at look at the basic information about the board.
For example, the datasheet, which you can find the product page: http://www.udoo.org/udoo-neo/
I also invite to give a look to the "Getting started Neo" section of the website: http://www.udoo.org/get-started-neo/
