RIOT usage with msp430 and stm32fdiscovery

Development archive
#1

Hello devel team,

I forward my question to you. I’m having some issues compiling the project sixlowpan for msp430, due to some basic functions that are missing (like stdin and sscanf).

Have you compiled this project for the ws430-v1_4 board? if yes, wich compiler version are you using?

The same for the stm32f4discovery board, since the compiler version that you propose in the “Getting started” guide is not compatible with cortex-m4 architectures.

Thanks in advance!

Best regards.

Hi,

Have you compiled this project for the ws430-v1_4 board? if yes, wich compiler version are you using?

I tried this, with the msp430-gcc version 4.6.3, however the compiler complained of about 16k missing. I do not think there is any chance to get the current 6lowpan implementation on a msp430f16xx.

for stm32f4xx i use : "GNU Tools for ARM Embedded Processors" https://launchpad.net/gcc-arm-embedded.

I fully agree with Kaspar and I think this should be an important goal for the next release. I guess the planned refactoring of the network stack will help us a lot to see where the memory is wasted.

However, when I try to build the sixlowpan project for the wsn430-v1_3b platform, there are "just" 3kB missing.

Hi Francisco,

I forward my question to you. I'm having some issues compiling the project sixlowpan for msp430, due to some basic functions that are missing (like stdin and sscanf).

the missing stdin for MSP430 based platform is a known issue: https://github.com/RIOT-OS/RIOT/issues/21

But since all platforms should have a working UART driver by now, this seems easily solvable.

sscanf is missing, too, but can be replaced: https://github.com/RIOT-OS/projects/pull/34

The missing ssize_t goes into RIOT with https://github.com/RIOT-OS/RIOT/pull/195

The next missing thing is the missing calloc() for MSP430, but this should be pretty easy to solve, too.

Cheers, Oleg

Hi Oleg,

Thank you so much for the answers, now I subscribed to the mailing list, so I can receive the messages by myself.

I'm having that issue about the memory, so I'll see if we can do some optimizations for reducing code size. However, we have some documentation about this example? Maybe I can adapt the code only to my needs and run my application example for the experiment that I'm trying to deploy.

Thanks again!

Cheers,

Francisco
