ChibiOS Free Embedded RTOS

The board definition STM32F103C8_MINIMAL already in ChibiOS sources should work for a Blue-Pill with a real STM32.

Nice tool!
Just a note, when downloading the zip, it seems that my browser (Firefox) thinks it is a plain text document and try to open the zip in text editor... Maybe a MIME type issue?

I agree, Synology NAS are very versatile and plug-n-play. If you want something more open there are free systems to turn a Linux box into a NAS like OpenMediaVault : https://www.openmediavault.org/ or FreeNAS : https://www.freenas.org/ On the hardware side, the Helios4 seemed nice : https://kobol.io...

I agree with you.

When I did my rosserial_chibios I used the version found in lwip_binding but it is not very handy. Nice macros like in RT would be nice.

I have used the USB of a cheap chinese 407VET6 recently, maybe this could help you: https://github.com/romainreignier/BLUE_ ... ni_ChibiOS

I have tried to use the MPU feature but without success. Even on a simple RT-STM32F401RE-NUCLEO64 demo, modified to generate a stack overflow, the MPU feature does not trigger anything. See the attached picture where the "compute thread" stack overflow on the blinker thread working area so...

Ok, great for MPU, I will make sure to test it soon! NIL without semaphores and CH_CFG_ST_TIMEDELTA not 0 does not build: ChibiOS/os/nil/src/ch.c: In function 'chSysTimerHandlerI': ChibiOS/os/nil/src/ch.c:373:17: error: 'union <anonymous>' has no member named 'semp' tp->u1.semp->cnt++;

Yes, I am using trunk from last month. Even without MPU, I was able to reduce RAM usage to 15 kB! But the stack checker did not help me, do I need to enable another option to use it? As I understand, a stack overflow should be detected and the OS halted? Instead, the application was just working wit...

Ok, thanks but PORT_USE_MPU_REGION need to be defined.

Thanks for the advises.

But I am not sure, what do you mean by "MPU guard pages"? Is there any example how to use that feature?
