ChibiOS Free Embedded RTOS

Hi,

Yes, it is a nice device. Cannot give a deadline however.

Giovanni

Does that F3 demo compile in your MDK?

Giovanni

It looks like you assembler does not use the C preprocessor so all macros and comments cause errors, look for an assembler option for that.

Giovanni

Hi,

You need to enable C99 compatibility in your compiler.

Giovanni

It is simple, each STM32 has different versions of some peripherals.

You need to look into .\ChibiOS_21.11.3\os\hal\ports\STM32\STM32F1xx\platform.mk, the list of the LLDs to be included is in there.

Giovanni

Hi, Easiest way is to look for the .mk files in the various subsystems and include the files specified in there, for example for RT look into rt.mk. About which subsystems include, look into a Makefile where all .mk are included. There is also an F3 project for MDK under /demos/STM32, you may start ...

You should try to identify which layer causes the delay, there are several, is the MAC driver delaying frames ? does it happen in lwip ?

Giovanni

Some partial work has been committed in trunk but I cannot guarantee a delivery date, have fun with your project

Giovanni

Hi,

Do you have threads slowing down lwip threads? check priorities order.

Giovanni

Hi,

It is possible this is related to this old bug:

https://sourceforge.net/p/chibios/bugs/973/

Could you try that proposed fix?
