Re: Stack size and overflows

But this would have been coughed by the state checker if you had enabled debugging, wouldn't it? :twisted:

Re: STM32 Ethernet Demo

You are using the lwip RAW API, which is forbidden when using LwIp with an operating system. You have to use netconn or sockets. I think it is the other way around. The RAW API is the only one usable without an OS, because it does not require threads and synchronization stuff, but of course can be ...

Re: The SPC5xx/MPC5xxx topic

I am confident this new IDE has an enormous potential. I am just a bit worried about the current lack of a really free compiler and debugger for PPC. Wait. There isn't even a working gcc for it? Can't we just use standard PPC? EDIT: Found these: http://www.cygwin.com/ml/crossgcc/2003-04/msg00009.ht...

Re: The SPC5xx/MPC5xxx topic

Yeah, also noticed this earlier. So these are under "ST Liberty SW License Agreement V2", so you are seriously working with ST? From what I have read from the licence, I don't like it that much but OK :twisted: As long as you think it is compatible with the GPL code? In any case, it's very...

Re: Is chibiOS the right choice for me?

Hmm I think the feature matrix is "only" for the stable version. You might have to you the development branch - but it is generally quite stable. The problem is that there is no GPL exception for development code. But I'm sure you can figure something out with Giovanni.

Re: Is chibiOS the right choice for me?

An external RAM connected via the FSMC I'm not sure this has been done yet - but it will be simple, I guess. An LCD connected via the FSMC There is the ChibiOS/GFX subproject which might fit your requirements. Tectu is the man to ask here. Also for commercial aspects. A camera connected via the DCM...

Re: STM32 Ethernet Demo

After some issues I've got working stm32f4discovery with DP83848. Thanks for mabl and tkj! I got ARMCM4-STM32F407-LWIP demo, changed link to ST_STM32F4_DISCOVERY board. After, I thoroughly checked board.h, assigning right alternate function values according datasheet. Great! I'm sure you also learn...

Re: [RFC] Ideas for ChibiOS/RT 3.0

Good idea, but I am not sure it can be easily "standardized" and abstracted. For example, in my current project I need tons of data packages timestamped with uS since Unix epoch. The mS resolution is good enough so I use virtual timer and int64 counter. It increases every tick and correct...
