ChibiOS Free Embedded RTOS

Hi Giovanni,

Thanks for the reference, I'll look at it more closely when I have time.
The usbcfg.c file looks to be much better done than most others I have seen elsewhere.

However using IAD's was one of the approaches I did try. The issue with Composite devices seems to be that the Host needs ...

Hi again,

Thought I would provide an update.

I got ST's USB implementations for both MSC and CDC working on STM32F407 and STM32L476.

MSC was reasonably straight forward, since I am quite familiar with STs driver issues on uSD and eMMC (quite a number of bugs unfortunately).
They have 2 (well ...

Hi,

I am no longer working on this right now, but thought the heritage of the various Device MSCs initiatives and some other observations might help someone else.

There seem to be 2 main code sources that all the MSC prototypes that I uncovered stemmed from:
1) mabl (= Giovanni?) - released Mar ...

Hi Russian,

I have also been trying to get this working, however with very little success so far.

I looked through your code, but I can't quite tell which version of usb_msd.c/.h you are using.
The ones in your git are from chibios 2.6.8 which are a few years old and quite different from the ones ...

Hi Giovanni,

In terms of using ST's HAL entirely and only Chibios OS/RT, that is NOT what I was considering, but if you look at ST's interfaces for FreeRTOS.
It is a pretty thin interface, so likely would not be a huge effort.

However in my opinion, the value of Chibios is in its HAL plus RT, so ...

Hi,

ST has an extensive set of USB Host and Device Classes implemented, and they appear to be working and well done (although I have not verified this).

Has anyone ported or considered porting this library to Chibios? I couldn't find much in my searching of this forum, hence my post.

In looking ...

Here is a full set of IAR and project files with all corresponding changes to make work in both trunk and latest 16.1.x.
It has been tested on the olimex board to verify FatFS, USB CDC, shell, OS test execution and general behavior.
The web server also appears to be working, but I did not test it ...

Hi,

In testing LwIP, had an issue with chThdCreateStatic hanging, if CH_CFG_NO_IDLE_THREAD = TRUE.

In the lwip_bindings/lwipthread.c lwipInit code:
/* Creating the lwIP thread (it changes priority internally).*/
chThdCreateStatic(wa_lwip_thread, sizeof (wa_lwip_thread),
chThdGetPriorityX() - 1 ...

Hi,

OK, now that you mention it I do see note.txt files in ADC and DMA but no others.

And wrt to the SDIO vs SDMMC, that is unfortunate, since the code seems almost identical other than the naming and clearly defined ifdef code paths. I guess I'll find out pretty soon if the SDC abstraction works ...

Hi,

Some related questions to this.

Other than the platform.mk for each processor family, which describes which LLD peripheral version to use for that processor,
is there any documentation on what the different are between the versions other than doing diff's on the code?

For example, I have made ...
