ChibiOS Free Embedded RTOS

Thank you for the response. I will let you know how integration goes when we start the process.

I'm interested in the STM32F4 demo of the NASA cFE OSAL. I see the osapi.c and PSP files within common/abstractions/nasa_cfe, but can you tell me more about how this integrates with the actual NASA cFE source code to build the firmware with everything integrated? I have experience building cFE for ...

Thanks, that makes sense.

I have been working with the new I2S driver checked into the 3.0 branch, and so far have been receiving audio from an external wolfson codec. What I am trying to do is write the data coming in from the wolfson to a file with FatFS using the I2scallback function that is placed into the i2sconfig ...

Just to add a note, when I plug the modem into Ubuntu it shows up as as a ttyACM device.

Any idea on what host class the driver would have to support? I see within the STM FW lib for USB Host they have MSC, DualCore, and HID. I wouldn't think that the modem would want to connect to any of those device classes?

Does anyone know if it is possible to communicate with a modem via AT commands from the USB CDC interface? The modem operates only in USB device mode with the USB pins available being D+, D- and USB Voltage. Using the USB CDC driver in Full Speed mode would be my ideal solution, but is it required ...

I will try to integrate this into my project soon for testing and will report issues/findings. Looking through the driver I don't see anything that stands out as non-compatible with the 2.6 kernel, is this correct? I'd like to integrate this into my 2.6.3 project. Thanks for the post notifying me of ...

Great work, however it is missing an implementation for wf_printf().

Interrupts are being fired but everything in the DMA Memory0 location is garbage data. I checked the SPI2 DR register and it is always 0 when DMA is enabled. I hooked a scope up to the I2S pins and verified PCM data is being transferred. The I2SCFGR register looks accurate when reading it during DMA ...
