Re: NASA OSAL Demo

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

NASA OSAL Demo

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 L...

Using new I2S Driver

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 obje...

Re: USB CDC to Modem AT Interface

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

Re: USB CDC to Modem AT Interface

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?

USB CDC to Modem AT Interface

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 t...

Re: I2S/SPI DMA RX from audio chip not firing interrupts

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...

Re: FatFS Wrapper

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

Re: I2S/SPI DMA RX from audio chip not firing interrupts

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...
