What's the deets on the Cortex-M3? Is that accessible to the end user, or is that blackboxed and NDA'd? (Cough cough, IPM... >_>!) How's this stock up to the BBB as far as power usage goes? What's the supply chain look like for your silicon? Planning to maintain stock at the distributors? Any plans for a non/through hole? Exposing the ethernet and MDIO pin headers for another SD card would be awesome. (Props for putting USB on the headers, and keeping the underside empty!) Edit: Looks like you're planning more on using this as a demo-board for your chip. Does powering the chip from the LiPo handle the RTC, so I can stop dropping a DS1307 onboard? ;)

The Cortex-M3 is for power management. You can find details from TI (http://processors.wiki.ti.com/index.php/Debugging_AM335x_Suspend-Resume_Issues http://processors.wiki.ti.com/index.php/Debugging_AM335x_Sus... http://processors.wiki.ti.com/index.php/AM335x_Linux_Power_Management_User_Guide http://processors.wiki.ti.com/index.php/AM335x_Linux_Power_M...). The OSD335x-SM uses the same power management solution as the BBB. The chip itself will consume less power than the BBB since it doesn't have all the additional peripherals. We currently have stock as DigiKey and Mouser and will maintain stock. If you have additional questions on supply, feel free to contact us (https://octavosystems.com/contact/ https://octavosystems.com/contact/) We do have other development boards for this processor (https://octavosystems.com/octavo_products/osd3358-sm-red/ https://octavosystems.com/octavo_products/osd3358-sm-red/) more expensive, but more features. There are still some issues around RTC. The PMIC that we use (TPS65217C) doesn't support RTC-only mode, so unfortunately, you will still probably want to use the discrete RTC to get the standby time you need.
