TI AM335X Windows Embedded Compact Bootloader Args: Passing between eBoot and the OS

In this blog, the eBoot menu is modified to to allow user selection of Clearing of the Hive or not. This is implemeneted by adding a further parameter to the BOOT_CG and BSP_ARGS structures to handle the boolean selection. The eBoot code is then extended to pass the selection up to the OS args driver. The OS args driver then is modified to get the value when requested by getting it from the structure passed to it through shared memory. This replaces the use of the dummy variable s_bClearHive  as used in args.c in the previous blog.

Avago buys Broadcom for $37 billion

Broadcom is best known for its wireless and connectivity chips used by the likes of Apple and Samsung in their smart phones.

It also makes the ARM processor used in the highly popular Raspberry Pi platforms. As I mentioned in a previous blog posting, Microsoft is targeting this platform as one of the Windows 10 IoT core platforms. It will be interesting to see how things shakeout.

TI AM335X Windows Embedded Compact Bootloader Args and Clearing Hive Registry

The previous blog in this series demonstrated how to add a custom OAL IOCTL to the BSP. In particular it implemented the IOCTL_HAL_GET_HIVE_CLEAN_FLAG IOCTL so that it returns a fixed value to the OS when called. In this blog, that code is extended to call the BSP boot args using a custom boot arg. A fixed value is returned by boot args  in this case. A later blog will pass that arg from eboot.

TI AM335X Windows Embedded Compact Bootloader and Custom OAL IOTCLs

OAL IOCTLs are callable from OAL code to perform specific functions within the OS Kernel. The OS requires the OEM to specifically implement certain IOTLCs that it calls, and some other standard IOTCLs if implemented are automatically called by the OS. One such optional IOCTL, IOCTL_HAL_GET_HIVE_CLEAN_FLAG, will cause the OS to clear the hive registry if it passes back a TRUE when called at OS startup. These IOCTLs are normally called in kernel mode as they are called directly by the the kernel. Some IOCTLs can be called by a user mode thread as well.  In our book, Professional Windows Embedded Compact 7, I covered implementing a custom OAL IOCTL for the VCEPC BSP. This blog looks at adding an OAL IOCTL with the ARM TI AM335X  BSP

Internet of Things “wrap up” : events, slides, libraries and …. demo with a lot of code !!

Last month I developed a lot and I had the pleasure of being speaker to three national events and an international one in California (but from remote).I was greatly involved to write code and content that I decided to summarize hoping that you could enjoy them. With the slides I tried to describe the most important features of the Azure Service Bus focusing on the Event Hubs and its use within the telemetry pattern in IoT :Event Hubs : million events per second to the Cloud (MEC Internet of Things Conference 2015 in Naples)Event Hubs : million events per second to the Cloud (Global Azure Bootcamp, OC community California) of which it is also available the video here on YouTubeMicrosoft e l’IoT (M2M Forum in Milan, session with Roberto Andreoli and Erica Barone from Microsoft Italia)Azure Service Bus : under the hood (IoT Day in Venice)These slides have related demos where I used my last Azure SB Lite library, thanks to which you can access to the Microsoft Azure Service Bus using the same API of the "o ...

Windows 10 Iot of Raspberry Pi 2 First look

Windows 10 IoT version is the latest lightweight flavor directed at small embedded devices. Previewed at Build 2015 and prereleased as “Windows Core Insider Preview”. it will be interesting to see just how this product will be received. This initial released is directed at the “Maker” community which is quite a change for Microsoft as this segment is not perceived as a large profit center unlike its traditional targets. While the Raspberry Pi is a very popular platform in the Maker community it is still mostly used for small “one of” type projects. It is popular in academic circles and used by many institutions as an introduction platform for beginner programmers. Unfortunately the hardware is very “closed source”, there are no schematics or PCB layout information available and virtually no information on the SoC chip used. True it is a powerful quad core 900Mhz ARM Cortex-A7 processor from Broadcom but if you look on their web site you won’t find any mention of the part nor any information on the part what ...

Windows 10 IoT Systems


Various scenarios were presented for Windows 10 IoT at Build 2015. In all cases, the object is to have a Windows 10 device, whether desktop, mobile or embedded/IoT, talking to custom hardware and to the cloud. The “reference” design for hardware from a Makers’ perspective is Arduino. Let’s examine the scenarios.

About Windows 10 IoT

Windows 10 IoT is the third (lower) layer of Windows 10. All three are built from the same codebase, part of Microsoft’s one Windows mantra. Whilst the desktop will have significantly more features than the IOT layer, the IoT layer will embedded features such as General Purpose IO (GPIO) which the desktop doesn’t. The Phone layer will support cellular networks for phone calls whereas the other two only support this for internet access. Apart from the common code, a binding feature of all three is Universal Apps.
