5	Firmware upgrade through USB*	USB device firmware upgrade class supported. The device complies with the USB device firmware upgrade standard.	This is very useful when you just want to update the entire OS image by just connecting a USB A to B cable to the PC and through some key sequence you would want to upgrade the OS. An application pops on the PC and the user can choose the firmware file to be downloaded.
6	Eboot prompt	Eboot prompt is supported on any of the serial ports. The debug port is configurable	Useful during development when download has to be done or during production when diagnostics has be done.
7	LEDS – Software controllable	Yes	The LEDS can be controlled through software and is used for debugging purpose.
8	CPU speed change command support	Yes. CPU speed can be configured for either of 312/416/520.	Helps in testing the performance of the application under various processor speeds.
9	Kernel boot options	Supports kernel boot via NOR flash, NAND flash and also on the external SD card.	Users can choose to boot from SD card if they can use this as a field upgrade tool for their firmware and the OS.
10	JTAG	Supports boot code flashing through JTAG	An application is provided in the PC to flash the boot code via JTAG

Kernel level

S.No	Feature	Support	Remarks
1	Debug and release version of builds	The default build comes up with a working debug and release version binaries.	Debug build is needed for inserting break points etc. The release build is just 6 MB in size and includes a full windows CE shell with driver support for all the on board peripherals.
2	Active KITL and Passive KITL	Yes
3	Kernel Debug messages	The debug messages shall appear on the serial port. The serial port is configurable	User can choose the serial port wher e the debug messages can be done. Alternatively the port can also be disabled and used for application purposes. For more info visit www.e-consystems.com/blog/debugport/ .
4	KITL interface	KITL interface is supported via USB client, Ethernet and Serial.	User can choose which interface they want to use for debugging. Some devices might have Ethernet and may not have USB slave and some might not have either of Ethernet or USB slave and hence support of KITL over Serial becomes important. Please see the Regulus KITL startup user manual and Regulus KITL application debugging document for more info.
5	Kernel debugger	Inserting and removing break points can be done at any point in the kernel code.	Helps when building custom device drivers
6	Debug zones	Yes	Helps when building device drivers
7	Profiling	CElog and kernel profiling support is provided	Helps when you face performance issues with the driver and you would want to see where you spent most of your time on the CE kernel.
8	Ethernet driver support	Supported. It is a 10/100 Ethernet driver with performance of up to 20Mbps in UDP traffic using iperf.	Application support for DHCP as well as static IP is provided.
9	USB Host - USB Mass storage	Support for memory stick up to 8GB is provided	Tested with Kingston USB drive up to 8 GB.
10	USB Host – HID class	Support for Keyboard, mouse is provided
11	USB device – Active sync	Support for syncing devices to the PC.	Sharing files and folders between the PC And the device can be achieved. Active sync has sync features using which you do not need to physically copy the files.
12	USB device - Mass storage support	On plugging the device to the PC, the device will act like a mass storage	Useful for devices like digital camera or any other device where the end user has to just have access to the data storage on the device.
13	USB device – Composite*	The device shall show multiple properties like active Sync and mass storage also. This will be done simultaneous	Useful when multiple properties of the USB device has to be supported simultaneously.
14	NAND flash – Storage	The device will appear as a storage device. Supports up to 1GB in storage	Support for SLC NAND flash.
15	NAND flash – bad block reporting and management	The bad blocks are reported in the boot time and the driver manages the bad blocks and the ECC correction.	Bad block management is important as NAND flash on usage the blocks become bad and it becomes critical to have a robust driver an file system.
16	NOR flash – Storage	The device will appear as a storage device.
17	CF card – storage**	Drivers shall be provided for acting like a storage device.
18	SD card – Storage	Supports SD high capacity storage up to 16GB.
19	SD – Wi-Fi	802.11b ad 802.11b/g cards are supported. Iperf test results are available.	This is available as a add on module to the Sirius and regulus platforms.
20	SPI driver	There is no SPI device but the SPI interface is exposed as a header in the reference platforms Sirius and regulus. e-con provides sample SPI drivers for a EEPROM like device on the SPI port.	Customers can use this sample driver source to build the drivers for their SPI devices. e-con has supported several customers for building their own SPI drivers on top of Windows CE. Application level API is provided for read and write through SPI interface. Please see Regulus SPI LIB document and Regulus sample SPI driver document for more information,
21	I2C	Yes provided.	There is a RTC that sits on the I2C interface(On Regulus) and hence the driver can be used to write drivers for I2C devices. In case of Sirius, a sample I2C driver is provided. Please see the I2C API Document for more information.
