	~~:'''Q: How can I access the bootloader u-boot console?'''~~
	:'''A:''' It is not possible to enter to the bootloader console by pressing a various key (e.g. "Enter") on your keyboard. You have to send "DEL" (ASCII 0x7F) to the device. We recommend you to use the terminal program '''teraterm''' if you are working on windows and to use '''kermit''' or '''minicom''' if you use a linux operating system on your pc.
	~~:*You can configure teraterm to send "DEL" when the delete key or the backspace key is pressed by clicking through the menu to <code> Setup->Keyboard-Setup </code> and enable the required checkbox.~~

	~~:*Kermit is sending a "DEL" if you hit the backspace key.~~

	:*Minicom is able to send "DEL" when you hit the backspace key if you configure minicom to do that within a terminal window: run <code> $ minicom -s </code> and navigate to <code> Screen and keyboard </code> press "B"

	~~:'''Q: The automatic update is not executed before the operating system boots!'''~~
	:'''A:''' Check if the command <code> update auto </code> is included in the bootloader environment variable <code>bootcmd</code> or in a script-variable which is called within <code> bootcmd </code> before <code> bootm </code>.

	~~:'''Q: The automatic update does not work with my desired update-media!'''~~
	:'''A:''' The command <code> update auto </code> can be configured with flags within the DHCOM settings.bin block. It is possible to disable a interface for the update mechanism. You can run a update from a disabled interface if you use the command <code> update </code> without the argument <code> auto </code>.

	~~:'''Q: Which USB Port should i use to run updates with the bootloader?'''~~
	~~:'''A:''' Our systems are designed to run updates via the DHCOM USB Host 1 interface. We can support additional usb nterfaces on request.~~

	~~:'''Q: My usb flash memory device is not recognized by the bootloader!'''~~
	:'''A:''' The are limitations when you use usb flash memory devices with u-boot. Please check that a master boot record is available and that a FAT32 filesystem is used on the first primary partition of the device.
