Thread is read only, therefore starting another one for MCB1000 HID and Binary Files...
\Keil\Arm\Bin\ELFDWT.exe will exactly do that - create the checksum and put it into the given .axf file:
C:\Keil\arm\bin\ElfDwt abc.axf C:\Keil\Arm\bin\ElfDwt abc.axf BIN(abc.bin)
The first example creates the checksum and 'patches' file abc.axf. The second example does the same and additionally creates a .bin file where the checksum is patched as well. This can be used for loading via mass storage device.
The ElfDWT.exe utility is part of the recent MDK.
If "thread" is read-only, so you start a new thread - shouldn't you link to the original thread? Do you think that 6 months from now (when this thread is also read-only), a visitor from Google land will be able to guess which thread you are thinking about?
