Firmware for AduC70xx ARM microcontrollers can be uploaded using built in boot-loader. To work with boot-loader Analog Devices offer to use small free program ARMWSD working under windows system. Program doesn’t require installation. ARMWSD communicates with AduC70xx via COM-port. Simple programming steps looks like this:

• Connect target board to PC COM port;

• Go to Configure->Parts and select AduC part:

• Then go to Configure->Comms and select serial port and baud rate:

• Select other settings if needed (Mass erase, Program, Verify, Protect) in Configure->Flash menu;

• Press OK to get to main window again. Browse for hex file – only hex files are supported in this program. When you are set, then press Start button - Program starts waiting for boot-loader action:

• Now you have to start boot-loader on your target board. As you know entering boot-loader needs some procedure to be done. Manually you have to press button “Download” connected to BM pin, then power on board and rapidly press and release “Reset” button and then release “Download” button. After this AduC70xx enters boot-loading mode and downloads hex file.

Program is simple but it does the job.
