Perform the following actions
DEMO BOARD CONFIGURATION
- Set the POWER switch in OFF position
- Connect a USB cable between demo board and PC. If an RS232C cable is
present, the USB interface is selected by default
- Configure the power jumper accordingly to power source wich supplies the demo
board
- Set the POWER switch in ON position.
-- While holding down the ISP switch, press and release the reset switch to invoke
the ISP mode
(Note : don’t miss this step as it is very important to work around a USB bug when
invoking the ISP mode)
--> Result : PWR ON led is switched on and ALE led is blinking
--> Trouble shooting : Check if 8 Mhz quartz is correctly fitted
PROGRAMMING EXTERNAL E2P
- Run FLIP
- Select part at8xc5122
- Establish a USB communication
---> Results : if a Software Security Error windows comes up, just click OK. This
windows just warns that the part security bit is activated. In this case, an erase
operation is mandatory before programming the part
- Select Erase, Blank Check, Program and Verify options
- Load the user code into FLIP buffer
- Edit FLIP buffer
- Configure the area from 07FFD to 07FFF according to the wanted options (Refer
to bootloader datasheet). A common configuration is :
07FFD = 08h
07FFE = MSB (user code size)
07FFF = LSB (user code size)
- Select Whole buffer in buffer options menu
- Click on Run button
- Click on FLASH Start Application button to execute the user code
- Check if E2P code is correctly executed after a power on or a reset operation
AT89STK-03 Hardware User Guide
Comments
- Setting hardware condition
P3.7=0 during power on or reset
will force the bootloader to enter
in ISP mode with FLIP
- DRV bootloader supports E2P
write functions to program the
external E2P.
- The area from 07FFD to 07FFF
can be configured by means of
FLIP’s GUI. It is recommended
to check the configuration by
editing the FLIP buffer from
07FFF to 07FFF
