Common Error Messages
If the programming box is not connected to the PC USB
interface then the programmer will return a “USB connection
Error!” as shown in figure 9 when an attempt is made to read or
write to the A4963. If the driver is loaded there is no need to
stop and restart the program. Just connect the box to the PC via
the USB cable and the programming operation can resume.
Ifthe driver is not loaded then stop the program, load the driver
and restart he programmer.
Note that if the programming box is correctly connected and
an attempt is made to read without an A4963 in the socket the
programmer will return the data as x0FFin all registers.
If a compare error occurs during the verification process then
an additional “EEPROM Data Error” window,as shown in
figure 10, will appear showing the contents read back from the
EEPROM. If an attempt is made to program an empty socket
then the data read back will be displayed as “FFF” in all
registers. Click “OK” to dismiss the “EEPROM Data Error”
window and return to the programming window where the
status “EEPROM Verify Error” will be displayed.
