12. Troubleshooting
Q1: My Software Development Board (SDB) displays an error message on startup.
A1: Factory firmware is designed to operate with officially approved testcards. The EBID (see Figure 20, “Test Card
Characteristics EEPROM (EBID),” on page 17) contain an authentication code to enable the use of the testcard
with the factory firmware.
Note: The EBID is only used in conjunction with factory firmware. EBID restrictions are not implemented by default
in customer firmware.
Figure 67. Error Message
The standard error message highlights
1. A missing testcard
2. A missing EEPROM
3. An invalid EEPROM authentication code
In addition, the firmware revision is highlighted in order for technical support to assist you.
Q2: After the Silicon Labs splash screen (which contains the firmware revision), there is an additional screen
shown before the setup menu's - What is this for?
A2: Authentication codes in the EBID enable the Silicon Labs to qualify a factory firmware build to a particular
testcard. If you received these message screens then a testcard is either an engineering testcard or is a specially
modified testcard for specific customers. Customers that have opened a technical support request and that have
special requirements may have received modified testcards—in this event, a notification will be displayed.
