• If no LED is lit solid and the red FAIL LED is flashing, the micro-controller encountered an invalid con-
Great care has been taken to choose very simple LED patterns for those result codes that are exceedingly
likely to occur in a production environment, that is result codes 0, 1, and 13. All three of these results are
indicated by a single lit LED with the other two status LEDs in the off state. This way, a production floor
operator can quickly glance at the board and immediately classify the result as WAIT, FAIL, or PASS. The
other error codes are either limited to Development mode, setup errors (which would be caught prior to
an operator taking over), or are rather unlikely to occur.
Result Code Details
• 0 (Programming in progress) - This result code really means that programming is not finished, and no
• 1 (Success: no error) - The DUT was programmed successfully and no errors were encountered.
• 2/3/4 (Warning: OTP configuration violation) - DEVELOPMENT MODE ONLY - One or more OTP con-
• 5 (Invalid: no configuration file found) - The micro-controller has not received a valid configuration file.
• 6 (Invalid: no DUT found) - The micro-controller was unable to find a DUT on the board. This means
• 7 (Invalid: DUT is not a CS2000 family device) - A DUT was found on the board, but it doesn’t appear
• 8 (Invalid: unsupported revision) - The revision of the CS2000 family device found is not supported.
• 9 (Error: register read error) - The firmware encountered a register read error. Most likely, this indicates
• 10/11/12 (Error: OTP configuration violation) - PRODUCTION MODE ONLY - One or more OTP con-
• 13 (Error: OTP read-back error) - The DUT was programmed, but OTP read-back verification failed.
• 14 (Error: general or unknown error) - A miscellaneous error occurred. This could indicate a defective

figuration violations were encountered, but programming continued on a best-effort basis. The offend-

the DUT before proceeding.
The firmware can only program CS2000 family devices of revision B2 or above. Revisions B1 and be-

a defective DUT. You may try to invoke the programming sequence again. If the error persists, replace
the DUT before proceeding.
figuration violations were encountered, and the DUT was not programmed. This error indicates either
an invalid configuration file or a configuration file that doesn’t match the DUT variant currently present
on the board. Make sure the configuration file was created for the proper target DUT, and verify the
correct DUT variant is present.
This error indicates a defective DUT that must be replaced.
DUT or a problem with the board hardware or the micro-controller firmware. You may wish to try again,
first with the same and then with a different DUT. If the error still persists, a hardware problem is pos-
sible.
