Table 9-2. IPL Error Messages
Error Description
Invalid Image This error occurs if another record is received before the
Header Record. Ensure the Header Record is the first record
downloaded.
Partition Not Defined The destination code is a part of the Header record and is used
as an index into the partition table. The partition table entry
located at this index contains partition information for the data
downloaded. If the Auto Select option is selected, a check is
made to ensure that valid partition information exists in the
partition table at this index. The check verifies that the Area
Name and Sector Size are both non-zero. If not, this error
occurs.
Wrong Partition If a specific partition is selected from the partition list, and the
destination code of the Header record downloaded does not
match the index of that partition, this error occurs.
Image Too Big The size of the image is also part of the Header record. If the
data to be written exceeds the size of the partition as indicated
in the partition table, this error occurs.
Incorrect Byte Count Image data is processed until the End Of File (EOF - Record
Type 01) record is received. This error occurs if IPL detects
that the number of bytes received does not equal the number
of bytes sent.
Unable to Verify Partition
Data If the Receive and Verify bit is set for that partition, the data
(the Flash sector erased and the data written to the Flash part)
is verified. If this data can not be verified, this error occurs.
Transmission Errors The following error messages may appear if an error occurs
during transmission:
• “Checksum Error” occurs if an invalid checksum is
detected in the record.
• “Invalid Record” occurs if a record is not defined in
the Symbol Hex File Format.
• “Connection Lost” occurs if one of the handshaking
lines is de-asserted during download.
• “Address Out of Sequence” occurs if the address of
the data received is not sequential.
