This indicates that the file causing the problem was main.obj. This would be typically be the output
of compiling main.c or main.as. This tells you the file in which you should be looking. The next
number (8 in this example) is the record number in the object file that was causing the problem. If
you use the DUMP utility to examine the object file, you can identify the record, however you do not
normally need to do this.
for the value (1) , and the value which is the actual value the symbol represents, is typically the only
information needed to track down the cause of this error. Note that a size which is not a multiple of
8 bits will be rounded up to the nearest byte size, i.e. a 7 bit space in an instruction will be shown as
1 byte.
error message.
and to confirm, look for the symbol referenced in the assembler instruction at this address in the
symbol table at the bottom of the same file.
In this example, the instruction causing the problem takes an 8-bit offset into a bank of memory, but
clearly the address 0x1FC exceeds this size. Maybe the instruction should have been written as:
which masks out the top bits of the address containing the bank information.
bler list file look back up the file from the instruction at fault to determine which C statement has
generated this instruction. You will then need to examine the C code for possible errors. incorrectly
qualified pointers are an common trigger.
