Error and Warning Messages
(489) psect * memory delta redefined: */*
A global psect has been defined with two different delta values, e.g.:
(490) class * memory space redefined: */*
A class has been defined in two different memory spaces. Either rename one of the classes or, if they
are the same class, place them in the same memory space.
(491) can’t find * words for psect "*" in segment "*"
One of the main tasks the linker performs is positioning the blocks (or psects) of code and data that is
generated from the program into the memory available for the target device. This error indicates that
the linker was unable to find an area of free memory large enough to accomodate one of the psects.
The error message indicates the name of the psect that the linker was attempting to position and the
segment name which is typically the name of a class which is defined with a linker -A option.

blocks. This error can be due to two reasons.
selected device. In other words, some part of your device’s memory has completely filled. If this is
the case, then the size of the specified psect must be reduced.
positioned is sufficient, but that this memory is fragmented in such a way that the largest contiguous
block is too small to accomodate the psect. The linker is unable to split psects in this situation. That
is, the linker cannot place part of a psect at one location and part somewhere else. Thus, the linker
must be able to find a contiguous block of memory large enough for every psect. If this is the cause
of the error, then the psect must be split into smaller psects if possible.
information on how to generate a map file. Search for the string UNUSED ADDRESS RANGES. Under
this heading, look for the name of the segment specified in the error message. If the name is not
present, then all the memory available for this psect has been allocated. If it is present, there will be
one address range specified under this segment for each free block of memory. Determine the size
of each block and compare this with the number of words specified in the error message.
