90 Neuron C Compiler Errors (NCC)
NCC# Description
353 Variable being declared is too large for RAMNEAR. Use 'far'. [NCC#353]
The variable being declared is larger than 256 bytes in size. The total
available size of the RAMNEAR area in the Neuron is 256 bytes, thus this
variable declaration
must be placed in RAMFAR. Use the far keyword in
the declaration ("near" is the default). See Chapter 8 of the
Neuron C
Programmer's Guide
for more information.
354 Variable being declared is too large for EENEAR. Use 'far'.
The variable being declared is larger than 255 bytes in size. The total
available size of the EENEAR area in the Neuron is 255 bytes, thus this
variable declaration
must be placed in EEFAR. Use the far keyword in the
declaration ("near" is the default). See Chapter 8 of the Neuron
C
Programmer's Guide
for more information.
357 The 'uninit' storage class requires use of 'eeprom' or 'config' or ‘cp’ [NCC#357]
The uninit storage class is used to tell the compiler not to provide any
initial value for the data item being declared, thus the loader will not
overwrite that area of memory when reloading the program. This feature is
only available for data items using EEPROM or Flash memory (the uninit
storage class does not apply to RAM variables). The uninit feature requires
the declaration to use one of the storage classes eeprom, config, or
config_prop (abbreviated cp). See the
Neuron C Programmer’s Guide for
more information.
358 The 'offchip' storage class requires use of 'far’ [NCC#358]
The Neuron Chip provides a “near” area of EEPROM memory and a "near"
area of RAM memory. Each of the “near” areas is located onchip, and
“near” is the default memory area used by a data declaration. When
writing a program for a Neuron 3150, which has external (off-chip)
memory, the offchip keyword can be used in the data declaration to force
the linker to place the data item in offchip memory. Since the data
declaration would default to the near area, which is located on-chip, the far
keyword must also be used in the data declaration. Add the far keyword to
the declaration.
See Chapter 8 of the
Neuron C Programmer’s Guide for more information
on managing memory resources.
359 The keywords 'offchip' and 'onchip' are mutually exclusive [NCC#359]
As the message states, at most one of these storage classes may be used in
a data declaration.
