Limitations

Evaluation Kits are code-limited and have the following restrictions:

ARM Evaluation Tools

• You may not use the Evaluation Version of the µVision IDE/Debugger to create commercial products.
• Programs that generate more than 32 Kbytes of code and data will not compile, assemble, or link.
• The debugger supports programs that are 32 Kbytes or smaller.
• The tools are time-limited and cease to run a few months after installation. If your tools have expired, install the latest release of the Evaluation Tools to reset the expiration date.
• The compiler does not generate a disassembly listing of the machine code generated. The -S, --asm, and --interleave compiler command-line options are disabled.
• The compiler and assembler do not generate position-independent code or data. The --apcs /ropi /rwpi /pic/ pid compiler and assembler command line options are disabled.
• The assembler and linker create Symbolic Output Format objects which cannot be linked with third-party linker utilities. Fully licensed tools generate standard ELF/DWARF files which may be used with third-party utilities.
• The linker does not accept scatter-loading description files for sophisticated memory layouts. The --scatter command line option is disabled.
• The base address for the code and constants in memory must be 0x000080000, 0x000100000, 0x000200000, 0x000300000, 0x000400000, 0x010400000, 0xXX000000, or 0xXX800000 (where XX is a Hexadecimal number from 00-FF). When the base address is 0x0 the linker places the code at the start of on-chip Flash of most ARM processor-based microcontrollers.
• The vector table, reset handler, and library initialization code are linked at the base address. The remaining user code and constants are offset from the base address by 0x4000 (16 KBytes). Programs generated with the Evaluation Version of the tools may not be programmed into single-chip devices with less than 16 KBytes of on-chip ROM/Flash.

C51 Evaluation Tools

• You may not use the Evaluation Version of the µVision IDE/Debugger to create commercial products.
• The 8051 compiler, assembler, linker, and debugger are limited to 2 Kbytes of object code. Source code may be of any size.
• Programs that generate more than 2 Kbytes of object code will not compile, assemble, or link.
• The debugger supports programs that are 2 Kbytes or smaller.
• The startup code generated includes LJMPs. Code generated cannot be used in single-chip devices that support 2 Kbytes or less of program space.
• Programs start at offset 0x0800. Programs generated with the evaluation software may not be programmed into single-chip devices with less than 2 Kbytes of on-chip ROM.
• No hardware support for multiple DPTR registers is provided.
• No support for floating-point arithmetic and no support for user libraries is provided.
• No support for in-line assembly using #pragma ASM.
• The following components which are present in the PK51 Full Version are not included in the Evaluation Version: Linker for Code Banking, Library Manager, and RTX51 Tiny Real-time Operating System.

C251 Evaluation Tools

• You may not use the Evaluation Version of the µVision IDE/Debugger to create commercial products.
• The 251 compiler, assembler, linker, and debugger are limited to 2 Kbytes of object code. Source code may be of any size.
• Programs that generate more than 2 Kbytes of object code will not compile, assemble, or link.
• The debugger supports programs that are 2 Kbytes or smaller.

C166 Evaluation Tools

• You may not use the Evaluation Version of the µVision IDE/Debugger to create commercial products.
• The C166 compiler, assembler, and linker are limited to 4 Kbytes of object code. Source code may be of any size.
• Programs that generate more than 4 Kbytes of object code will not compile, assemble, or link.
• The debugger supports programs that are 8 Kbytes or smaller.
