ColdFire

• Set CFM configuration region in image programmed to internal flash ($400-$417). Without this, the MCF5282 can't boot from internal flash. You need this bug fix if you boot from internal flash.

SwiftX 3.2.8 (08-Feb-2005)

ALL

• Modified serial port XTL to handle both CR and LF codes correctly in the debug window.
• Factored out common XTL functions.
• Corrected stack comments in numeric output operators.

ARM

SwiftX/ARM has undergone extensive improvements. Please read this list carefully for notes on updating your existing projects.

• Updated SwiftX/ARM target reference manual.
• Added support for STMicroelectronics STR7 (ARM7 based) microcontrollers on the STR710 EVAL board.
• XTL debug interface to all ARM targets is now via JTAG. This frees up the serial port and no longer requires preserving the manufacturer's monitor program in flash. An inexpensive ($30) JTAG cable is available from us.
• Improved LDRI assembler macro to load the literal value using a PC+ Rd LDR instruction. END-CODE has been extended to compile the list of literals and update the references in the LDR instructions). This means that LR is no longer used (so doesn't need to be preserved just for LDRI) and each literal reference requires one less instruction. Further, multiple loads of the same literal value within the same code definition or subroutine will all reference a single copy of the literal. Note that LDRI now assembles a simple MOV instruction if the literal value can fit in the (possibly shifted) 8-bit literal field of the opcode.
• The improved LDRI has been incorporated into LITERAL which similarly improves high-level definitions. The table of literals is compiled by ; (just as END-CODE does for code definitions and subroutines).
• The disassembler has been extended to display these literal values as '<lit> LDRI' instead of the less meaningful '<offs> PC+; Rd; LDR'.
• With the addition of the ST ARM family, the ARM source code has been reorganized. An additional level of source subdirectories has been inserted below SwiftX\Src\ARM for the vendor-specific source code. At present, these include Atmel AT91 and STMicroelectroncs STR7 families. The board-specific project directories are now subordinate to their respective vendor-specific directories. Important: Your project files may need to be updated to reflect this change in source code organization. Please use the Kernel.f files in the board-level project directories as a reference.

All target reference projects have been updated with the PRAM code sections removed. Important: Load your test code between SET-DOWNLOAD and DOWNLOAD-ALL so it is correctly downloaded to target flash. Entering flash-resident definitions on the command line is not recommended.
• Added support for the FET430P120 tool with the MSP430F1232 part installed.

SwiftX 3.2.0 (28-May-2003)

NEW FEATURES

• IDATA sections are now optional. If no IDATA section is declared, all accesses to IDATA will use the current CDATA section instead. This is especially useful for systems that boot into RAM and do not have separate code and data spaces. This feature may not be used for targets that have separate code and data spaces (e.g. 8051, AVR).
• Manual port selection is not provided on the Tools menu for targets that connect to the host parallel port. Used by ColdFire (BDM cable), 68K (CPU32 parallel BDM cable), MSP430 (parallel JTAG cable), AVR (parallel 'dongle' ISP cable), and TMS32C3x (parallel boot loader cable).

68HC11

• Added runtime code for 8- and 16-bit literals, reducing the size used by inline literals.

68HC12

• Corrected EEPROM base address in 9S12DP256 register definition file. Note that in the 9S12DP256, only 3K of the total 4K EEPROM is accessible. The first 1K is overlayed by the I/O register space.
• Added support for downloading to the Motorola D-Bug12 serial bootloader. This only applies to parts with the D-Bug12 serial bootloader resident in the flash. The host function PROGRAM-BOOTLOADER can be called to download the most recently generated S-record file to the target. Follow the prompts for the download procedure. This is best done immediately after a BUILD.

68K

SwiftX 3.1.12

ALL

• Factored out common XTL source code from most targets with serial XTL. Common code is in SwiftX\Src\XTL.f and must be included in your target's KERNEL.F if you use the serial XTL code in the SwiftX\Src\<mcu> directory. See one of the sample target board KERNEL.F files for an example. Does not apply to systems with BDM or JTAG debug interfaces.
• Added .' ("dot-tick") and data logging functions to the common serial XTL source. .' is described in the SwiftX Reference Manual Section 2.4.3. The target can pass buffers of binary data to the host to be written to the file TARGET.LOG in the working project directory. See the SwiftX Reference Manual Section 4.9.3 or LOCATE X-LOG for more details on this XTL extension.
• Generate Motorola S-record files for object files with the ".M*" extension in addition to the existing ".S*". This has been done primarily to support the Hitachi FDT utility which uses ".MOT" as the file extension for Motorola S-record object files.
• Generate TI "text" files for object files with the ".T*" extension. This output file format is compatible with TI tools.
• Fixed INTERPRETER COMPARE function.
• Updated SwiftX reference manual.
• Added commands to the Help menu in the Debug Window to display the revision history (the file you are reading right now) as well as to go online to check for newer versions and revision history.

68K, ColdFire, MSP430

• Changed the installation procedure for GiveIO driver (Windows NT, 2000, and XP systems only) such that the driver is installed as a kernel service which always starts at boot time. This is handled completely by the SwiftX installer. You must have Administration priviliges to install SwiftX. LOADDRV.F (Pro systems only) is no longer needed and has been removed from the Xcomp directory.

ColdFire

• Added internal I/O device vector names for MCF5272 to Reg_5272.f after register definitions.

H8

SwiftX for the H8/300H and H8S has undergone extensive improvements. Please read this list carefully for notes on updating your existing projects.

• Added support for the H8/3664F evaluation kit (EDK3664F). Modified all Reg_<mcu>.f files to support this change. Notably, the vector size, operating mode, type of SCI, and flash programming parameters have been added.
• Added support for both normal and advanced mode processor cores. Reg<mcu>.f must declare [NORMAL-MODE] or [ADVANCED-MODE]. The load order for all KERNEL.F files has been changed so the Reg file is loaded much earlier due to the mode setting requirement. You must declare the mode before compiling any kernel code! Include the Reg<mcu>.f file early in Kernel.f.
• Added assembler macros POP.A and PUSH.A which assemble the correct form (.L for advanced mode or .W for normal mode) based on the CPU mode declaration.
• Replaced the various combinations of SCI support for XTL debug interface use the generic SCIXTL.F driver which supplies the port-independent XTL debug interface. Select which SCI port is to be used as the XTL in your CONFIG.F file. See the H8 SwiftX manual, Section 3.4 plus any of the supplied target board CONFIG.F files for examples. You must specify the SCI port to use for the debug interface.
• Replaced the various combinations of SCI support for terminal task I/O with the generic SCITERM.F driver which supplies the port-independent terminal I/O routines. Please read the H8 SwiftX manual, Section 3.4 and the documentation header block of SCITERM.F for notes on using this driver.
• Added user code to program the SwiftX kernel into target flash memory using the H8 bootloader. It is necessary to reset the CPU in BOOT mode before using this facility; see the H8 SwiftX manual section A.3.2 for the procedure for the EDK3664F. You must have access to the MD and FEW (or FWP) settings when you reset the CPU in order to enter and exit BOOT mode. The file SwiftX\Src\H8H\BOOT.F must be included in your KERNEL.F load file. See SwiftX\Src\H8H\EDK3664F\KERNEL.F for an example. Please read the documentation header block of BOOT.F for notes on using the flash programming feature. The only two end-user accessible words are RELOAD and RELOAD! which perform conditional and unconditional flash updates.
• Reduced the common stack and user area allocations (|S|, |R|, and |U|) to better support the H8 Tiny devices.
• Modified LITERAL such that it assembles a call to (LITERAL) which gets the in-line literal data that follows the call. This conserves code space when compared to the previous method of in-line code for literals.
• Recoded the double return stack operators (2>R, etc.) to save space.
• Added the Distress Signal ("S.O.S.") demo for the H8/3664F board which does not have enough resources to support the standard "Conical Piles" demo. This demo is described in the H8 SwiftX manual section 4.4.
• Fixed SHLL.L opcode in assembler.
• Generate Motorola S-record files for object files with the ".M*" extension in addition to the existing ".S*". This has been done primarily to support the Hitachi FDT utility which uses ".MOT" as the file extension for Motorola S-record object files.

MSP430

• Fixed address range check in test for substitution of <addr> # BR with JMP. If the address passed to # BR is within relative branch range, it is substituted with the shorter JMP instruction.
• Added UART terminal I/O drivers in SwiftX\Src\MSP430.Uarts.f. Read the documentation at the start of the file for details on how to use it.
• Generate TI "text" files for object files with the ".T*" extension. This output file format is compatible with TI and SoftBaugh tools.
