Hello, I would like to know from this group on how could I activate my last semester miniproject m68hc11A1 minikit. I have read the the HC11 book and browse through the websites but I am still quite confused about the concept of startup procedure. I would be very grateful if somebody expert from this group could explain to me in a simple way Thank you for your participation --------------------------------- |

I know nothing of a "minikit", I suggest contacting the
manufacturer for technical data. Since you hint that this is a university project, I also suggest that you contact your tutor for guidance. Having said that, I go on to describe the usual method for starting up (bootstrapping) an unprogrammed MC68HC11. The HC11 contains a small 'bootstrap' loader in ROM. See the White Book, Section 3, especially Section 3.7.4 "Special Bootstrap Mode" and its subsections for details of operation. There is available special debug and programming software which can be run on a PC compatible host computer that knows how to operate the HC11 in bootstrap mode and download and program the devices. These programs require a serial communications connection between the PC and the target HC11. Two examples of such software are PCBUG11, available at the Motorola MCU website and JBUG11 available at http://freespace.virgin.net/john.beatty/Jbug11_main.html You may also want to consider joining the Jbug11 email group at YaHoo.

Actually we name it as minikit since it is our mini project that we build
from fresh components. As mentioned in the book (I have HC11 rev 3 with me), the
M68HC11A1 has ROM disabled. So how about the bootstrap loader? Robert Smith <> wrote:I know nothing of a "minikit", I suggest contacting the manufacturer for technical data.

In a message dated 3/30/04 3:04:11 AM Eastern Standard Time, writes: Actually we name it as minikit since it is our mini project that we build from fresh components. As mentioned in the book (I have HC11 rev 3 with me), the M68HC11A1 has ROM disabled. So how about the bootstrap loader? ========================================= I have used several hc11 models in bootstrap mode.... hc11e2,f1,d0 and e0... there are subtle differences in how the boot program works, but they are clearly described in a moto app note on the moto site. The bootstrap program just waits for an $FF to come in the serial port at 1200 baud, then will load a binary program into ram, then jump to the start of ram after either a pause of 4 character times, or after 256 bytes have been loaded into ram. The pc basically just does a file transfer of the little binary bootstrap program out the serial port at 1200 baud. (The various flavors of hc11 have ram at different locs, and regs at different locs, so the boostrap program is specific to the processor type) After the bootstrap program has been booted into ram, it starts running. The program booted is usually a rom burner program that will read s-records in from the serial port and burn them into rom byte by byte. The simpler programs run at 1200 baud because this is slow enought to allow a 10ms per bte burn as the next chars are arriving. The company that makes the little 'Micro Stamps', Technological Arts, provides both programs for all their products and a windows program to control the whole thing, but the boards that we make on our own I wrote the bootstrap prog in assembler and just download it with a bat file that copies it to com1. What model of hc11 is used in the minikit? Maybe one of the techarts bootloaders will work. The imagecraft hc11 c compiler ide also has a boot download option. |

Some things that come quickly to mind. 1. Do you have the PCBUG11 documentation including the latest revisions? Have you read it? If so, then pay particular attention to the sections showing how to interface PCBUG11 to a PC. 2. Is your communications cable connected correctly and working? How is the mini-board configured? If DTE, are you using a crossover cable? If DCE, are you using a straight through cable? 3. Have you jumpered the MCU to start up in special bootstrap mode? Does the MCU send BREAK after RESET? Does PCBUG11 respond with $FF and then send the program? 4. Do you have the correct crystal frequency installed. Do communications take place at the correct baud rate? 5. Have you configured PCBUG11 for your CPU? Do you have the correct talker selected? I have not used PCBUG11 in a long time so my memory of how to get it to go the first time is rather fuzzy. I use Jbug11 these days.

One further thought has occured. Are you possibly using a USB to RS-232 converter on one of the new computers that come complete without serial ports. I know of at least two of these devices that do not handle the BREAK sequence correctly. Since BREAK is common to most Motorola debug start up sequences, it is not possible to use these converters with such debuggers. If this is the case, get yourself an old, unloved, legacy machine with _real_ RS-232 ports and try again.

Hi, Does anyone know about a tool that can convert 68hc11 assmebly code into C code?The assembely code was written to be assembled with A6801 IAR assembler? thanks anees -----Original Message----- From: Robert Smith [mailto:] Sent: Thursday, April 01, 2004 8:38 AM To: Subject: Re: [m68HC11] To activate m68hc11 minikit Some things that come quickly to mind. 1. Do you have the PCBUG11 documentation including the latest revisions? Have you read it? If so, then pay particular attention to the sections showing how to interface PCBUG11 to a PC. 2. Is your communications cable connected correctly and working? How is the mini-board configured? If DTE, are you using a crossover cable? If DCE, are you using a straight through cable? 3. Have you jumpered the MCU to start up in special bootstrap mode? Does the MCU send BREAK after RESET? Does PCBUG11 respond with $FF and then send the program? 4. Do you have the correct crystal frequency installed. Do communications take place at the correct baud rate? 5. Have you configured PCBUG11 for your CPU? Do you have the correct talker selected? I have not used PCBUG11 in a long time so my memory of how to get it to go the first time is rather fuzzy. I use Jbug11 these days.

While translating C syntax to assmebly/machine code is a difficult task, translating in the opposite direction would be considerably more difficult. While I can envision some possibilities for translating well-behaved asm code into something roughly C-like, I have a hard time imagining any tool that could do this reliably and accurately for all possible cases. The code that such a theoretical tool would generate would likely be less readable and comprehensible than the original assembly source. I am afraid that your only real option if you want to maintain an existing project written in assembly language is to either continue to work in the asm environment, or re-write the code in C by hand. |
