Thank you very much for sharing this work with us, I have no time no try it at
present, but I surely will need it in the future.
Let us know any update to this. How about uploading it to the "files" section of
the
group ?

I went and pulled an old map, and using my SMALL C compiler, and
the assembly I wrote for stdio, the total package for printf()
comes to 916 bytes, if I did the computation right. That includes
the full formatter and its dependencies, printf() itself, fputc(),
and implementations of stdin, stderr, and stdout tied to the SCI port.
It does "hang and wait" style I/O, not interrupt driven, and is
not multithread safe, as it uses a single "put back" character for
stdin, and has no mutual exclusion on access to the SCI; it just
reads the status port.

Whether my SMALL C back end does a better or worse job of generating
code than does the gnu compiler, I don't know. However, I suspect it
can't be much better, and possibly much worse. You'd have to port the
stdio package to work with the assembler gnu uses, or get someone else
to do that. I'm not familiar with that assembler.

Also, if you are using the '12, there might be some differences in how
the SCI works. I'm not familiar with the '12, but my code definitely
works with the '11.

If you don't need stdin, stdout, stderr, rawin, and rawout (the files
supported by my stdio package), but just need sprintf() then it could be
cut back by the size of the stdio package I did. That's 76 bytes
(including the "put back" character).

Well, it depends on having fputc(), if that's what you mean.
I can send you my implementation of stdout, stderr, stdin, and
fputc() if you like. They are all tied to the SCI port.

It's probably mostly in the other parts, then.

On list, you don't. If you are a member of the Yahoo!Group,
then there is a way to "upload" files into a files area,
which other members can see. I am not a member of any Yahoo!Group,
so I can neither upload nor view/download such files, so I
can't help you with that.

In this case, you could include the text in the body of your
message.

You are welcome. I edited up the other one I sent you so it
compiles and runs with ANSI compilers, along with a make file
to build and do a rudimentary test of each format it supports.

Are you asking "how to I set up the gnu-m68hc11 toolset" in order to
write a program which eventually gets stored in FLASH?

I have been away from 68hx MCUs for several years, but I am coming back, I used
to program the HC11, I have made the transition to the HC12 now, but I have one
little issue:
How do I program flash? I didn't mean to say "what tools" are needed to program
flash.
What I meant to say is: How does one set up a project to program the flash
memory?
I have a working program I could modify and adjust to my needs, but I want to go
beyond this: I want to know what I need to do to program flash.
I know I have to set up the interrupts vector table, I think I do know how that
can be done.
The reason I am asking this is because so far I worked with projects that
generated .s19 hex files, but I have noticed that flash programs are .s29
I did some online research, but there's very little information on how to use
the gcc compiler for flash programming.
Can someone give me information on what's needed to generate flash programs?
Thanks

Hi folks,

    I'm trying to build FreeRTOS "HCS12_GCC_banked Demo" and program the
MCS912DP256 on MC9S12DP256EVB board (http://tr.im/Fuo2). I have success on
building it (on ubuntu linux), but I could not program the microcontroller using
BDM Multilink Cable (http://tr.im/FunV) on Windows. Any tips?

Thanks!

If you are just turning an integer to a string you can do a simple hand
rolled version (especially if you can make certain assumptions about
sign, base, size, etc)

The smallest general purpose one I have used is in AVR libc, it has
several versions you can choose from at compile time.

13k isn't that bad for a printf really, especially if it has float
support. printf is a very complex beast!

I've sent you (under separate cover) one which does this:

However, note that while it recognizes 'h', 'l', and 'L', it does
nothing with them. All numbers are expected to be 16 bit integers.

I also included the source for fprintf(), printf(),
sprintf(), vfprintf(), vprintf(), and vsprintf()
along with their helper functions to work with the formatter.

Hmm. It also needs atoi(). The version I have I wrote in assembler
for the MC6HC11, and it isn't compatible with the gnu toolset.
You'll have to come up with an atoi() which is compatible with the
one I wrote.

I've got one, but it's stripped down. What formats do you need to

The compiler doesn't have *printf*, that's a libc thing (hence newlib).

Can you guys tell me if the stdio functions are included in the hc1x compiler?
I need to use sprintf to format a string and send it to an LCD.
I tried compiling a very simple program using sprintf but I got a boat load of
errors.
I haven't used the hc1x gcc compiler in a very long while.
I know that the gel library probably has those functions: printf, sprintf,

If anybody in this group has a small version of the standard sprintf, I would

Thanks to all.

I'm not sure why people are suggesting the use of Codewarrior - this is a group
for discussing GCC after all.

I've not used the Softec BDM recently, but I have a little experience of the P&E
BDM.

A friend of mine wrote a kernel module for it and was able to do some things
through gdb. Unfortunately it is quite rough at present and he has not completed
the code.

However, if others would be able to use the code as a starting point, I might
persuade him to release it.

It is not that board, but similar.

However I was looking for a solution that does not involve codewarrior,
more a gnu-hc12 solution.

Thanks again

I am just making a start with a softecmicro HCS12X Starter kit.

It has a USB to BDM interface which I have never come across before, dmesg
identifies the interface as:

usb 1-3.3: config 1 interface 0 altsetting 0 bulk endpoint 0x81 has invalid

Do we have a method of programming this?
