We're getting ready to do a new DG256B design and I'm planning on using an 8M crystal. Our previous designs have used oscillators. There isn't anything in the...

Thanks Jeff, I may wind up using an osc anyway, since this device has to be Industrial grade and I'm not sure I want to try to take into effect temp, humidy,...

yeah.. no problem with crystals here on DP256B's just like jeff said.. But I like XO clock sources better.. ... -- Peter Fetterer KB3GTN The force is like duct...
... In order to take benefit from --gc-sections you probably would need to use --ffunction-sections when compiling. I, however, don't know if this works for...

Hello list members I'm working on a project that uses the 9s12 Motorola microcontroller. Until yesterday I was working with release 2.2 of the GNU tools when...

First of all, thanks for your fast answer. I compile with C:\usr\m6811-elf\bin\gcc.exe -c -ffast-math -fshort-double -ffixed- z -Wall -fomit-frame-pointer...
I don't know if it's your problem, but you have to erase all modules and completely recompile. The older release didn't properly generate type flags or...
Thanks, Jefferson. I think it's not the source of the problem, as I always delete the old .o files for this project (I have to generate to slightly different...

I believe you are on the wrong list. The task as defined involves assembly language, not C code. Unless you have been assigned to use GNU AS assembler, you...
If you have absolutely no debug ports and no way of displaying information, then yes, you will need a full emulator. If, however, you have access to a serial...
