... Hash: SHA1 ... Does using int32_t here change things? - -- Daniel O'Connor software and network engineer for Genesis Software - http://www.gsoft.com.au ...
... Actually, it looks like a similar problem to what someone else had recently. The compiler was doing 16 bit math on an initializer for a 32 bit number,...
Sorry about the incorrect subject before. The build process DOES care about the linker option! Make uses m6811-elf-as for n.s to n.o and m6811-elf-gcc as a...

I was looking for a way to avoid putting the LDFLAGS statement in the top level Makefile. After thinking about this, it appears not possible. The selection of...

Hi Tom, I've just started trying the FlashEraseSector function. With all good comes a bad I guess. The good news is that even not fully understanding how it...
Remko, That usually happens when PPAGE and FCNFG are mot set right. See: PNT_FILE_HDR GetFileAddr(UINT logical) This crashes the hcs12 because you either...
I'm surprised a C programmer would not know the asm. That would be very valuable to you. May I ask what part is dificult, and I'll explain it? Just look at a...
John, I don't know what you mean by what part is difficult? I wrote my first program in 1963. I haven't been out of work since. I have been using Motorola...
Hi Tom, I'm starting to get how this works. I've managed erasing my first sector and programming a word in it without crashing! The idea behind all of my ...

Remko, You can have the WriteFlWord(), EraseFlSector() in EEprom or copy them to RAM to run. I have done both at times. This way you can do everything that...
Hi Tom, from eeprom will be fine for now but the copy to ram to run seems a more pretty sollution. I've used the __attribute__((section(".eeprom"))) to locate...
Remko, There are routines to write to EEprom in the functions in that package. I use it for my directory and free sector list. I am using a P&E BDM. They have...
Hey I found one used in the ColdFire. Just put the routines in the blocks labeled RAM and call the normal ones that copy them. The coldfire isn't the same, it...

Hi Tom, great! Many thanks for the source file. So far the EraseFlashSector works but I'm having troubles with the WriteFlashWord. The weird thing is that when...
