GNU binutils

Tuesday 8 September 2026, by 63F09 // Tools

A 63F09 port has been added to GNU binutils, including as (assembler), ld (linker), gdb (debugger) and a disassembler. As A09 was the first assembler for 63F09, GNU binutils were tortured until A09 and binutils produce the same binary outputs.
GNU binutils can be downloaded in section files.
To obtain a 63F09 toochain, configure script has to be run with —target=m6809. Read more »

A09

Tuesday 28 May 2024, by 63F09 // Tools

A09 assembler can be downloaded in section files.
This assembler generates code for various processors including: MC6809; HD6309; 63F09 (in 32 bits mode, with or without FPU).
When 63F09 mode is selected, A09 creates a 32 bits HEX or S-record output. As memblkcs.rpl waits for 32 bits S-record file, A09 should be called with:
./a09 -L -oF09 -S i2c.asm
to create: S315FFFF0000113D3110CEFFFE0000CEFFFDF00010C800 S315FFFF0010FFFE10C6B086009702CC0000DD04CC00C1 (…) Read more »
