C firmware compile

[smythe]

Some engineers at our company wrote some firmware for our embedded hardware device. In short, they are no longer with the company and I need to figure out how to compile the firmware.

I normally do development in visual c++, but I need to compile the c so I can generate a "Motorola S Record" format which is flashed to the device.

Here is the chip in our embedded device:

I don't know how to do this, I need help. Is this something I can do with GNU compiler? Where do I get a compiler? Any help would be greatly appreciated.

Here is the makefile I found:
# -lc12p

CC = icc12w
CFLAGS = -DDEBUG -Ic:\\progra~1\\icc12\\include -e -l -v -Wf-cpdon
LFLAGS = -Lc:\\progra~1\\icc12\\lib -m -btext:0xc000 -bdata:0x0800 -bextcode:0x0.0x1FFFF -dinit_sp:0x0c00 -fmots19
OBJS = main.o gpio.o eeprom.o soundbank.o version.o update.o security.o termio.o queue.o vectors.o

.c.o:
$(CC) $(CFLAGS) -c $?

impro: $(OBJS) usb_lib imcore_lib i2c_lib
$(CC) -o impro $(LFLAGS) $(OBJS) -llp12p -lc12p -lusb -limcore -li2c -lspi


usb_lib:
cd usb; make all

imcore_lib:
cd imcore; make all

i2c_lib:
cd i2c/asm; make all

clean:
rm -rf *.o *.s19 *.lis *.lk *.s *.dp2 *.src *.lst *.mp *.i *.a

Compiler for which processor ? <nbucska@pcperipherals.com>

Hi,
I was actually able to notice the &quot;ICC12&quot; in the makefile, I found that is a C compiler so our engineers must have been using the software/path. I'm experimenting with a demo version from

Here is hardware related info:

The MC68HC812A4 microcontroller unit (MCU) is a 16-bit device composed of standard on-chip peripheral modules connected by an inter module bus. Modules include a 16-bit central processing unit (CPU12), a Lite integration module (LIM), two asynchronous serial communications interfaces (SCI0 and SCI1), a serial peripheral interface (SPI), a timer and pulse accumulation module, an 8-bit analog-to- digital converter (ATD), 1 Kbyte of RAM, 4 Kbytes of EEPROM, and memory expansion logic with chip selects, key wakeup ports, and a phase-locked loop (PLL). 1.1

Features:

Low-Power, High-Speed M68HC12 CPU
