I am complete newbie I am following nerd guide

Failed at step 10 c page 43

after downloading latest Prolific driver and setting to usbserial as described on forum thread

I selected /initialload in terminal and entered make to get the following response in terminal

" unknown-10-9a-dd-9f-14-1d:Code simonwragg$ cd initialload unknown-10-9a-dd-9f-14-1d:initialload simonwragg$ ls Makefile initialload.c initialload.cBU unknown-10-9a-dd-9f-14-1d:initialload simonwragg$ make make -C ../libnerdkits avr-gcc -g -Os -Wall -mmcu=atmega168 -o delay.o -c delay.c avr-gcc -g -Os -Wall -mmcu=atmega168 -o lcd.o -c lcd.c avr-gcc -g -Os -Wall -mmcu=atmega168 -o uart.o -c uart.c avr-gcc -g -Os -Wall -mmcu=atmega168 -Wl,-u,vfprintf -lprintf_flt -Wl,-u,vfscanf -lscanf_flt -lm -o initialload.o initialload.c ../libnerdkits/delay.o ../libnerdkits/lcd.o ../libnerdkits/uart.o avr-objcopy -j .text -O ihex initialload.o initialload.hex avrdude -c avr109 -p m168 -b 115200 -P /dev/cu.usbserial -U flash:w:initialload.hex:a

The LCD just displays 2 lines of dark rectangles

I assume the delete has taken place but new program has not been downloaded

Any help appreciated

Hi swragg,

The most likely issue here is an issue with AVR Cross Pack that is dicussed in great length in this form post. The fix basically involves replacing one line in your Makefile:

avrdude ${AVRDUDEFLAGS} -U flash:w:initialload.hex:a

with

avrdude ${AVRDUDEFLAGS} -e
sleep 0.1
avrdude ${AVRDUDEFLAGS} -D -U flash:w:initialload.hex:a

I'd give that a try first.

The other possibility here is a dead or dying battery. Writing to the chip takes a lot of current, and a weak battery's voltage will drop enough to restart the chip and cause programming to fail.

Humberto

Thanks Humberto

rebooted comp, selected gcc4, changed makefile as suggested

" GCCFLAGS=-g -Os -Wall -mmcu=atmega168 LINKFLAGS=-Wl,-u,vfprintf -lprintf_flt -Wl,-u,vfscanf -lscanf_flt -lm AVRDUDEFLAGS=-c avr109 -p m168 -b 115200 -P /dev/cu.usbserial LINKOBJECTS=../libnerdkits/delay.o ../libnerdkits/lcd.o ../libnerdkits/uart.o

all: initialload-upload

initialload.hex: initialload.c make -C ../libnerdkits avr-gcc ${GCCFLAGS} ${LINKFLAGS} -o initialload.o initialload.c ${LINKOBJECTS} avr-objcopy -j .text -O ihex initialload.o initialload.hex

initialload-upload: initialload.hex avrdude ${AVRDUDEFLAGS} -e sleep 0.1 avrdude ${AVRDUDEFLAGS} -D -U flash:w:initialload.hex:a "

I then entered make

this was the response in terminal

" unknown-10-9a-dd-9f-14-1d:initialload simonwragg$ make make -C ../libnerdkits make[1]: Nothing to be done for `all'. avr-gcc -g -Os -Wall -mmcu=atmega168 -Wl,-u,vfprintf -lprintf_flt -Wl,-u,vfscanf -lscanf_flt -lm -o initialload.o initialload.c ../libnerdkits/delay.o ../libnerdkits/lcd.o ../libnerdkits/uart.o avr-objcopy -j .text -O ihex initialload.o initialload.hex avrdude -c avr109 -p m168 -b 115200 -P /dev/cu.usbserial -e

Maybe it isn't a butterfly/AVR109 but a AVR910 device? make: *** [initialload-upload] Error 1 unknown-10-9a-dd-9f-14-1d:initialload simonwragg$ "

Not sure what to do next

SORTED!!

I measured 7.8 volts across battery terminals

Replaced battery (As Humberto suggested)

ran make again - Success!
