How to flash dsp firmware for digital/fx filter boards

Discontinued products Shruthi
#1

hello mutable community,

i am actually building a Shruthi with digital/fx filter boards,already did the hardware part,seems ok get +5v where it should be on the filter board,
so now i try to flash dsp firmware on the 328p since 2 two days but with no sucess…not very familiar with this so i tried by myself but i should say that
i don t understand everything about PATh and git
I am using a atmel avrisp2,i download all the things as said there http://mutable-instruments.net/shruthi1/firmware.
downloaded Shruthi-1 master folder at github unzip it on my desktop
well i plug the filter board with 9v ,the programmer to the isp header,get the green light on the programmer,
i tried to sets the fuses looks like workin

avrdude -B 100 -V -p m328p -c avrisp2 -P usb -e -U lock:w:0x2F:m -e -u efuse:w:0xFD:m -U fuse:w:0xD7:m -U lfuse:w:0xFF:m -U lock:w:0x2F:m

i get

avrdude:1 bytes of lock wirtten
avrdude done. thank you.

so after i try with this

avrdude -B 1 -V -p m328p -c avrisp2 -P usb \\ -U flash:w:dsp_0.1.hex:i -U lock:w:0x2F.:m

but that part not workin,so i tried to document myself but still no sucess,so i come here to get some help.
i know it s a lack of knowledge.
thanks for your help

> but that part not workin

What happens?

#3

thanks to answer so fast :slight_smile:
when i put the second command line i get:

avrdude: device signature= 0x000000
avrdude: yikes ! invalid device signature .
double check connections and try again or use -F to override this check.

avrdude done.thank you.

#4

I have no idea how you came up with the first command line to set the fuses:

-e -U lock:w:0x2F:m -e -u efuse:w:0xFD:m -U fuse:w:0xD7:m -U lfuse:w:0xFF:m -U lock:w:0x2F:m

There are two erase flags (?), one missing U flag (?) and no reference to hfuse. The command should be:

-e -u -U efuse:w:0xFD:m -U hfuse:w:0xD7:m -U lfuse:w:0xFF:m -U lock:w:0x2F:m

#5

sorry,i made a mistake
i didn t get the fuses set before,
now with your command line it s workin for the fuses
so i put the second one

avrdude -B 1 -V -p m328p -c avrisp2 -P usb \\ -U flash:w:dsp_0.1.hex:i -U lock:w:0x2F.:m

and i have

avrdude :device signature=0x1e950f
avrdude: safe mode :fuses ok
avrdude done.thank you

so from this point i dont understand what i must do now

#6

> i dont understand what i must do now

Nothing. With this last command the firmware is written. Did you see the “Writing: ##########” progress bar? Did it go up to 100%?

#7

ok,but ,now i have a reading ########## progress bar it goes to 100%
not a Writing: ##########” one

#8

Hey, what about posting exactly what you see on your screen? Like a screenshot of the command line? How am I supposed to help if you keep this all for yourself?

#9

ok sorry ,

The command is either:

avrdude -B 1 -V -p m328p -c avrisp2 -P usb -U flash:w:dsp_0.1.hex:i -U lock:w:0x2F:m

Or:

avrdude -B 1 -V -p m328p -c avrisp2 -P usb \\

-U flash:w:dsp_0.1.hex:i -U lock:w:0x2F:m

#12

I run the command line now it goes closer to the truth got this:

avrdude: AVR device initialized and ready to accept instructions

#13

Have you downloaded dsp_0.1.hex and put it in the directory from which you are running the commands?

#14

I think i must specify where is the .hex files,how you do this i am block at this point…

#15

i downloaded it yes i got it as text file is write in hexadecimal,
it s this point that i don t understand,when you mean,
"put it in the directory from which you are running the commands"
must make this step from the terminal?

#16

You are running the commands from your home directory, so put the .hex file in your home directory.

#17

did it but i think it s the problem is the .hex i save it as dsp_01.txt.hex,
thanks for your attention

#18

i think i found i do this :

MacBook-Pro-de-bernie-5:~ bernienoel$ avrdude -B 1 -V -p m328p -c avrisp2 -P usb -U flash:w:dsp_0.1.hex.txt:i -U lock:w:0x2F:m

hope i am right can you confirm ?
