Description Command Answer
See if a program is installed (in this case a avrdude) fab@fab-desktop:~$ which avrdude /usr/bin/avrdude
Install a program fab@fab-desktop:~$ sudo apt get install gvrasm [sudo] password for fab: //Insert Fab Password
Run the program in this case gavrasm fab@fab-desktop:~$ gavrasm
  • Follow the track and check every component voltage (capacitor, voltage regulator)
  • Check the solder there is no electrical continuity
  • If the solder is ok, replace the component (Learn here how to un-solder properly)
Change Directory fab@fab-desktop:~$ cd Desktop
List Files fab@fab-desktop:~/Desktop$ ls
Run the gavrasm to transform asm file to a ".hex" file (hexadecimal) fab@fab-desktop:~/Desktop$ gavrasm hello.RGB.45.MTA.asm
Run the Avrdude comunicate to t45 using the parallel port fab@fab-desktop:~/Desktop$ avrdude -p t45 -c bsd -U flash:w:hello.RGB.45.MTA.hex avrdude: can't open device "/dev/parport0": Permission denied 
  failed to open parallel port "/dev/parport0"
List [ls] paralel port with detail [-l] (crw-rw----) fab@fab-desktop:~/Desktop$ ls -l /dev/parport0 crw-rw---- 1 root lp 99, 0 2010-01-14 11:30 /dev/parport0
Change permission to access parallel port, and insert fab user password fab@fab-desktop:~/Desktop$ sudo chmod 0766 /dev/parport0 [sudo] password for fab:
List [ls] paralel port with detail [-l] and check the permission differences (crwxrw-rw-) fab@fab-desktop:~/Desktop$ ls -l /dev/parport0 crwxrw-rw- 1 root lp 99, 0 2010-01-14 11:30 /dev/parport0
Run the Avrdude comunicate to t45 using the serial (com) port and install the hexadecimal program "hello.RGB.45.hex" fab@fab-desktop:~$ avrdude -p t45 -c dasa -P /dev/ttyS0 -U flash:w:hello.RGB.45.hex
Run the Avrdude comunicate to t45 using the serial (com) port and install the hexadecimal program "hello.RGB.45.hex" if you aren't in the directory where the file is. In this example is w:/home/fab/Desktop/hello.RGB.45.hex == fab@fab-desktop:~$ avrdude -p t45 -c dasa -P /dev/ttyS0 -U flash:w:/home/fab/Desktop/hello.RGB.45.hex AVR device initialized and ready to accept instructions

See if a program is installed (in this case a avrdude)

Command: fab@fab-desktop:~$ which avrdude Answer: /usr/bin/avrdude

Install a program

Command:fab@fab-desktop:~$ sudo apt get install gvrasm Command:[sudo] password for fab: //Insert Fab Password

Run the program

Command:fab@fab-desktop:~$ gavrasm

Change Directory

Command:fab@fab-desktop:~$ cd Desktop

List Files

Command:fab@fab-desktop:~/Desktop$ ls

Run the gavrasm to transform asm file to a ".hex" file (hexadecimal)

Command:fab@fab-desktop:~/Desktop$ gavrasm hello.RGB.45.MTA.asm

Run the Avrdude comunicate to t45 using the parallel port

Command:fab@fab-desktop:~/Desktop$ avrdude -p t45 -c bsd -U flash:w:hello.RGB.45.MTA.hex

Answer:avrdude: can't open device "/dev/parport0": Permission denied

Answer:avrdude: failed to open parallel port "/dev/parport0"


List [ls] paralel port with detail [-l] (crw-rw----)

Command:fab@fab-desktop:~/Desktop$ ls -l /dev/parport0

Answer:crw-rw---- 1 root lp 99, 0 2010-01-14 11:30 /dev/parport0
