I need to share something. You know about my serial problem, i am stuck at this but; when uploading sketches via parallel i am using some serial transfer sketches like serial RGB etc in this case serial is working normally i can send the data via serial and get the data via serial. But when i use serial for uploading sketches it didn't work. It isn't strange ?

Thanks.

[Fixed : Via Parallel Sketches is Uploading]

In hardware everything is OK no shortcuts no missing connections.
I choose the old board w/atmega8.
And also parallel programmer is working but when send sketches via parallel programmer sketches dont upload again. [glow]Fixed : Via Parallel Sketches is Uploading [/glow]
Btw i etch a second board its working too but i cant upload any sketches to it also .

Thanks for your helps.

Nope i dont mean that. TX led is lit continuosly when uploading, and rx led is little blinking but sketches dont upload the board. Same programmer error.

I think fixed the bootloader issue now when reset button is pressed L13 flashes 3 times very fast and flashes every 8-9 seconds. Is this ok for bootloader. But sketches issue is the same.

[sometimes it reject]

KuzGun,

I received your e-mail, but my answer returned because your mail adress is invalid (the @digitech.com.tr) [glow]sometimes it reject [/glow]

I hope that one of the adresses I've found is yours. (@MSN or @Orkut) [glow]mutlu_toker@msn.com is my adress[/glow]

The correct bootloader makes the onboard led L blink fast (less than half second), stop for almost 9 seconds, then blink again...[glow] i am not very familiar with this AVR thingies i am using AVRdude its write the bootloader and verify and says its ok [/glow]

Do you have the jumpers (auto reset - J4, and Serial On - J0) installed correctly on the board?[glow] Yes i am installed and using them.[/glow]

The different timming to reset (in case you don't use the auto reset feature) is the opposite:
First click the upload button.
After this, press the reset button on the board, with different delays.

Did you set your WinXP correct COM Port Speed to 19200?[glow] Yes in my case Com2 is my port and i changed the baudrate to 19200[/glow]

Alternatively, you can upload sketches directly to the chip without the bootloader:
Open the preferences.txt file in C:\Documents and Settings\UserName\Application Data\Arduino\preferences.txt;
Change the line uploading.using=[glow]bootloader[/glow] to
upload.using=[glow]parallel[/glow] (if you are using parallel port programmer);
Open Arduino IDE 0011;
Connect the board with Parallel Port Cable (not serial);
Upload sketch.[glow] i will try it.[/glow]
(reset button is not necessary).

Thanks for your helps.

Thanks for great job !
I have a couple questions i hope i am at the right place.

I made the S3V3 and burn a bootloader on Atmega8. When i power up the board. L13 flashes 8 times (is it correct boot up procedure) power led is on. But when send the sketches to the board TX led is on and RX led is blinking but i get the famous message

avrdude: stk500_getsync(): not in sync: resp=0x00
avrdude: stk500_disable(): protocol error, expect=0x14, resp=0x51

I am using 007 - 0010 and 0011 its nothing changes, here is the details ;

Windows XP Pro SP2
Using serial cable which connects 2-3-4-5 to 2-3-4-5
I am disabling the Zonealarm and Bitdefender
I try many different delay times like 2 scs. after reset 5 8 10 20 etc.

Any help will be appreciete.

Thanks for your helps and sorry for my bad english .

Hello i am new to Arduino i make an Adilson's serial Arduino with Atmega 8 mcu i am using the KS0108 library but i cant get any result in LCD. Did it work only Atmega168 board or not. If i try to upload sketch with LCD connected i get an error message. If i remove the LCD from the board it uploads the sketch but no result.

Thanks and sorry for my bad english .
