sorry for late

hello christian , i have two good news
1st the CDC driver for windows Vista is ready by Osamu Tamora and it's working 100% , i'd tested it on TOSHIBA Sattellite.
2nd i'd finished my new design on AVR Doper and i reduced it to half original size (skipped all HVSP component ) and i called it AVR minidoper . i'll try to put it in my homepage asap and i'll send u the premilary pics to tell me ur opinion and suggestions.

AVR-Doper [Rototron] programming problem

2008-04-29T10:42:57+02:00

USBasp is not compatible to any version of the STK500. It can therefore only be used with avrdude.

However, the USBasp hardware can run the latest version of the AVR-Doper firmware. With this firmware, it has most features of AVR-Doper and is thus compatible to the STK500v2.

SOLVED..

2008-04-29T05:39:47+02:00

thanks very much for helping me.
i recompiled it and it's working 100%.
another little question,can i use usbasp programmer as stk500? like avrdoper or it's only working on avrdude?

AVR-Doper [Rototron] programming problem

2008-04-27T16:36:43+02:00

Sorry about the LED, this is a bug with an #ifdef: The pin is configured as input and if on, the pull-up is enabled, providing a bit of current to the LED.

You can fix the problem by adding

Code:

    UTIL_PBIT_SET(ddr, HWPIN_LED);

in line 573 of file main.c (directly above UTIL_PBIT_CLR(port, HWPIN_LED); ).

I'll release a fix ASAP.

The CDC driver problem on Vista is not solved yet, as far as I know. Vista recognizes the device and it is listed, but it does not work. Any input on this topic is very welcome!

smal problem

2008-04-27T15:38:23+02:00

when i'd download the new firmware the program led is lighting very low
i think that because that is blinking in high frequency, i'll try to reduce it's R5 resistor.
about the new firmware, does it works on windows vista with both modes?
because i tried the earlier version and avr studio could not locate the port and avrdoper didn't work with libusb32.

AVR-Doper [Rototron] programming problem

2008-04-27T12:35:39+02:00

CDC mode speed can be limited due to aggressive polling by the host. The new version posted yesterday may bring an improvement here. Also, if you have a CPU clock of more than 1 MHz, you can try to pass -B1.1 to avrdude for a higher ISP clock. The -B option is stored in AVR-Doper until you override it or until the next reset.

When you build your own hardware, please have a look at http://www.obdev.at/goto.php?t=metaboard-prog

This hardware can run USBasp and the latest version of the AVR-Doper firmware with ISP only.

thank u very much

2008-04-27T12:18:31+02:00

thank u very much, the problem was that i vorget to put an external crystal, now it's 100% working in both CDC & HID modes
in CDC it's take 35 sec to read flash memory on atmega8 ,is that normal?
in HID mode it's fast.
here what i get in HID mode on avr doper after working:

avrdude -c stk500v2 -P avrdoper -p atmega8 -U flash:w:test2.hex:i -v -v

now i'm redisigning it in extra small size (all smd) and without hvsp ,can i put it on this site?
thanks alot.

AVR-Doper [Rototron] programming problem

2008-04-27T10:49:19+02:00

Please try to add a couple of -v options to the command line of avrdude. It should print more information about data sent and received.

Have you verified that the AVR you are programming is clocked with at least 1 MHz?

help

2008-04-27T01:50:26+02:00

hi there ,i have the same problem here
i build the same layout that is in the avrdoper folder ,i't connects to usb succesfully and when i select the programmer in avr studio (in cdc mode)
it's open but can't enter programming mode,also the led is blinking
i tried it on avrdude (in HID mode) the led is blinking but it 's failed either
here is what i get in avrdude:

(bin) 26 % avrdude -c stk500v2 -P avrdoper -p atmega8 -U flash:w:test2.hex:i

avrdude.EXE: stk500v2_command(): command failed
avrdude.EXE: initialization failed, rc=-1
Double check connections and try again, or use -F to override
this check.

avrdude.EXE done. Thank you.

i checked the voltage levels on the 74hc126 and the vcc was 4.8v if i use the usb supply and it's 5.1 when it's from external supply,i also checked the treset by connecting it to led's kathode and it's blinking the same as the programmer led.
so would u please help if u have any idea ,i build three copy's of the circuit's and tried many firmwares but it's same.
