So, I resolved my problem

It turned out that my USB port gives to small current (probably 100-200 mA for unregistered devices such as my programmer - my device takes more than 200 mA) or the USB voltage is to small (4,79V). I changed programmer jumper and now programmer is supplied from programmed device (which is powered by 5V), and all problems gone

One post higher i wrote that read of eeprom and flash was OK - it wasn't. Programming my RC radio with this read-before software gives many "$#$#@$>.

Hi!

I have the same problem.
I use Windows 7 and XP, avrdude, STK500v2 (avrdoper port), device is Atmega64.

I get the same problem

Writing | avrdude.exe: stk500v2_command(): unknown status 0x80
avrdude.exe: stk500v2_paged_write: write command failed
################################################## | 100% 0.21s

avrdude.exe: failed to write flash memory, rc=-1

I can successfuly read fuses, eeprom, signature, flash, but i have this error while trying to write flash.
I tried to program device in HID mode (Windows 7) and HID and COM (Windows XP) - in both i have the same error.

I can program atmega32 (internal clock 1MHz) without any problem. Mega64 works with 16MHz crytal. This atmega64 is cpu of Turnigy 9x, RC transmitter (http://unitedhobbies.com/hobbyking/stor ... ady-01.jpg).

The voltage of my USB is ~ 4,79V. I connect my STK directly to motherboard USB port (notebook).

Do you know what can be wrong?

It's not a question of USB 1 or 2, it's a question of the chipset. Some USB chipsets accept voltages outside the specified range, others don't. Older chipsets accept 5 V levels on D+ and D-, most newer chipsets get outside their common mode range.

AVR-Doper does not support AT89 chips. Don't know whether your source has modified the code, though.

it is works with computer with USB 1.1, not work at computer with USB 2.0, but if connect to computer with USB 2.0 thru the USB 1.1 hub - ist work.
With USB 1.1 - work, with USB 2.0 not work. But USB 2.0 is backward compatible with USB 1.1 and devices with USB 1.1 must works with USB 2.0 ports.

Hi! Sorry for bad english

Thanx for AVR-Doper! I was buy the board with components and preprogrammed ATMega8 - http://icdarom.ru/show_good.php?idtov=2130723908.
And I think its based on AVR-Doper project. The scheme is identical, but added 20-, 28-, and 40-pin sockets.

When I make the device and connect it to PC with USB 2.0 Windows see it as Unknown Device and can't install the driver. But when connect to old PC with USB 1.1 all works OK. If I connect to PC with USB 2.0 throu the 4-port USB 1.1. HUB it's too works OK. I think AVR-Doper have a bug - when it receive USB 2.0 packet it work uncorrect. But other USB 1.1 devices (USB-keyboard, mouse, joystick, mobile phone) works OK with USB 2.0 port.

And i have a question - how i can program the AT89C4051 controller? Or information about supported chips here - http://icdarom.ru/show_good.php?idtov=2130723908 is incorrect and AVR-Doper can't burn conrollers like AT89C4051 - without SPI interface?

This must be a problem with the programming algorithm. I don't have a mega16 for testing, though. Has anybody else seen this problem?

Hi all.

I've got the same problem.

My command line is:
avrdude.exe -c stk500v2 -P com4 -p m16 -e -v -U flash:w:"S:\cerebro.hex":i -B 10

I got the same timeout (0x80) problem. I'm using 5V VCC.

The interesting is that I can read the flash into a file and also read/write the eeprom!

Only the flash write fails

All seems to be okay now as I can successfully used avrdude serial & hid modes. Avrstudio is also now working via pc usb port. I really appreciate all your time and effort in this project as well as putting up with me.

Once again, thank you.

OK, thanks for the valuable input! I have found a bug in the ISP code when doing "value polling". This mode is used for older devices such as the AT90S8515.

We will release a new version soon which fixes this firmware bug.

[This still does not explain why connecting through a hub makes a difference, though.]
