AVR Doper

Post by cordless89 » Sat Jan 20, 2007 7:02 pm

Hello,

I recently built a AVR Doper and I am having problems writing to an AVR. I can read/verify the flash and even read the signature of the chip. But when I try to write the flash, I get an error.

STK500 command line programmer, v 2.2 Atmel Corp (C) 2004-2005.
Connected to STK500 V2 on port com3
Device parameters loaded
Programming mode entered
FLASH input file C:\test.hex read
Programming FLASH... Could not program FLASH
Programming mode left
Connection to STK500 V2 closed
WARNING! One or more operations failed! Please examine the output log above!


Entering programming mode.. OK!
Reading signature .. 0x1E, 0x93, 0x01 .. OK!
Signature matches selected device .. OK
Erasing device.. OK!
Leaving programming mode.. OK!

Reading FLASH input file.. OK
Entering programming mode.. OK!
Programming FLASH .. FAILED!
Leaving programming mode.. OK!


I can write to the AVR with Bascom and a simple parallel cable. But not a thing with the Doper. Any help is appreciated. BTW - Windows XP SP2

This may be due to the somewhat unreliable operation of bulk endpoints. Osamu Tamura maintains a list of hardware/operating system combinations which work or don't work with bulk endpoints. And he has some hints how to improve things. See his project at http://www.recursion.jp/avrcdc/.

Other than that I can recommend avrdude. If it fails, too, you can at least generate a debug log of the failure and maybe that helps debugging the problem.

If you can get a debug log from the STK500 command line programmer, too, please mail it to me.

Please forgive my novice attempts at this. I am not very proficient at this in the least but I am willing to try just about anything. I attempted the AVRDUDE but I was unable to to get a patched version that will work on XP to function. I will try avrdude if I can locate a complied version ready to go, as I am sure my capabilities don't go that far. As fas as the debug log, if you tell what to do to get this ready for you, I'll do that also. There has got to be some more in this hobby like me with out the knowlegde and knowhow... :oops: If you can assist me, I am willing. And I do appreciate everyone's help.

Thanks again.

If you use AVR-Doper in serial emulation mode, you should not need any patches for avrdude. A binary is included with WinAVR.

To get very verbose debug information with avrdude, use option "-v" multiple times. I don't know how debug info can be obtained from the STK500 command line programmer, though.

You can also get very verbose debug information from AVR-Doper itself (if compiled with debugging enabled), but that's a bit tedious because you need a level converter for RS232 and a terminal emulator.

I am really unsure as to the correct line parms for avrdoper but here it goes.

Same result. Any ideas now? I'm getting frustrated. :roll: Gotta be something simple I guess.

BTW - I can write to flash via the laptop but it fails verify everytime. But if I write and remove ribbon cable, the programmed AVR does it thing, (simple program to turn a pin on/off) but stops again after I re-plug it. I tried another PC and would write about 1 outa 25-30 tries. Hmmmmmm.

The relevant lines here are:
tk500v2_command(): unknown status 0x80
avrdud: stk500v2_paged_write: write command failed

Status code 0x80 means "command timed out".

Did you set the jumper for low speed programming ("Slow SCK" in circuit diagram)? This jumper currently reduces the ISP clock so much that programming an entire page can't be done within the timing limits.

If you need to program a device with 32 kHz crystal, please play around with the "-B" option to avrdude. There is an ISP clock which is slow enough to work with 32 kHz crystals but fast enough to avoid the timeout. But please remember: The -B setting is only used when the "Slow SCK" jumper is open.

The test circuit I am trying to program is a 8515 with a 10Mhz crystal. It programs fine with the simple parallel cable.

Any other ideas or things for me to try?

Thanks!

I'm not saying that the clock on your target device is too slow. It's the ISP clock which is probably too slow. You can configure the ISP clock either via the "-B" option to avrdude, through the STK500 programmer or simply with the "Slow SCK" jumper.

My first guess would be that you have set the jumper.

"Command timed out" means that the page or byte was not successfully programmed within the time interval specified by the programming software.

in HID mode with ISP jumper on:

C:\WinAVR\bin>avrdud -c stk500v2 -p 8515 -P avrdoper -u -U flash:w:test.hex

avrdud: AVR device initialized and ready to accept instructions

Reading | | 0% 0.00savrdud: a
vrdoper_send(): I/O Error.


And with -B option:

C:\WinAVR\bin>avrdud -c stk500v2 -p 8515 -P avrdoper -v -u -B flash:w:test.hex
avrdud: invalid bit clock period specified 'flash:w:test.hex'


Now what do you suggest? I'll try anything.

You can get usage information for avrdude with "avrdude -h".

Which jumper is the ISP jumper? You already reported that it worked in HID mode (at least reading). What's different now?

Please ensure that JP2 (Slow SCK) is open. If you have a scope, please also check that the ISP clock is reasonably high.

Basically it does the same, in or out of HID mode. Reads but no write. SlowSCK is open now. If I close that jumper, it programmer fails in HID mode.

I can read the AVR just fine, but it will not write. I do have a scope here but what pin is the ISP clock?

Thanks.

The ISP clock is pin 6 of the 74HC126 or pin 25 of the ATMega8. It will only toggle when the AVR is programmed or read.

My old Heathkit scope is about to die but the SCK line does go high during the attempts. Now what?
