hallo, 

i hope someone can help me whit the problem i have.

AS 7.0.1931

dragon

 

ISP & JTAG (incl. debugging) is working fine on a Atmega16 and Atmega32.

but is not working on a Atmega1284P

 

when i want to read the device signature (with ISP), i got the error:

Failed to enter programming mode. ispEnterProgMode: Error status received: Got 0xc0, expected 0x00 (Command has failed to execute on the tool)

 

thanks in advance.

Please show us a pic of your setup, does the chip have power on all vcc + avcc / gnd pins?

Is the 1284P a brand new chip?

 

Has it perhaps been used before and set for an external crystal? Do you have a crystal attached?

#1 Hardware Problem? https://www.avrfreaks.net/forum/...

#2 Hardware Problem? Read AVR042.

#3 All grounds are not created equal

#4 Have you proved your chip is running at xxMHz?

yes its brand new, and i don't have an extern Xtal. because its not working on ISP & JTAG i can not check or the fuses is set on intern Xtal.

but when its new i think the fuses is standing on intern Xtal, is that wright ?

Correct (nearly). A new chip should be running on the internal RC oscillator at 1MHz.

 

Thinking about it....what programming speed is your tool set to? Have you tried slowing it down?

ISP is 125 khz and the JTAG is 200 khz.

i try to slow it down but still not working.

 

is it possible that i need new software in the dragon, because the dragon is maybe 8-10 years old ? maybe there was no Atmega1284 in that time.

i just read that when de software in the dragon is not wright, AS7 will come automatically whit a massage to update the software. 

i also can't read the target voltage.

That sounds like it is not wired correctly, or no power is applied.

Again I'll ask to see a picture of the setup, else I can not help.

not sure but very limited internet connection at the moment so can not check.

But does the Mega1284 not have its programming interface on other pins compared to the Mega16/32 ?
