1  Using Arduino / Microcontrollers / Re: Optiboot 4.6 with atmega32 support on: June 23, 2013, 05:05:36 pm
I tried to build the Atmega32 and the Atmega88 (just to be sure) optiboot hex files. In both cases I get an error of the ID.exe program. This happens with the Arduino Windows version 1.0.5 under Win7 and WinXP.

This is the output on the screen

C:\Program Files\Arduino\hardware\arduino\bootloaders\optiboot>..\..\..\tools\avr\utils\bin\make OS=windows ENV=arduino atmega32
BAUD RATE CHECK: Desired: 115200, Real: 115200, UBRRL = 11, Error=0.0%
../../../tools/avr/bin/avr-gcc -g -Wall -Os -fno-inline-small-functions -fno-split-wide-types -mshort-calls -mmcu=atmega32 -DF_CPU=11059200L  -DBAUD_RATE=115200 -DLED_START_FLASHES=3      -Wl,--section-start=.text=0x7e00 -Wl,--section-start=.version=0x7ffe -Wl,--relax -nostartfiles -nostdlib -o optiboot_atmega32.elf optiboot.o
make: *** [optiboot_atmega32.elf] Error 1

I would appreciate your help. If somebody could compile me an Atmega32.hex file for 16Mhz Crystal without JTAG this would also be fine.

2  Using Arduino / Microcontrollers / How to get ATmega32(L) native USB support for programming? on: November 13, 2012, 12:08:48 pm
Hi everybody,
after browsing several boards and websites ( e.g. ) telling me how to successfully flash an ATMega32(L) board and use it as Arduino IDE compliant device, I'm still stuck with the need to program the board externally (JTAG, AVR-ISP, ...).
But in fact this ATMega32 board has a mircro USB connector, which is connected to PD0 (USB D-) and PD2 (USB D+).
Unfortunately my windows doesn't recognize the USB Device (ATMega board), when I connect it to my Windows7 x64.
The bootloader (e.g. ATmegaBOOT_168_atmega32.hex) with the blink-sketch "burnt" via ISP is working - the LED blinks.
Does anyone have an idea, if there is an ATMega32 "Arduino" bootloader, which natively supports the ATMega32-USB so I have programming and the serial port via the onboard USB connected to PD0 and PD2?
