USBaspLoader, need host driver for arduino

[xiao]

this is looking for help for following,


MCU : ATmega8, 12Mhz crystal
fireware :USBaspLoader.2008-02-05.zip
mega8_12mhz.hex
hfuse = 0xc0
lfuse = 0x9f


Two options were adopted to test this platform, the result is following,

---------------
a) by uses the driver of libusb-win32,

the device is recognized by the host as [ AVR USB device ],
ardinuno reports the following,

avrdude: invalid byte value (null) specified for immediate mode
avrdude: write to file 'null' failed

b) by uses the driver of USBasp,

the device is recognized by the host as [ USBasp ],

ardinuno reports the following,

avrdude: can not found the device VID = 0x16c0, PID = 0x05dc
---------------


due to the fact that we are not familiar with the arduino (version 0012), not sure how these host driver will work with the arduino.



further the step to test with ardunino with upload the LED blink example, the output by arduino as following. please advise how to deal with this metabroad vs the arduino is possible.

xiao,

If I understand you correctly, you have USBaspLoader installed on an AVR and you wish to upload a sketch to the chip from the Arduino. This would require a modification to the Arduino software to make it more flexible (allow bootloaders to use ports other than serial ports). Alternatively you could implement one of several dirty work-arounds. I'm currently working on finding the least dirty of them. I will post my findings.

Regards,
Chris
