Anyone implemented USBasp Loader inATMEGA32

Post by lxkarthi » Tue May 15, 2012 12:25 pm

I am trying to implement USBaspLoader in ATMEGA32.
When i plug in the USB, it says, device not recognised & shows as unknown device with both ids (vendor,device) as 00.
I used
PD6 as D-
PD2 as D+
PD1 as jumper.
Bootloader address as 7800 (configured in makefile)
Freq 16 MHz.
Fused High:d6 low:df
I am not locking ATMEGA lock bits (in order to save my chip if i program wrong lock bits)
I use Windows 7. & tried installing usbasploader driver for windows7.
Please, if anyone have already implemented it, HELP !

I have the same issue here with both atmega168p and atmega328p.

So I've switched to BootloadHID that seems to be working fine on my setup, but I really wanted to use USBAsp instead...

maybe you can try (

It is a recent patchlevel of the original USBaspLoader 2010-07-27 with a bunch of new feature and fixes.
(For example it is now possible to read FUSE and LOCKbits. Now, the bootloader also is enabled to be updated via its USB interface.)

If this won"t work I might patch this missing things into it...

Best regards,
