Title: Success: using v3c as AVR programmer
Post by: emusic on August 26, 2014, 05:43:17 pm

Got success working with ATMega8 under 64-bit Windows 7.

Hardware:

Bus Blaster v3c.
Self-made 20-to-10 pin cable.
USBASP 2.0 board with SP2 self-programming jumper soldered and closed.

Software:

FTDI 2.10.00 driver pack installed.
Buffer logic programmed with BBV3-JTAGkey-selftest-v1.1.svf file.
libusb 1.2.6.0 installed, FT2232 Serial Converter A replaced by libusb device (using inf-wizard).
avrdude 5.11-Patch7610 installed.

With "-c 2232HIO", avrdude successfully recognizes, reads and writes ATMega8 on USBASP board.

Unfortunately, avrdude (and flashrom) does not recognize BB if interface A is not converted to libusb device with inf-wizard. avrdude 6.x Win32 binaries have no avrftdi/libusb support so I cannot test them.

To revert back to Serial Converter A, just delete libusb device in Device Manager (don't check "Delete the driver software") and rescan the hardware (or re-plug BB).
