Programming 3v3 atmega328p on gertboard

hi,

i'm trying program atmega328p on gertboard connected raspberry pi via arduino since spi interface in use.  have uno board arduinioisp installed output pins level shifted 3v3.  have included new definition in boards.txt

gert328.name=gertboard atmega328 (w/ arduino isp)
gert328.upload.using=arduino:arduinoisp
gert328.upload.protocol=arduino
gert328.upload.maximum_size=32768
gert328.upload.speed=115200
gert328.upload.disable_flushing=true
gert328.bootloader.low_fuses=0xe7
gert328.bootloader.high_fuses=0xda
gert328.bootloader.extended_fuses=0x05
gert328.bootloader.path=optiboot
gert328.bootloader.file=optiboot_atmega328.hex
gert328.bootloader.unlock_bits=0x3f
gert328.bootloader.lock_bits=0x0f
gert328.build.mcu=atmega328p
gert328.build.f_cpu=12000000l
gert328.build.core=arduino
gert328.build.variant=standard

the programmer set arduino isp on ide on laptop connected uno via usb , try an" upload using programmer"
ans following output when trying upload blink:

binary sketch size: 1,104 bytes (of 32,768 byte maximum)
avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0xc2
avrdude: stk500_getsync() attempt 2 of 10: not in sync: resp=0xc2
avrdude: stk500_getsync() attempt 3 of 10: not in sync: resp=0xc2
avrdude: stk500_getsync() attempt 4 of 10: not in sync: resp=0xc2
avrdude: stk500_getsync() attempt 5 of 10: not in sync: resp=0xc2
avrdude: stk500_getsync() attempt 6 of 10: not in sync: resp=0xc2
avrdude: stk500_getsync() attempt 7 of 10: not in sync: resp=0xc2
avrdude: stk500_getsync() attempt 8 of 10: not in sync: resp=0xc2
avrdude: stk500_getsync() attempt 9 of 10: not in sync: resp=0xc2
avrdude: stk500_getsync() attempt 10 of 10: not in sync: resp=0xc2

i'm not sure doing wrong , grateful pointers.

cheers
