[Paparazzi-devel] ISP programming question

[PPZUAV]

Hello,

I am trying to program a NavGoV3 with ISP programming. I use this command:
lpc21isp   /Users/bmw330i/paparazzi-software/var/NAVGOv3/ap/ap.hex /dev/ttyS0 
38400 12000
make[1]: lpc21isp: No such file or directory
make[1]: *** [upload] Error 1
make: *** [ap.upload] Error 2

lpc21isp not found? 

My version: 
quadzilla:paparazzi-software bmw330i$ ./paparazzi_version 
v4.0.3_stable-2-gdeebbe3-dirty

Is it no longer possible to program via serial over UART?
