On the Ubuntu VM the lpc21isp was found but other errors came. I'm following the WIki exactly from this page:

It has been a very long time since I did this. Some things on the Wiki are likely assumed. Here's what I mean:
1. which UART? I'm going to assume the same one the XBee would use UART1 (same one lpc usb bootldr was uploaded from)
2. On the Wiki there is no mention of P0.14 having to be pulled low to enable the ISP mode. I will add it after verifying this in a few minutes. 

My initial attempt without pulling P0.14 low failed with "no answer on '?'" but I suspect that is expected. 

I suppose this is going to help many because as I read other ways to program they are not complete steps only generally how it's done. I mean someone could not literally follow step by step and be successful without extra information that's assumed the person would know. 

I'm curious, how would someone program over ISP using an XBee? More specific how would you pull P0.14 low remotely?

Hi Felix,

Such a simple answer. I like simple. I will try again on my Linux VM. 

If only it had said command not found vs file not found I would have figured that out.

Thank you.

Hi David,

Well, do you have lpc21isp installed?
It is not distributed with the paparazzi source code....

On debian/ubuntu this is provided by the lpc21isp package.
Looks like you are using OSX though... not sure if it's available there.

Cheers, Felix

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

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