Re: [Paparazzi-devel] Porblem with serial conecttor (Gareth Roberts, antoine drouin)

[Stephen L Hulme]

Dear Antoine

 

I compiled the ocaml library after invoking the O_UNBLOCK flag as per your original instructions.

 

I get a continuous red stream of "Unix.Unix_error(2,"read", "")" in the paparazzi centre console interspersed with

 

"File "pprz.ml, line362, characters 4-10:Assertion failed" in white after I click the execute button in the paparazzi centre.

 

It must be noted I get no build or upload errors.

 

I then did a "make clean make" command and the whole system just locks up.

 

I then removed the O_UNBLOCK flag and recompiled only to unfreeze the system but the gcs windows reappeared unpopulated. 

 

I have yet to retry adding the flag as it is getting late here. 

 

Regards   

 

Stephen

just to make sure, you recompiled the ocaml library after adding the
flag to open ?
