librp.so fails to init

[ralu]

linking against librp.so

code

Code: Select all

#include "rp.h"
#include "stdio.h"

int main(){
    printf("vesrion %s\n",rp_GetVersion());
    int v = rp_Init();
    printf("%d\n",v);
    for(int i=RP_LED0;i<RP_LED7 ;++i){
        int r = rp_DpinSetState(RP_LED0, i%2);
        printf("%d\n",r);
    }
    return 0;
}

outputs

Code: Select all

vesrion 0.93-14 (f0b30fc)

and then it freeze. Calling rp_Reset and just seeting pins yields Segementaion error.

i have same lib on both sides with md5sum 2d8825845b4abcc0f1aa088899de8b81

Is there any simple hello world using librp.so available?

i have also build and executed https://github.com/RedPitaya/RedPitaya/ ... nk_diode.c ,

here is output

Which compiler are you using?

Cheers, Luka.

I later figured out what is going on. Issue is with some initialisation. I had to manually reboot RP for make it work. I am now playing with cross-ghc (haskell compiler for arm) but due to lack of source code I am unable to debug librp. It is working somehow fine (first time only) altough it takes like 30s to init. How can I debug issue with init?
