Thanks Don for the suggestions.
I tried different flavours:
1- relative delays: start after (what I believe to be) late services
After=syslog.target network.target
2- absolute delays:
ExecStartPre=/bin/sleep 60
TimeoutSec=100s
3- including large delays inside C.
None worked. It's like it is not linked to the timing itself...
*Could some access grant stuff be defined at the time the service is
scheduled, rather than at the time the service actually starts ?*
Or maybe, I do something wrong in my C code ? not adequate at boot up ?
Here is an example.
fd_len = snprintf(buf, sizeof(buf), "%s/period",
"/sys/devices/ocp.3/pwm_test_P9_14.16");
fd = open(buf, O_WRONLY);
if (fd < 0) {
perror("pwm/period");
printf("pwm/period, %s", buf);
return fd;
}
Additional help would be much appreciated :-)
