Dear friends,
I now had a look at the system where the V560 was running. It was also setup by Bastian. And there the code for the V560 module is slightly different from the one included in the NURDLIB branch that I am using on the test system.
Maybe you can have a look at it.
I also could push the complete NURDLIB from this system, if this helps.
Best greetings
Günter

Betreff: [subexp-daq] Report of a possible bug of the CAEN_V560 module
Dear friends,
I now grabbed a V560 module that was working fine in another DAQ system and put it into our test system.
The main.cfg looks like this:
log_level=spam # info, verbose, debug, spam
CRATE("MCAL") {
GSI_VULOM(0x03000000) {
timestamp = true # needed to get timestamps in the data output
# ecl=0..15
}
BARRIER
CAEN_V560(0x333333300) {
use_veto = true
}
# CAEN_V767A(0x03100000) {
# }
}
Starting the DAQ now results in a freeze of the RIO4. A reset of the crate is necessary to talk to it again.
The problem occurs in the first slow init of the V560 module. To find the exact line, I added some output to CRATE.C:
10: crate/crate.c:923: .Slow-init module[0]=GSI_VULOM.
before push_log_level(module)
before a_crate->module_init_id = module->id
before module->props->init_slow(a_crate, module)
LOG: TRLO: MD5SUM: 0x1409285e (CT: 63bb1d44 = 2023-01-08 19:45:08 UTC)
before module_init_id_mark(a_crate, module)
before pop_log_level(module)
10: crate/crate.c:923: .Slow-init module[1]=CAEN_V560.
before push_log_level(module)
before a_crate->module_init_id = module->id
before module->props->init_slow(a_crate, module)
The CRATE.C code now looks like this:
TAILQ_FOREACH(module, &a_crate->module_list, next) {
if (NULL == module->props) {
continue;
}
LOGF(info)(LOGL, "Slow-init module[%u]=%s.", module->id,
keyword_get_string(module->type));
printf("before push_log_level(module) \n");
push_log_level(module);
printf("before a_crate->module_init_id = module->id \n");
a_crate->module_init_id = module->id;
printf("before module->props->init_slow(a_crate, module) \n");
if (!module->props->init_slow(a_crate, module)) {
printf("before pop_log_level(module) \n");
pop_log_level(module);
printf("before goto crate_init_done \n");
goto crate_init_done;
}
printf("before module_init_id_mark(a_crate, module) \n");
module_init_id_mark(a_crate, module);
printf("before pop_log_level(module) \n");
pop_log_level(module);
}
Thus, to me it looks like the check "if (!module->props->init_slow(a_crate, module)) ..." is doing something quite horrible to the RIO4.
This is unfortunate, because my original aim was to show that there is also a bug/mistake in readout_dt of the V560 module. But I did not come this far.
Do you have any idea what might cause the freezing of the RIO4?
Best greetings and many thanks
Günter
