You can do this either using the felix UPS product in the dune-daq software or a custom build of the felix software suite provided by ATLAS TDAQ.
To use the UPS product, you can use these tools where you did run:
dbt-workarea-env
In order to enable links, the corresponding registers need to be set: DECODING_LINK00_EGROUP0_CTRL_EPATH_ENA, where LINK marks the link identifier. In order to enable the 10 links on the card (5-5 on the 2 SLRs), do this:
echo Disabling every link on SLR 0...
for i in {00..11}; do flx-config -d 0 set DECODING_LINK${i}_EGROUP0_CTRL_EPATH_ENA=0; done;
echo Disabling every link on SLR 1...
for i in {00..11}; do flx-config -d 1 set DECODING_LINK${i}_EGROUP0_CTRL_EPATH_ENA=0; done;
echo Enable 5-5 links on the 2 SLRs
for i in {00..04}; do flx-config -d 0 set DECODING_LINK${i}_EGROUP0_CTRL_EPATH_ENA=1; done;
for i in {00..04}; do flx-config -d 1 set DECODING_LINK${i}_EGROUP0_CTRL_EPATH_ENA=1; done;
If two cards are installed in the host, repeat those operations also using the commandline options -d2 and -d3!
Be careful, as these register are SuperLogic Region (SLR) based! To change the register values for factor 12, for both SLRs' first 10 virtual links, run the following:
for i in {00 11}; do flx-config -d 0 set SUPER_CHUNK_FACTOR_LINK_${i}=0x0c; done;
for i in {00 11}; do flx-config -d 1 set SUPER_CHUNK_FACTOR_LINK_${i}=0x0c; done;
If two cards are installed in the host, repeat those operations also using the commandline options -d2 and -d3!
and then rerun flx-config -d (0...3) list | grep SUPER to check all the values changed. The superchunk factor is changed to 0x0c as the readout software is prepared to receive chunks with an aggregation factor of 12:
0x2de0 [RW 07:00] SUPER_CHUNK_FACTOR_LINK_00 0x0c number of chunks glued together
0x2df0 [RW 07:00] SUPER_CHUNK_FACTOR_LINK_01 0x0c number of chunks glued together
