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

Enable links

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!

Set SuperChunk factors per link

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
