FELIX instructions for Petals
How to configure a petal (instructions taken from DESY repo https://gitlab.cern.ch/desy-atlas/itk/petal-testing):
cd into the petal-testing directory and then execute the following commands:
Setup the FELIX dependencies: source dependencies/setupFELIX.sh
Initialize the FLX card (it's normal if it says that all the channels are not aligned even if at least one actually is): flx-init
Invert the polarity (for lpGBTv1): flx-config set GBT_RXPOLARITY=0xFFFFFFFF
Verify the status of the PODs: flx-info POD
Check that all connected links are aligned: flx-info GBT
If testing the PPB R5 Vancouver Petal:
Configure the elinks on your FELIX card: source configs/elinks/elinks_petal_R5_640Mbs.sh
Check your config: elinkconfig Click on Read Cfg, then you can Quit
Push the lpGBT config to the petal chipset: fice -G0 -I71 configs/lpgbt/lpgbt_PT_M_LH_V1_Pri_hex.cnf
Verify this has worked (you should see the line "Compared 336 values, found 0 differences"): fice -G0 -I71 -C configs/lpgbt/lpgbt_PT_M_LH_V1_Pri_hex.cnf
Start FELIXCore and don't close this terminal: startFelixcore
In a second remote terminal session cd into the petal-testing directory and then execute the following commands:
Configure the YARR dependencies: source dependencies/setupYARR.sh
Activate the AMAC: write_amac_ppb 9 1 0 0
Confirm there is communication with the HCCs via a register dump scan: python3 scantools/run_YARR.py -c scanSetup_regDump.json --infile-dir scantools/configs_PPB_Vancouver_R5 twice (after the 2nd time, there shouldn't be lines like "There were no results for chip Stave_PPB_hcc1"
