according to Pippo, in order to start a readout with more than 12 links one needs to use both DMA endpoints. Are there some instructions on how to do this? I would assume the following:
- start the roc-bench-dma for each end-point
- adapt the tpc-readout-test.py script
For the later point, can i specify simply the link =[0,1,2,3,4,5,6,7,8,9,10,11,12,13]? Or do i need to copy the following part and adapt it for the second endpoint:
#enable selected links links=[0,1,2,3,4,5,6,7,8,9,10,11] #links= for l in links: cru.dwrapper.linkEnableBit(l) cru.dwrapper.setGbtDatapathLink(wrap=0,link=l,is_GBT_pkt=0,RAWBYLEN=1,RAWBYID=0,RAWMAXLEN=0x1EA) cru.dwrapper.packetmuxPadLen(arbmode=0) cru.dwrapper.setFlowControl(wrap=0,allowReject=0,forceReject=0)
The code looks like one needs to do this for each data path wrapper.
