Tips and tricks

Work with a particular FTDI device

1. Figure out serial number of desired device:

   djtgcfg enum
   Found 2 device(s)
   
   Device: HSDK
       Product Name:   DesignWare ARC SDP
       User Name:      HSDK
       Serial Number:  25164200001f
   
   Device: TE0604-03
       Product Name:   JTAG-ONB4
       User Name:      TE0604-03
       Serial Number:  251633000355
   

2. Specify FTDI serial number in the configuration script:

   diff --git a/tcl/board/snps_em_sk_v2.2.cfg b/tcl/board/snps_em_sk_v2.2.cfg
   index 6ebce71fa..df4455198 100644
