JTAG Interface
Two JTAGs access to the TEBT0782 SoM are available through B2B connector JB3. JTAG access to the LCMXO2-1200HC System Controller CPLD is provided through B2B connector J3.
Pin J3-136 'JTAGENB' of B2B connector J3 is
...
used to access the JTAG interface of the SC CPLD. Set it high using DIP Switch S1-A in order to program the System Controller CPLD via JTAG interaface.
