Hi,
I'm using the 'Solar Inverter HV AC-DC EVM' with a Concerto Control Board. I follow the instruction outlined in ''QSG_HV_Solar_Inverter_System_GUI_Rev1.2.pdf' shown below...
In my case LD3 flashes (not LD2). Do you know what this indicates and if it is a problem?
Set up the DC-AC Inverter EVM and the Load
The DC-AC Inverter can be controlled either by a Piccolo (CC2803x) control card or a Concerto
(CCF28M35xx) control card. For jumper and switch configuration related to each of these control
cards please refer to the DC-AC Inverter EVM quick start guide. Select the desired control card and
connect it to the 100pin header U2 on the Inverter EVM.
Now connect USB connector to the control card on the DC-AC Inverter EVM. Use the ribbon cable to
connect the 10-pin header CN5 on the Inverter EVM to the other 10-pin header H2 on the DC-DC
EVM. Ensure that the ribbon cable is installed properly so that all 10 pins on both headers are
connected one to one (pin 1 on CN5 connects to pin 1 of H2 and so on). Use an external +15Vdc
supply at J1 to power up, for now, all the control circuits on the DC-AC Inverter EVM. By default, the
controller (Piccolo or Concerto) is enabled to boot from FLASH and run the HV Solar DC-AC Inverter
code. Turn on the switch S1 by placing it away from J1 and towards the 10-pin header CN5. This will
apply the external +15Vdc supply to the DC-AC Inverter EVM. Check the led LD2 on the control
card. If the LED is flashes in every 1 second then continue to do the next steps. Otherwise,
check the auxiliary power, the control card jumper configuration for boot from flash, or reload
the program. Also, at this point the led LD2 on the DC-DC EVM should start flashing
indicating the communication between the two EVMs. If this does not happen then check the
ribbon cable connection between the two EVMs.
