TMS320F28388D: EtherCAT DC Sync0 mode

TMS320F28388D: CPU1 or CM Loopback Example Code: Map Sync0 Signal to GPIO127

Hi experts,

Is anything extra required to enable and map the ESC sync0 signal to pins 127? After reading through the code it looks like it should already be mapped and the GPIO is set up for this. However I have an EtherCAT system set up with this device and DC is enabled. I don't see any toggling at all on pins 127 and 128. I get reports from the EtherCAT mainDevice that DC is on and applies correction values. Using the C2000ware SDK and the CPU1 loopback example with no modifications.

Best,
Seth
