I'm using Sysconfig 1.11.0+2225 with mcu_plus_sdk_am64x_08_02_00_28. It is painfully slow, click on a button then wait 30 seconds or more. Behavior is the same on windows and linux. Correlation seems to be when the project has many GPIOs defined, as in the example examples/industrial_comms/iolink_master_demo/am64x-evm/r5fss0-0_freertos/example.syscfg
