Crystal oscillator input should be placed as close as possible to the AM263x or AM263Px XTAL_XI/XO with minimal length traces between crystal and MCU pads. A ground ring shorted to the local VSS plane should be placed adjacent and between the XTAL_XI and XTAL_XO traces to help prevent coupling from adjacent signals onto the clock higher impedance crystal input paths.
