DFU mode on a beagleplay can be used via the Type-C connector by holding the USR switch while powering on.
Configuration is already provided as fragments for both the A53 and R5 u-boot parts. Include the am62x_a53_usbdfu.config config. The am62x_r5_usbdfu.config fragment needs to be added should DFU boot be required as this will disable booting from persistent storage due to binary size constraints.
