Currently the bmode "usb" uses BOOT_CFG1 to 0x01, -which means BOOT_CFG1[7:4] is set to b0000. According to Table 8-7 Boot Device Selection this is NOR/OneNAND and not Reserved.
Use 0x10 which leads to b0001, which is a Reserved boot device. With that the SoC reliably falls back to the serial loader.
