Onboard bl702 came with the cklink firmware instead of dual uart firmware

• https://github.com/bouffalolab/bl_mcu_sdk/blob/master/tools/dualuart_firmware/bl702_dualuart_whole_img.bin
• pip install bflb-mcu-tool
• hold boot while plugging in to the "uart" usb port
• bflb-mcu-tool --chipname=bl702 --firmware=bl702_dualuart_whole_img.bin
• power cycle board
• default firmware can be seen running on the first usb uart, bootloader on the second, both at 2000000 buad
