"After flash process, board turn down, but it's still old image."
BBGW will boot from eMMC by default. "to boot from MicroSD press the User Button(S2) While applying power" This is important but ambiguous. The button to push is the BOOT button near the Grove connectors and the antennas. You must hold down BOOT, then remove USB power then re-insert USB power then release BOOT button. BBGW System Reference Manual has the details: A switch is provided to allow switching between the modes. Holding the boot switch down during a removal and reapplication of power without a microSD card inserted will force the boot source to be the USB port and if nothing is detected on the USB client port, it will go to the serial port for download. Without holding the switch, the board will boot try to boot from the eMMC. If it is empty, then it will try booting from the microSD slot, followed by the serial port, and then the USB port. If you hold the boot switch down during the removal and reapplication of power to the board, and you have a microSD card inserted with a bootable image, the board will boot from the microSD card. NOTE: Pressing the RESET button on the board will NOT result in a change of the boot mode. You MUST remove power and reapply power to change the boot mode. The boot pins are sampled during power on reset from the PMIC to the processor. The reset button on the board is a warm reset only and will not force a boot mode change.
