Q: How do I reflash the system using TFTP?

Access Server does not boot up properly. I can't get to command prompt and I can't reflash it using WWW interface or USB memory dongle. Can I boot it up or reflash using TFTP to fix it?

A: Yes, in most cases you can use TFTP to fix it:

You can reflash the system using TFTP, if you can still get to bootloader prompt:
  1. Power on Access Server with terminal application connected to RS232 port
  2. Activate console with pressing b key in 5 seconds after the power on
  3. Press another key (not b) at Uboot boot to abort autoboot
    Hit any key to stop autoboot:0
