Если RedBoot жив, то можно.. Я думаю хозяева форума вскорости файлики для заливки и доки выложат в FAQ..
TFTP UPGRADE
In the following cases, upgrade the s/w image of the AP on the bootloader by using the SIO cable.
When the AP cannot be booted normally
When upgrading by using the web it is not possible
The method of upgrading is as follows.
1) Preparation: PC (TFTP server), LAN cable, SIO cable
2) Save the s/w image of the AP in the PC. The required image files are zImage and jffs2.image.
3) Execute the TFTP server and set the directory where the above two files are saved as the server directory.
4) Connect the SIO port of the AP and the com port of the PC with the SIO cable.
5) Connect the LAN port of the AP and the Ethernet port of the PC with the LAN cable. It should be connected to the LAN port other than the WAN port of the AP by all means.
6) Execute the HyperTerminal program of the PC and set it to be connected to the com port.
The Baud Rate of the AP is 115200.
7) Turn on the power of the AP and check if the booting message appears on the hyper-terminal window.
8 ) Press Ctrl+C during booting to move to the Redboot> status.
