HairyDairyMaid with few minor modifications shoul be able to flash your device, most likely you will have to tell it which CPU and Flash you have. Since HairyDairyMaid already supports BCM6348 which is very very similar to BCM6358 you should be able to use the same tricks. Alternatively you can use urjtag (SVN version) which has support for it. -- Best regards, Florian Fainelli Email : [email protected] http://openwrt.org -------------------------------
