I've a T4240QDS-PB board and experienced an unexpected operation which corrupt RCW&U-boot from the onboard NOR Flash, I brick it. During the past time, I tried to restore the images lost for NOR flash but it didn't work. I have two debuggers: USBTAP and lauterbach PowerDebug USB 3, which I supposed could be used to flash images.
My question is does anyone experience such issue and instructs me how to restore it? Much appreciate!!
