Sure. MPC8349EMDS eval board here. It fails to boot, giving the following output. U-Boot 2009.06-00525-gf33b325 (Jul 24 2009 - 09:34:25) MPC83XX Reset Status: Software Hard, External/Internal Soft, External/Internal Hard CPU: e300c1, MPC8349EA, Rev: 3.0 at 528 MHz, CSB: 264 MHz Board: Freescale MPC8349EMDS I2C: ready SPI: ready DRAM: 256 MB (DDR1, 64-bit, ECC off, 264 MHz) FLASH: ## Unknown FLASH on Bank 1 - Size = 0x00000000 = 0 MB *** failed *** ### ERROR ### Please RESET the board ### Thanks, Ira _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
