You are quite correct. I had forgotten to setup the MXSBOOT_NAND_ARGS with the correct values for my flash. I had not considered this since the MfgTool had been able to flash the device with the .sb file. Since the .sb file is an input to the mxsboot command I figured it did not matter at this stage.

I have not been able to get U-Boot to write a bootloader using the .sb file like MfgTool does, however with the mxsboot parameters set I could flash the nand-file using the U-Boot script update_nand_firmware_full.

Many thanks for the help!
