OK, I tried another configuration file from the abatron site, and I am getting the same problem (see the file attached). Removing the workspace doesn't change anything. What seems curious to me, is : ">prog 0xFF900000 u-boot.bin Programming u-boot.bin , please wait .... # Programming flash memory failed at 0xff900002" I don't understand why asking for writing into 0xFF900000 it is trying to write into 0xFF980002... I tried different bus width too... JM _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
