I'm recollecting bug information you pointed, please correct what I'm saying here. Current tree for AT45DB041D part has configured flash->erase_cmd = CMD_ERASE_4K; flash->erase_size = 4096; The same configuration is not working for your board, is that true? Did you see working tree in earlier tag releases? -- Jagan. _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
