Hello, I took the U-Boot version 1.3.2; now I am able to generate the make env -> fw_printenv utility.
I copy the jw_printenv binary and rename it to fw_setenv. I use the config file in the /etc directory. I want to access a NAND flash. [Pagesize = 0x800; ERASEBLOCKSIZE=0x20000] My uboot is in mtd1. mtd1 is from 0x20000 ... 0x100000 in my NAND-Flash The Uboot enviroment is from 0x60000...0x80000; the redundant from 0x80000...0x100000 My fw_config file is: /dev/mtd1 0x40000 0x20000 0x20000 /dev/mtd1 0x60000 0x20000 0x20000 Is this correct ? I am able tu use fw_printenv, the variables are printed on the console If I use fw_setenv I get errors: fw_setenv test 1 Unlocking Flash Done nand_write: attempting to write not page aligned data Erasing old enviroment Done Writing enviroment to /dev/mtd1: Invalid argument Error: can´t write fw_env to flash What´s wrong ????
