Just a guess: You are using imx_nand_load_image() with a fixed size of 256k. grep for this function in the current tree and see how the correct image size is calculated.

Good point. In any case the driver isn't able to recognize your nand device. I see from you supplied code snipplets, that your barebox is at least two weeks old. Maybe you use the upstream tree, as maybe there are already fixes for imx53 nand flash. Also you may want to activate mtd debugging: #define CONFIG_MTD_DEBUG #define CONFIG_MTD_DEBUG_VERBOSE 3 for example to your include/linux/mtd/mtd.h file. (Those are config settings, but they don't appear in any Kconfig file, hence supply them manually) good luck. > > >> I flashed from 0x0 to 0x7FFFF (image size: 479K). >> I flashed the environment image (image size: 3K) from 0x80000 to 0xFFFFF >> and changed the config code from barebox/environs/common/config to: >> >> ... >> nand_parts="512k(barebox)ro,768k(bareboxenv),4M(kernel),120M(root)" >> ... >> >> Barebox can boot now but the startup log says: >> barebox 2012.03.0-dirty (Jul 16 2012 - 09:01:01) >> >> Board: i.MX53 >> eth@eth0: got MAC address from EEPROM: ********************* >> nand_get_flash_type: second ID read did not match ef,ef against c0,c0 >> No NAND device found (-19)! >> Malloc space: 0x7df00000 -> 0x7fefffff (size 32 MB) >> Stack space : 0x7def8000 -> 0x7df00000 (size 32 kB) >> Open /dev/env0 No such file or directory >> running /env/bin/init... >> not found >> barebox:/ >> >> How can i get the environment loaded? > > Normally you would issue 'saveenv' which writes the environment to the > environment partition.

Good point. In any case the driver isn't able to recognize your nand device. I see from you supplied code snipplets, that your barebox is at least two weeks old. Maybe you use the upstream tree, as maybe there are already fixes for imx53 nand flash. Also you may want to activate mtd debugging: #define CONFIG_MTD_DEBUG #define CONFIG_MTD_DEBUG_VERBOSE 3 for example to your include/linux/mtd/mtd.h file. (Those are config settings, but they don't appear in any Kconfig file, hence supply them manually) good luck. > > >> I flashed from 0x0 to 0x7FFFF (image size: 479K). >> I flashed the environment image (image size: 3K) from 0x80000 to 0xFFFFF >> and changed the config code from barebox/environs/common/config to: >> >> ... >> nand_parts="512k(barebox)ro,768k(bareboxenv),4M(kernel),120M(root)" >> ... >> >> Barebox can boot now but the startup log says: >> barebox 2012.03.0-dirty (Jul 16 2012 - 09:01:01) >> >> Board: i.MX53 >> eth@eth0: got MAC address from EEPROM: ********************* >> nand_get_flash_type: second ID read did not match ef,ef against c0,c0 >> No NAND device found (-19)! >> Malloc space: 0x7df00000 -> 0x7fefffff (size 32 MB) >> Stack space : 0x7def8000 -> 0x7df00000 (size 32 kB) >> Open /dev/env0 No such file or directory >> running /env/bin/init... >> not found >> barebox:/ >> >> How can i get the environment loaded? > > Normally you would issue 'saveenv' which writes the environment to the > environment partition.
