I boot from MMC uboot, tftp MLO-am335x-evm, u-boot-am335x-evm.img, zImage-am335x-evm.bin, arago-tiny-image-am335x-evm.ubi and flash to NAND according to mtdparts partitions.
Then set uboot args
=> setenv nandargs 'setenv bootargs console=${console} ${optargs} root=${nandroot} rootfstype=${nandrootfstype}'
=> setenv bootcmd run nandboot
=> saveenv
But can't saveenv, . why save to FAT? seems it try to save to MMC.
Can boot from NAND with flashed uboot, but return same error when saveenv with booting from NAND Uboot.
Kernal,
I tried with PSDK 5.03, similar problem, saveenv default to MMC.
BTW, I can boot up with run nandboot. just can't saveenv to NAND.
Hello Tony,
To save the environment in a NAND device, please build a new U-Boot image by selecting these menuconfig options.
$ cd <Processor SDK>/
$ make u-boot_clean && make u-boot
$ cd board-support/u-boot-<version>/
$ ARCH=arm make menuconfig
Disable [ ] Environment is in a FAT filesystem and enable [*] Environment in a NAND device.
Environment ---> [ ] Environment is in a FAT filesystem
Environment ---> [*] Environment in a NAND device
Exit
Exit
Do you wish to save your new configuration?
< Yes >
$ cp .config configs/am335x_evm_defconfig
$ cd ../../
$ make u-boot_clean && make u-boot
Flash the board with the newly generated MLO and u-boot.img.
Best regards,
Kemal
Kemal,
with the Processor SDK6, I can't build the U-boot. no matter with the make command as you gave under root director of the PSDK, or export CROSS_COMPILE on command line, report the same error.
And I do it under Processor SDK 5.03, it is OK.
On Processor SDK5.03. the final step $ make u-boot_clean && make u-boot reports errors:
