Hello,
I am using am335x evm with its available am335x-evm.dtb, zImage , MLO and u-boot.img.
I am using
kernel : 4.1
sdk : ti-processor-sdk-linux-am335x-evm-02.00.00.00
for file system i use buildroot-2015.05.
In menuconfig of buildroot-2015.05, i have changed toolchain path, kernel header version and ubifs parameter
i am using toolchain available with ti-processor-sdk-linux-am335x-evm-01.00.00.00
Kernel Header: 3.14
I have set
logical eraseblock size = 0x1f00
minimum I/O unit size = 0x800
maximum logical eraseblock count = 392 ( Calculated by considering 50MB partition for file system)
physical eraseblock size = 0x20000
sub-page size = 512
Additional ubinize options = -O 0x800
By using above configurations i have created rootfs.ubi.
After that all images zImage, u-boot,.img , MLO , am335x-evm.dtb and rootfs.ubi are being stored in sd card and during booting i have written into nand.
But when i boot evm using nand i got error below:
U-Boot SPL 2015.07-00114-gf5078ef-dirty (Dec 22 2015 - 23:18:40)
The Expected Linux image was not found. Please check your NAND configuration.
Trying to start u-boot now...
