Other Parts Discussed in Thread: AM3358

I have using a AM3358 EVM and the ti-processor-sdk-linux-am335x-evm-01.00.00.03.

In order to enhance boot speed, SPL OS BOOT Mode want to use.

My boot mode is a NAND boot mode.

I make uImage and write to NAND, so SPL OS Boot mode is entered

But The kernel failed to boot. No message.

Kernel imag and am335x-evm.dtb is OK reading from nand.

Please help me.

Hi,

Please add #define DEBUG at the beginning of common/board_r.c & common/board_f.c files to get some output out of the boot process.
This way you can get some more information about where u-boot gets stuck.

Best Regards,

Thank you for your interest in.

I solved the problem after change CONFIG_CMDLINE="root=/dev/mmcblk0p2 rootwait console=tty02,115200" to CONFIG_CMDLINE="root=ubi0:rootfs rw ubi.mtd=NAND.file-system,2048 rootfstype=ubifs rootwait=1 console=ttyO0,115200" in tisdk_am335x-evm_defconfig file.
