Hi, I am trying to boot the kernel from SPI NOR. After doing tftp and writing the files, I am getting this error.

The checksum passes if I boot from the RAM with this environment:

bootdelay=3

baudrate=115200

ipaddr=192.168.1.103

serverip=192.168.1.101

netmask=255.255.255.0

rd_loadaddr=0x81000000

netdev=eth0

ethprime=FEC0

uboot=u-boot.bin

kernel=uImage

bootargs_base=setenv bootargs console=ttymxc0,115200

bootargs_spi=setenv bootargs ${bootargs} root=/dev/ram rw ramdisk_size=49000

But the board never stops executing(like in an infinite loop) these lines:

Hi,

I´d like to clarify, is u-boot executing with not issues? is the problem you have just related to the kernel booting process?

How are you flasing the SPI NOR? Do you just want to fetch the Kernel from SPI NOR? or even U-boot is located in SPI-NOR?

Regards,

Alejandro

Hi Alejandro,

Thank you for replying.

No issues with u-boot. At the u-boot prompt, I do the "tftp" and then "sf write" (to write into flash). After rebooting, I get the kernel checksum error.

I think the issue is with SPI NOR because everything works fine when I boot the kernel and fs from RAM.

Can you share all the commands you are using?
