Booting kernel and filesystem in p1022 based board from spi flash

somyaaggarwal08 — Tue, 28 Mar 2017 11:22:10 GMT

Hi,

I am able to program and load uboot from spi flash. I want to boot kernel , device tree and file system also from spi flash.

I have programmed all the above required files in spi flash .Using sf read commands , I have copied kernel and device tree from spi flash to ram and run bootm command.However i get the error " Verifying Checksum ... Bad Data CRC
ERROR: can't get kernel image!". Can anyone suggest something to resolve this issue.

Please find below the error log:

Hi,

I am getting the same error when in try to boot kernel from spi flash in the eval board also. I am using the uImage (uImage--3.12-r0-p1022ds-20161214044917.bin ) generated by bitbake fsl-image-full. Is this the uimage for spi flash also??

Test your board using command sequence like to command sequence from the Section 4.4.9.6.1 of the SDK 1.9 Documentation:

Booting Up the System

Execute the following commands to TFTP the images to the board, then boot into Linux.

=>tftp 1000000 <uImage_name>

=>tftp 5000000 fsl-image-core-<platform>.ext2.gz.u-boot

=>tftp 2000000 <platform_dtb_name>

=>bootm 1000000 5000000 2000000

Is there problem if this command sequence is used?

Test your board is similar command sequence is used for booting from SPI.

Read uImage:

sf read 0x1000000 0xa0000 4136b0

Read platform dtb file

sf read 2000000 0x4c0000 0x3c28

Add command for reading your file system.

Have a great day,
