Ramdisk image corrupt error while fusing

suchitasharma — Tue, 02 Feb 2021 06:53:26 GMT

We are using T1040 based board and trying to fuse linux,ramdisk and dtb images on the board. If we are tftping all the Images and boot from RAM then Images are booted successfully . But when we are tried fusing Images on NOR flash and booted using command "bootm e8020000 e9300000 e8800000", we are facing error:

## Loading init Ramdisk from Legacy Image at e9300000 ...
Image Name: rootfs.ext2.gz.uboot
Image Type: PowerPC Linux RAMDisk Image (gzip compressed)
Data Size: 33254400 Bytes = 31.7 MiB
Load Address: 00000000
Entry Point: 00000000
Verifying Checksum ... Bad Data CRC
Ramdisk image is corrupt or invalid

Kindly help us the resolve this issue.

Probably there is IFC timing configuration problem in u-boot, which causes problems to read/write NOR flash.

Please try the following test in u-boot on your target board.

=> mw.b 1000000 0xa5 10000

=> protect off all

=> erase e9300000 e931ffff
=> cp.b 1000000 e9300000 10000
=> cmp.b 1000000 e9300000 10000

For IFC timing configuration, you could refer to this document https://community.nxp.com/t5/Layerscape-Knowledge-Base/IFC-Controller-Configuration-on-QorIQ-Custom-Boards/ta-p/1109156
