We use the Phytec LPC3250 on a costum board based on "phy3250 development kit", with a Flash NAND.
We have never experienced any problems until we used u-boot 1.3.3. But since we have tried to install the latest u-boot 2009.03, we are not able to load Linux kernel.
Note that the uboot package is correctly patched with NXP patch.
The error is as follow:
------------------------------------------
NAND read: device 0 offset 0x190000, size 0x175e00
1531392 bytes read: OK
## Booting kernel from Legacy Image at 80100000 ...
Image Name: Linux-2.6.27.8
Image Type: ARM Linux Kernel Image (uncompressed)
Data Size: 1526636 Bytes = 1.5 MB
Load Address: 80008000
Entry Point: 80008000
[color=#f00]Verifying Checksum ... Bad Data CRC
ERROR: can't get kernel image![/color]
---------------------------------------------
These are the checksums, shown by "printf" added to the code:
--------------------------------------------
crc calculated: 9e3b506f
crc uimage: 4b7cfc6d
hdr: 83f4fb20
--------------------------------------------
By uboot 1.3.3 the crc calculated was 4b7cfc6d, the same as the crc uimage.
The uImage file is the same as the one that has been used to date (Linux-kernel 2.6.27.8) so we are thinking of setting the same environment parameters.
I checked that machine id is correct.
My printenv is:
----------------------------------------------
setenv bootfile uImage
setenv bootcmd 'nand read 0x80100000 190000 0x175e00; bootm'
setenv fileaddr 0x80100000
setenv loadaddr 0x80100000
setenv bootargs console=ttyS0,115200n81 ubi.mtd=3,512 root=ubi0:rootfs rootfstype=ubifs reboot=soft lpj=207360 quiet init=/sbin/init
----------------------------------------------
We can't find the reason why the crc calculation returns this error.
Could you give us some advice?
I hope you can help us.
If it's necessary, we can give you more details and information.
Best regards.
