Re: [Ltib] Kernel panic after update the latest source for LPC32xx target

[Li Yuan-Lung]

Dear all,

Finally I found where the problem is.

The mem-map changed in MTD block!

The old one is:

Creating 4 MTD partitions on "lpc32xx_nand":

0x000000000000-0x000000168000 : "phy3250-boot"

0x000000168000-0x000000190000 : "phy3250-ubt-prms"

0x000000190000-0x000000590000 : "phy3250-kernel"

0x000000590000-0x000004000000 : "phy3250-rootfs"

The new one is:

Creating 5 MTD partitions on "lpc32xx_nand":

0x000000000000-0x000000064000 : "phy3250-boot"

0x000000064000-0x0000001f4000 : "phy3250-uboot"

0x0000001f4000-0x000000204000 : "phy3250-ubt-prms"

0x000000204000-0x000000604000 : "phy3250-kernel"

0x000000604000-0x000004000000 : "phy3250-rootfs"

Could anybody or any document tell me why? Will this mapping be changed again in the future?

This changes impact the burning procedure of our sample target!

Dear NXP friends,

After using "ltib -m distclean" and re-build the kernel, the booting becomes kernel panic, the build config is just the same as old one. Is there any modification need to be change with the menuconfig? Thank you.

The panics messages:

   ........................................................................................

Further such events for this erase block will not be printed
