RE: [Ltib] Kernel panic after update the latest source for LPC32xx targe

Hi Henry,

There is a website going live in a few days that will track patch history better.

This won’t help you yet, so here are the latest updates to 2.6.37.8 and 2.6.34. You can also browse the CVS history of the ./ltid/dist/lfs-5.1/kernel/kernel-xxxx-lpc32xx.spec.in files to get patch history and view the raw patches in the /opt/ltib/pkgs directory.

Kernel version 2.6.27.8 updated 07/19/2010

Updated default kernel configs for PHY3250 and EA3250 boards
Added suspend to mem power management support
Fixed an issue with USB clock/enable disable that could sometimes prevent USB clock from starting
Fixed scatter/gather linked list support (fixes an audio issue)
Added support in DMA driver for scatter/gather specific for NAND and software burst enable
Re-sized and added/removed MTD partitions for NAND for EA and Phytec boards
Added DMA support for NAND/MTD for EA and Phytec boards
Removed wakeup event clear logic from IRQ driver when interrupt is cleared, not needed
Added a simple GPIO interrupt and event wakeup example for the Phytec board using the BTN1 button
Added wakeup support to the touchscreen driver
Added suspend/resume functions to the high speed UART driver
NAND/MTD driver now supports hardware ECC
Fixed and improved alarm functions in the RTC driver
Fixed and enabled gadget driver DMA support
Fixed an issue with the gadget driver where the USB D pulldown would get stuck asserted when the module was removed
Fixed several clock crash issues with the gadget driver related to module removal and cable removal

Kernel version 2.6.34 updated 07/16/2010

Fixed an issue with USB clock/enable disable that could sometimes prevent USB clock from starting
Revised SD card clock rate set, get, and rounding functions
Fixed scatter/gather linked list support (fixes an audio issue)
Added support in DMA driver for scatter/gather specific for NAND and software burst enable
Fixed a potential compilation issue in the ea3250.c file when the LCD is disabled
Re-sized and added/removed MTD partitions for NAND for EA and Phytec boards
Added DMA support for NAND/MTD for EA and Phytec boards
Fixed an issue with gpiolib that would return a wrong state for GPIO banks 3 input pins
Fixed several incorrectly named definitions (was LCP, now LPC)
Removed wakeup event clear logic from IRQ driver when interrupt is cleared, not needed
SD/MMC driver data handling completely re-written, now supports scatter/gather and is better optimized
Updated card detect, write protect, and power control logic for the SD card controller driver for the Phytec board (uses driver functions now instead of callbacks)
Added a simple GPIO interrupt and event wakeup example for the Phytec board using the BTN1 button
Added wakeup support to the touchscreen driver
Added suspend/resume functions to the high speed UART driver
NAND/MTD driver now supports hardware ECC
Fixed and improved alarm functions in the RTC driver
Fixed and enabled gadget driver DMA support
Fixed an issue with the gadget driver where the USB D pulldown would get stuck asserted when the module was removed
Fixed several clock crash issues with the gadget driver related to module removal and cable removal
Added default configurations in arch/arm/configs for the EA3250 and PHY3250 boards

And here is the u-boot 2009.03 changes updated 07/16/2010

Moved NAND driver to common NAND area, removed Phytec and EA NAND drivers
NAND driver now support hardware ECC
Added basic DMA driver for NAND support
Revised u-boot environment save locations and sizes (matches S1L? and kernel)

thanks,

Kevin

Dear Kevin,

Thanks again, I want to know where can I find a document for us to follow on the latest patch easier. For example, the change log in somewhere or not?

Hi Henry,

This was changed to fix an issue with potential overwrite of S1L application code (via nsave, nload) with the u-boot parameters.

If this occurred, the board wouldn’t boot u-boot anymore.

An additional u-boot partition (/dev/mtd1) was also added so u-boot could be updated from the kernel.

I don’t suspect this mapping to change again in the LTIB patch series.

Sorry, I hope this didn’t cause too many issues. These types of changes are rare, but sometimes they are needed.

thanks,

Kevin

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:

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