Steps to build the kernel:
|
|
|
|
Download and install the cross toolchain gcc version 4 for Linux 2.6.
|
|
|
|
$ cd /opt
|
|
$ tar xjf mipseltools-gcc412-glibc261.tar.bz2
|
|
$ export PATH=/opt/mipseltools-gcc412-glibc261/bin:$PATH
|
|
|
|
Download the linux kernel tarball linux-2.6.24.3.tar.bz2 and unpack it:
|
|
|
|
$ tar xjf linux-2.6.24.3.tar.bz2
|
|
|
|
Download the latest kernel patch and patch it to the kernel tree:
|
|
|
|
$ cd linux-2.6.24.3
|
|
$ gzip -cd ../linux-2.6.24.3-jz-yyyymmdd.patch.gz | patch -p1
|
|
|
|
Make defconfig of the JZSOC based platform, eg:
|
|
|
|
$ make apus_defconfig (JZ4750 based APUS board)
|
|
or
|
|
$ make pavo_defconfig (JZ4740 based PAVO board)
|
|
or
|
|
$ make pmp_defconfig (JZ4730 based PMP board)
|
|
|
|
Build the kernel:
|
|
|
|
$ make xconfig
|
|
$ make uImage
|
|
or
|
|
# make zImage
|
|
or
|
|
# make modules
|
|
|
|
|

* Fixed a bug of YAFFS2 on JZ4750 when using BCH ECC algorithm.
|
|
|
|
linux-2.6.24.3-jz-20090218.patch.gz
|
|
|
|
* Support Jz4750
|
|
* Converted MTD from 32bit to 64bit to support the NAND larger than 2GB, and yaffs2 was
|
|
modified accordingly.
|
|
* Supported multi-plane operation and multiply chip selecting for NAND flash.
|
|
* Whether NAND multiple planes operation for one partition is used or not could be
|
|
determined by the value of use_planes in partition_info[] in drivers/mtd/nand/jz47xx_nand.c
|
|
* Modified yaffs2 utils mkyaffs2image to support writting 4KB pagesize NAND and enable
|
|
writing soft reed-solomn ECC for yaffs2 file system information in oob area of MLC nand
|
|
|
|
linux-2.6.24.3-jz-20080926.patch.gz:
|
|
|
|
* Fixed a fatal bug for mplayer, which may cause some files cannot be played and the system is crashed.
|
|
Updated file: arch/mips/jz4740/proc.c.
|
|
* Modify jzfb_mmap() for cacheable LCD framebuffer access.
|
|
|
|
linux-2.6.24.3-jz-20080815.patch.gz:
|
|
|
|
* Modify ipu interface to toggle PID of MPlayer in TLB.
|
|
* Modify OSS ioctl function to play movie with mono channel better.
|
|
* Check whether the free block of nand is erased before erasing it, 'unsigned int' instead of
|
|
'unsigned short' was used to store block number, and heap sort for lifetime after
|
|
erasing a block was replaced by another faster method.
|
|
* Cache read was used in nand_read_page_hwecc_rs() for Jz4740.
|
|
* Faster timing in REG_EMC_SMCR1 whose value is 0x09221200 was used.
|
|
* Supported 4KB page size nand
|
|
* Soft reed solomon ECC was supported for yaffs2 information which is 16 bytes in nand
|
|
oob, and it should be used for MLC nand.
|
|
* Added support to generate any frequency baud rate of uart for both Jz4740 and Jz4750.
|
|
* Modified Jz4750's INTC, CIM, TSSI, macros.
|
|
* Combined Jz4750 SLCD Controller support into drivers/video/jz4750_lcd.c, which now support
|
|
LCD Controller, Slcd Controller and TVE. And add smart lcd panel TRULY_TFT_GG1P0319LTSW_W support.
|
|
* Add Jz4750 LCDC and TVE driver.
|
|
* Modified CONFIG_FB_JZXXX macros, rename drivers/video/jzslcd.x to drivers/video/jz4740_slcd.x
|
|
* Add jz_clocksource, upgrade the system time's accuracy from 10ms to about 1(or 2) us.
|
|
but the system timer remained 10ms.
|
|
* Updated UBIFS.
