BODY { font-family:Arial, Helvetica, sans-serif;font-size:12px; }Hi,
I have finally to got round to start on putting debian etch on my
partner's Elonex OneT+. I have been using ard's site to get started.
This where I have done.
Firstly, I built the first and second stage of the debain build on
my MIPS debian QEMU VM. I (sort of) followed the instructions on the
DebianChroot page and put the Debain install on 2nd nandflash
partition.
I then tried to run the "Kernel of the week" using
Fn+LeftShift+LeftCtrl. It actually flashed the kernel and boot (like
the Letux400).
I then proceeded to boot Debian by pressing F3 and it worked and
booted Debian. After playing with it, loading xorg (and Matchbox for
my sins) and downloading ard's xorg.conf. I noticed the device
drivers were not there, so I created them. Now X starts but there
seems to be no session manager runs, i says something about there
being no root/.xsession file.
This is where I am up to. I was wondering my order of things was
wrong. Now I have debian booting on the 2nd flash, I was going to
redo the first stage ( on my x86 Debian VM) and then do the second
stage inside a booting etch (with kernel modules, and devices from
the original OS).
I will try to write it up this time, as well.
Are there any tips you can give.
Lastly, I noticed that Ingenic has release a patch for the 2.6.24
kernel. I have attached the changelog on here. I was not too sure if
you have seen it.
Cheers,
Richard Mottershead
*********************************************************************
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

linux-2.6.24.3-jz-20090226.patch.gz
* 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.

linux-2.6.24.3-jz-20080526.patch.gz:
* Rewrote all of the UBI and UBIFS codes and their utilities.
* Modified MMC/SD driver jz_mmc.c to support PM callback.
* Fixed a bug of mtdblock-jz.uu of using the badblock_table.

* Modified sound/soc/jz4740/jz4740-i2s.c to support 32KHz PCM sample.
* Ported new mtd-utils and mkfs.ubifs.
* Added jzslcd.c for Smart LCD framebuffer driver.
* Modified rtc_jz.c to use some functions in rtc library instead of our

* Added jz_keypad.c and gpio_keys.c for scan keypad drivers.
* Added block-jz.c to support block device layer on top of ubi.
* Modified jz4740_udc.c to enable the suspend irq when host unloads us.
* pavo_defconfig: select CONFIG_WIRELESS_EXT, CONFIG_PNP and
