smp86xx LZMA kernel loader for the pirelli/arcor stb ip100

[Hoernchen]

based on https://svn.openwrt.org/browser/trunk/target/linux/generic-2.6/image/lzma-loader/src/
includes the lzma sdk http://downloads.sourceforge.net/sevenzip/lzma432.tar.bz2

build lzma

Code: [Select]


tar xzf lzmaloader.tar.gz
cd lzmaloader
make -C lzma/C/7zip/Compress/LZMA_Alone -f makefile.gcc

then compress your vmlinux.bin

Code: [Select]

lzma/C/7zip/Compress/LZMA_Alone/lzma e /path/to/linux-2.6.15/arch/mips/boot/vmlinux.bin src/vmlinux.lzma -lc1 -lp2 -pb2
build the loader

Code: [Select]


cd src
make


then use yamon to load the resulting lzma.bin, for example by tftp:

Code: [Select]


net init; load -b tftp://192.168.2.3/path/to/lzma.bin 0x91400000; go


Caution: This will enable the usb ports before starting the kernel, so do not use it on a different smp based box without looking at the code first.

-fixed linker script and usb enable, previous version did not enable the usb ports. doh.

Hi,

Ideas?
Thank you.

--- EDIT ---

Partially solved.
Using a toolchain with gcc 4.0.4 works correctly.
Using a toolchain with gcc 3.4.2 doesn't work.

How big is your vmlinux.lzma ?

Could you explain me the meaning of the number 0xC in the following code

Code: [Select]


gpiodir = ((( 0xc & 0xffff) << 16) | 0xffff);
gpiodata = (( 0xc & 0xffff) << 16);
gbus_writel(0x10500, gpiodir);
gbus_writel(0x10504, gpiodata);


I'm trying to compare it with the commands inside a shell script in the pirelli original fw:

Code: [Select]


/bin/gpiotest WRITE 5 1 # usb reset high
/bin/gpiotest WRITE 2 0 # usbA enable (bottom USB slot on HY100 STB)
/bin/gpiotest WRITE 3 1 # usbB disable


but I can't understand.
Thank you for your support.

0xc = 0b1100 ... gpio 2&3

update for SMP863x Rev C 

now USB ports are correctly enabled !

update for SMP863x Rev C

Many thanks to you mce2222 and to Hoernchen!
Now owners of STB HY100 are ables to load AZBox adapted fw following detailed informations in
http://hy100wiki.algasystems.net/wiki/doku.php/azbox_firmware
and using new lzmaloader from mce2222 instead of the one in the wiki!

I will try soon and I will be back to you with my results!

I tried the loader and I found some solutions:

- To get around an
"unrecognized opcode `__asm__" Problem im e.g. asm/hazards.h:172
add "-D __ASSEMBLY__" to Make Rules

- The
"Warning: Writing section xxx to huge"
can be prevented by changing
*(.rodata)
to:
*(.rodata) *(.rodata.*)
in the linker script (lzma.lds.in)

[heimi666]

I finally
- compiled a 2.6 kernel
- added loader
but without success, my kernel won't boot and usb didn't work either. (coprocessor error)
So I decompresses the provided kernel compressed it again and added the loader. Booting was successfull, no usb but nfs was possible.
The coprocessor problem was fixed by building vmlinux.bin not vmlinux which was ELf (silly me).
After applying ltrace (patched to mips by freetz.org guys) to a programm called usb_enable in my rom firmware I could extract the sequence to enable usb on my plattform, but I also found out that this could be managed directly in YAMON with appropriate gw32 commands, but now I'm able to build a loader with usb enabled.
