Thanks for the update
Do you have a simpad with the a flash mod?
I hope I find some time to test the loader (currently uni is eating all my time )

If you like to further hack at the uboot front - adding some wake up code would be awesome!

hi,

In theory you should only need to replace [1] those lines (simpad.h).

Code: [Select]

#define PHYS_FLASH_SIZE         0x02000000      /* 32 MB */
#define PHYS_FLASH_BANK_SIZE    0x01000000      /* 16 MB Banks */
#define PHYS_FLASH_SECT_SIZE    0x00020000      /* 128 KB sectors */

here [2] is a short description about how I build the loader a year ago

happy hacking
nice

You can try to get rid of your home partition to gain more space (if you own a sl4/slc)

hi,
you need to make the j-tag mod [1]. You should then also be able to save the rom with urjatag [2] or jtagtools. without jtag you may not be able to reflash the old bootloader if anything goes wrong with flashing it.
angstrom is currently the best supporting distibution. Please read opensimpad.org it contains most of the informations you need. Even if the site needs some updates

best regards

hm, the good news is you can flash the flash now. the bad news bootldr cannot handle it :/
i don't know what is the latest version of bootldr for the simpad I once saved this one [1]
Slims and I tried to port uboot [2] [5] and redboot (Slims alone) [3] [4] to the simpad but both are not stable but maybe easier to patch for you.
For all 3 you will need to write a patch for the flash.
uboot is the most common on other devices nowerdays.

Hi, you can flash this [1] hh.org bootldr. You are right in your blog the jtag tools are only capable to recognize one chip. urjtag [2] can use both chips. the hh.org loader has hardcoded addresses to use the second chip. so you may not be able to use bootldr to flash an image but you shuld be able to boot a kernel from an cf card. or flash the image with urjtag. but it may be neccessary to update the adresses in bootldr an kernel.

best regards
nice

btw. because of university stuff i am not able to read the forum frequently. but i can try to help a bit but cannot promise

1) Will the CF WiFi card work with any of the linux based images?
-> The WiFi part of the card should work. The memory part do not work! And it will only be fixed if you provide kernel patches.
I recomand the i-gate card which i use with wpa.
2) Which image is best for the purposes I have described? I am quite tempted by the Opie image.
-> Angstrom images are a good choice. I personaly use the opie image and like it a lot but the x11 image is also fine.
3) Are the packages kept fairly up to date?
-> Well - yes and no.
The stable branch gets only bugfixes (so the stable image)
The unstable image gets a lot new packages but changes often and also breaks some times!
And no - you cannot mix the unstable/stable feeds
I use the unstable for developing and the stable for daly work. If you like a package backported then you can add it to this list [1]

Hi, did you try out to remove your home parition [1]?

It should be possible to get the chips at memphis.ag. They can find a matching chip for you.

The main problem is that you need to rewrite some stuff of the bootloader. There is some code for the adresses of the chip. Maybe you also need to change a line or two at the kernel -I cannot remember and have no source to look at here

If you get the prices for the chips please post them here.

An alternative would be the mmc/sd mod, but the driver for it is currently broken

I hope I will find some time to make the mmc/sd mod and for looking at the source

best regards
mr nice.

SIMpad forum / New Stable Angstrom Simpad Images Available (including Opie)

« on: October 27, 2008, 12:19:10 pm »

It is just the panel applet. In newer versions of opie it works. I don't know when new opie releases get into angstrom stable. it works with angstrom unstable. currently the autobuilder does not build unstable images for simpad. I build some from time to time. I can offer to upload them. But for unstable there is currently no konqe.

You can use the stable release and change the birghtness with a command.

e.g.
echo 200 > /sys/class/backlight/simpad-mq200-bl/brightness
you may also edit the file 0 - 254 are valid values.

with writing 0 or 1 to
/sys/class/simpad/latch_cs3/display_on
you can toggle display on off.

There are some plans for r19 image but i lost track about it.

hi,
thanks for testing. Is the mmc mod working for you with r18? others reportet that it is currently not working.
usb is not working with r18 because we currently have no driver for it. there was recently a contribution for zaurus and it should be possible to port or use it without modification on the simpad. At the moment I have no time to look at it .

btw: if mmc mod is working for you, you may be able to boot from mmc with kexec. there should be a kexec support at the kernel but I found no time to test it.

best regards
mr nice
