Hi,
I recently bought a Swisscom pad (actually a simpad cl4),
more details about the hardware can be found in my previous
thread.
When trying to install the last official opensimpad version
(i.e. 0.8.1) I ran in to a lot of problems, which were
mainly due to unprecise or lack of documentation.
First off some installation instructions refer to buttons
by letters (at least r and f), but I have not found
any documentation for the association between these
letters and the actual keys on my simpad (maybe
the swisscom pads are labelled differently from
normal simpads?).
------------------------------------------------------
So is there any common letter key association for simpads?
------------------------------------------------------
I decided to use the key with the small rectangle and
interpreted reset as the r key, this seemed to work.
The next problem is the advise to erase
the flash before installing. According to the
docs this requires a booloader >= 2.5.3, but the latest
version available for small cl4 models is 2.5.1, thus
it is not possible to erase the flash.
I decided to skip this step, though the docs, explicitly
warn because of non immediate problems that might result,
the question is still:
------------------------------------------------------
What is the correct way to flash opensimpad on a
cl4 simpad, can I use the sl4 bootloader or is an
cl4 version of this booloader available?
------------------------------------------------------
Finally I want to use part of the ram as a ram disk.
For this purpose I found appropriate kernel images,
but there is no instruction about what to do with it.
--------------------------------------------------
I guess I can simply flash the kernel images like I flashed
the initrd... image, but I'd like to have a confirmation
before I do this.
---------------------------------------------------
By the way, it is not quite clear to me wether it is
possible to write to flash with the 0.8.1 release.
I concluded from some remarks here, that writing
to flash is not possible from within linux
(I think jffs2 would be necessary).
Despite this I could store a few MB on my simpad
and I had the impression that the files were
stored in the flash ram.
So since I have to patch my kernel for the mmc slot and
I'd also like to be able to write to the flash
I decided, to try to build my own images
(see next thread), thus these questions will hopefully be
not to important for me anymore, but answers are still
interesting and might helper other people who bought
the swisspad.
regards
Sascha
P.S. I found some Siemens internal informations on emule,
that state, that the flash ram is only specified for
1000 flash cycles, thus it might not really be a good
idea to use it via a file system anyway....
