building opie-image with oe

Hi,
   I'm trying to build an opie-image with the openembedded toolchain, 
using the opensimpad.conf and linux-ulibc as a target.

Now, when bitbake wants to build the kernel, it complains that 
arm-linux-ar is missing (and probably other tools too).

Now, the correct name for the binary with ulibc is arm-linux-uclibc-ar 
(its was build correctly before).

Where is the correct place to fix the problem, rather than making ~30 
symlinks ?

regards,
     Michael

How to back to oryginall bootloades

Hi all
I installed opie 0.9.1rc1, first, I serload blupdater.img, second I send 
system image with serial port, all works very fine. Now, I`d like come back 
to WinCE and I do:

boot> set override = 1
	setting param <override> to value <1>
boot> pflash 0 40000 0
	addr=00000000
	len=00009C40
	protect=00000000
	Protect=00000000
boot> load bootldr
	partition bootldr is a bootldr partition:
	requiring a bootldr or parrot image.
	After receiving file, will automatically uncompress .gz images
	loading flash region bootldr
	using ymodem
	ready for YMODEM transfer...
	362F95577901AFF5C29BA77867A9D33B simpadSL.rom
	00022EC0 bytes loaded to C0000400
	wrong magic: E3A01E27
	parrot word 0 ->0xE1A00000
	Expected ->0xEA0003FE
	parrot word 0x1000 ->0x55AA5A5A
	Expected ->0xE321F0D3
	You must load wince BEFORE loading Parrot
	Not loading invalid bootldr into flash

I used simpadSL.rom and simpadCL.rom from sourceforge.net

Re: How to back to oryginall bootloades

i did the switch back to WinCE, but the way i did it...well it was more 
like brute force than finesy. All i did was to take original bootloader, 
which you can find here 
http://sourceforge.net/project/showfiles.php?group_id=65409&package_id=77867 
(i have all the bootloaders needed on CD, so mail me and i will send 
them to you). To tell the truth i couldn't serload some of the 
bootloaders   but in the end i managed it out (please don't ask me how i 
just don't remember ;-) ) After  bootloader loaded i've erased the flash 
(from bootloader) and next i've copied wince image with serload. I had 
problems with serloading winCE image with some of the boot loaders, but 
after trying few bootloaders i've finally serloaded the image.
OK i know that it's a way of stupidity, but i'm kinda n00b with linux & 
embeded devices.

RE: How to back to oryginall bootloades

Hi Kris

Looks like the bootldr requires a special header for downloading the old bootloader.
Bootldr tries to protect itself from accidental overwriting.
You need to download the PBL not the normal bootloader first!

Walter

Re: How to back to oryginall bootloades

I have this answer from Alex:
don't use "load bootldr" to reflash the wince one, use "load flash 0" after 
you have unprotected the flash. This will solve your issue.

I try this and all works very fine
Thanks Alex
Kris

blupdater.img on T-Sinus Pad

I tried the new bootldr on my T-Sinus PAD.
Attached is the output after flashing opensimpad-0.9.0rc1_opie.jffs2
with a cf card.

If I should do further testing, please contact me.

Re: blupdater.img on T-Sinus Pad

Hello,

the bootldr included in the blupdater.img doesn't wotk on 16MB devices. But
at least it doesn't brick the pad like the first version for the SL4 did.

I need somebody (Peter?) to remove code for the 24MB root partition (and 8MB
home) in the latest version for the CL4. Peter already removed the code for
the second flash chip as that caused a major problem with the first attempts
to upgrade the bootldr with that (when the jffs2 image was installed from
this version the writing started at block 0 - which of course overwrote the
bootldr). 

The only thing i can think of that is different from the original attempts
from Alex tried while porting is the code defining the 24/8MB partitioning.

Peter could you build a version with the corrected code and send it to me. I
will modify the blupdater.img and also supply a link for those needing only
the bootldr (to salvage that mislung first bootldr installation).

Chris Martin

AC detection explored

Hi,

at the forums, some users reported problems with AC detection. The battery
applet shows "Charging, external power disconnected" in that case and the
blupdater complains about missing AC power. My pad, while charging,
periodically switches between power connected and disconnected, what makes
the screen go bright and dark in a 10 seconds intervall. This has nothing to
do with the new OE build, the OZ builds have had the same problem.

So I hooked up my SL4 to an adjustable PSU and watched the battery applet
while slowly turning the voltage control. As soon as the voltage dropped
below 12V, the applet showed "external power disconnected". 12V is the
nominal voltage of the AC adapter, so putting the threshold at just 12V
seems a bit optimistic to me ;-).

Looking through the kernel patches at OE, I came across the line
2004/03/31 mickey     | +#define MIN_SUPPLY            12000 /* Less then
12V means no powersupply */

Maybe someone of the kernel coders can verify this and change the value to
11000 or 10000 for more reliability.

Sounds reasonable (to me at least). Juergen, Walter, Ralf, can I get a
confirmation from you?

The original code is by Jürgen, but the usage is by me. So I feel
qualified too. :) The original definition is more or less this:

/*
 * We have two types of batteries a small and a large one
 * To get the right value we to distinguish between those two
 * 450 Units == 15 V
 */
#ifdef SMALL_BATTERY 
#define CALIBRATE_SUPPLY(a)   (((a) * 1500) / 51)
#define MIN_SUPPLY            8500 /* Less then 8.5V means no
powersupply */
#else
#define CALIBRATE_SUPPLY(a)   (((a) * 1500) / 45)
//#define MIN_SUPPLY            14000 /* Less then 14V means no
powersupply */
#define MIN_SUPPLY            12000 /* Less then 12V means no
powersupply */
#endif
