Angstrom & OpenZaurus / collie and kernel from 3.5.3 upgrades

« on: June 27, 2005, 07:36:07 pm »

To remove the warning, you need to remove/rename a script in /etc/init.d/ (checkver something like that - no Z to hand atm I'm afraid).

OK but how would you do that when the Z will not go passed the sleep message.

works fine for me, after a minute or two it continues booting.

Angstrom & OpenZaurus / Oz3.5.3 (collie) On/off Button Problem

« on: June 27, 2005, 04:05:16 pm »

The same bug seems to exist on Poodle (sl5600) as well. I just tested it under OZ 3.5.2. It does not suspend, but on the main console window (vt1) I get  messages from the powerirq_handler for all of these buttons.

Yeah - the GPIO responsible for the suspend request was being triggered from all those buttons too. I checked and this behaviour was on earlier releases too (you can check by loading the registers module and monitoring the lowest bit of /proc/cpu/registers/GPLR). I added an extra test for a Cancel keypress (through the normal keyboard driver "pressed" matrix) and it works fine now.

I've been looking at the crash-on-suspend bug. It seems to be fixed after some changes (the original APM code is really horrid, there were some serious bugs), but now the usbnet driver (and then the whole kernel) seems to go down after the third suspend or so (if the script in /etc/apm/scripts.d is disabled, suspend/resume works fine). I'll have a look at that.

Angstrom & OpenZaurus / Oz3.5.3 (collie) On/off Button Problem

Someone please confirm this: does the Z suspend with:

 - Cancel button
 - Right button
 - Center button
 - Menu button

I've been doing some testing - all those seem to trigger the suspend GPIO. And they all happen to be the outermost row on the extensible keypad  (misconfigured driver chip? The sleep input is a GPIO pin, which presumably is some special output from the keyboard scanner chip (LoCoMo?). It is being triggered by all buttons in that row, not only the Cancel button.)

EDIT: fixed. Patch is in bugzilla and was commited to OE tree. This bug was probably in the kernel for a while, but previous userspace behaviour probably overrode it.

I am willing to help as much as I can on this problem. I've been testing with a current OE build of bootstrap-image. It suspends when pressing cancel, but if apmd is running and the device is there, it fails to resume and needs a battery swith flip (and then reboots). If I remove the device, it suspends properly but kills usbnet (because the suspend/resume scripts do not run). Killing apmd of course has the same effect.

5x00 Hardware / Pictures Of The Inside Of A 5600?

at least my 5500 has CSP BGA ram chips. So I guess the 5600 would too.

Careful though. I've worked with MAX232 and microcontrollers - the MAX232 maps -12V to +V and +12V to 0V. But the Z works the opposite way. So you need to add some logic inverters. Or transistors. I have wired the Z to a PIC microcontroller for a hardware project, and that's how I found out that everything was reversed. A couple transistors were fine for my project.

Yo conseguí la mia por eBay. Hay por ahi alguna tienda que la vende tambien. El modelo WiFi+BT es dificil de conseguir. El mas comun (el que tengo yo) es el solo WiFi. Siempre puedes ponerle una tarjeta BT CompactFlash o conectarlo por el puerto USB host.
