Can the 5500 / 64-0 Hybrid ROM with Qtopia 1.6.2 also use the 2.4.18 kernel update and async config?  Is it neccessary to start the installation with a sharp 3.10 already installed? I've played around with the Hybrid rom a little and it's great - like having a new Zaurus again.


No, Cacko kernel will not work with Hybrid ROM. The kernels are a bit different - Hybrid ROM has JFFS2 support and different partitions layout.

I did not make a commulative patch, I prefer to apply existing patches separately. There are only a few patches applied, which are available for download in OZ and OE buildroots.

- battarey % patch

- IRDA QOS FIX

- Orinico/Spectrum drivers 13e with monitoring mode

I'm attaching a config file for the SL-5500 - the only few differences from Sharp's default are:

- smaller console fonts
- Sharp logo removed
- Wireless Extentions enabled
- CONFIG_FS_SYNC option is off

Let me know if that helps you

You can only use this set of tools to compile the kernel:

Patches are supposed to be applied on top of Sharp's kernel.

To disable auto-suspending of serial pcmcia devices upon resume, apply
the following one-liner to linux/drivers/pcmcia/cs.c:


+++ cs.c Wed Mar 31 11:15:10 2004
@@ -749,8 +749,8 @@
}
#endif
/* power off serial card */
- if (pcmcia_resume_handling)
- serial_card_power_off(s);
+// if (pcmcia_resume_handling)
+// serial_card_power_off(s);
}
#else
if (verify_cis_cache(s) != 0)

Very strange problem with the kernel:
1)Initialization of home directory seems to be too slow. Something wrong with my card? I changed the driver to the one in download section, which would boost the r/w speed in sharp's rom, still helps little. I have updated the initrd.bin file to contain the .rom_options, also with the driver. But it is still so slow. sad.gif It has been in the updating for about 5 minutes. sad.gif

2)Suspend hang: When I push the cancel button to suspend it, it only turn off the light, and then all other operations are useless. Only by turn the switch to replace battery mode, then push the button again, it will begin to reboot. sad.gif

3)Crash: it seems that this is the famous 2 reboots crash. I need to reboot it when I need, but there is no suspend in it, then when issuing a reboot, it will crash, only push the reset button will solve the problem. sad.gif

4)Backup content can't be restored. sad.gif

It seems there are too many problems with my Zaurus(SL5500).

Try another SD card.

Did I write that this kernel resolves the issue?

Please, read this topic carefully from the very beginning. This problem has been solved next day after the kernel was out...

Thanks maslovsky!
Your great work benefits us all. smile.gif
It seems that the problem comes from the SD card. Any one can confirm: Kingston 256MB SD-M256B1 seems to be too slow to work in ordinary usage. sad.gif

Sorry for my carelessness. I just read it.
Thanks again for your help.

I changed back to Sharp 3.13 rom with the updated 32-30 kernel, great plasure to use the SD card. The read/write speed is great. It seems that there is something strange inside the 64-0 rom or kernel?

The only real difference is the amount of write operations to the SD card. If 64/0 memory layout is too slow for you, just stick to the default one. Use swapfile when you need more memory...

Thanks maslovsky!
I have met with IRDA connection with my laptop.Last time I won't have met with so many file transfer error, but upgraded to the new kernel,it seems that I have met too many! Often aborts in the very beginning, the dmsg shows that read error: expect 1 byte while read 2 bytes ? My hardware problem? Thanks!

submit by my Zaurus SL-5500! smile.gif

Sorry, I've only used IRDA connection a couple of times. I use bluetooth or WiFi since then, so I don;t know what might be wrong...

Just wanted to add my thanks to Anton for all his work on this - this rom *finally* allows me to connect to GPRS over IRDA to my Sony Ericsson T300.
