White screen issue

[龙智]

I compile the latest OpenEzx kernel(2.6.30) , and upload it to my E6 via
boot_usb and gen-blob tools(following Getting Started -
OpenEZX
),  sudo ./boot_usb setflag usb
sudo ./boot_usb gen-blob 0
and then,
./boot_usb zImage-  "" 
after a few seconds, the screen turns white, and nothing else happen. It
looks like the kernel might not be boot normally.
What's wrong with it?

What .config file are you using?

Please, assert that you are using the latest openezx.git, that you are
on the ezx/current branch, and that you are using the .config from
arch/arm/configs/ezx_defconfig.

If you still have a white screen under these conditions, boot the
kernel, and cause the white screen.

Remove the battery, and as fast as possible insert the battery again.
Enter gen-blob usb mode and run:
$ boot_usb read 0xa000 31457280 memdump
$ gzip memdump
and send me the memdump.gz file. (please dont send it to the mailing
list)

You can also flash gen-blob, so you dont need to send it to MBM every
time. But it doesn't matter in this case.

To prevent your phone to auto powering-on when you insert the battery,
simply remove the usb cable before inserting the battery.

I haven't flash gen-blob yet.

I got such messages:

This should work. I see no reason for it to fail if you can use boot_usb
to upload the kernel. Please, try to figure out what is wrong, its
exactly the same as uploading the kernel to gen-blob.

Hi Daniel,
I'm on the ezx/current branch, and using the .config file from
arch/arm/configs/ezx_defconfig.
I tried to get memdump but failed. When I insert the battery back, the phone
automatically boot into the stock operating system, so I haven't chance to
enter gen-blob usb mode(BTW, I suppose I should run boot_usb gen-blob 0 to
enter gen-blob usb mode, right? I'm a newbie)

Re: White screen issue

[龙智]

I tried many times, and exactly get the same result. I did that as
following:
1. upload kernel to the phone, cause the white screen
2. remove the battery, and then put it back as soon as possible
3. run boot_usb setflag usb & boot_usb gen-blob 0 to enter gen-blob USB
mode, then LCD display:
OpenEzx blob 090504
USB ready
4. run boot_usb read 0xa000 31457280 memdump, I got:
$Id: boot_usb.c 2462 2009-04-12 22:55:17Z ao2 $
Serching for EZX phone: Generic Blob found.
Downloading: FAILED: download failed
 is there anything else I should pay attention?

BTW, when I flash gen-blob to the phone(
http://wiki.openezx.org/Dual_Boot_GEN2) , I also get the same error.

Dont know. It "Just Works(TM)" here. Im using gen-blob on flash, but as
I said, it shouldn't make a difference.

Check your host dmesg to see if you have an usb reenumeration after you
send gen-blob to the phone. If not, then unplug/plug the usb cable to
force the reenumeration.

Daniel, can you tell me how to check host dmesg? I've never used this.

Daniel,
When I send gen-blob to the phone, I got a warning:
$ sudo ./boot_usb gen-blob 0
$Id: boot_usb.c 2462 2009-04-12 22:55:17Z ao2 $
Serching for EZX phone: E2/A1200/E6/A910 found.
Uploading kernel: 100% OK
Warning, params is not supported on your phone, please consider using
gen-blob
Calling the kernel...
DONE

does it matter?

Just write "dmesg" on your terminal. This will show your host kernel
messages.

Daniel,
when the phone enters gen-blob USB mode or unplug/plug the USB cable, dmesg
output:
[  884.836686] usb 2-2: USB disconnect, address 4
[ 1118.136555] usb 2-2: new full speed USB device using uhci_hcd and address
5
[ 1118.311724] usb 2-2: configuration #1 chosen from 1 choice
I don't see messages such as:
usb0: register usbnet at usb-:00:10.2-2, pseudo-MDLM (BLAN) device,
8e:36:06:d5:16:9d
it seems usb doesn't work.

Re: White screen issue

[Fred .]

Ok, i seem to read on the irc log, that the problem is solved, 龙智 was using
a different toolchain for building gen-blob than the one the developers
recommends, (some angstrom's or the one from OE are known to be good, it is
documented on the wiki) 龙智, can you confirm this?

Also, does your system, (dmesg) now show you the same vendors, id_product,
and so like my log did?
( just curious about it :) )

Thanks.

Re: White screen issue

[龙智]

Hi,
When I use OE to build kernel, the white screen issue is resolved. Now
kernel can boot normally.
Thanks Daniel and Fred.
