kernel panic: no init found... 1870 2
Started by tozyagcilar
Hi,
I think I have followed all the instructions on the 'LH79520-10: Installing the Lineo BDK and Logic Linux Source Tree' document. However, when I try to boot from CompactFlash I get a kernel panic that tells me the following:
RAMDISK: Couldn't find valid RAM disk image starting at 0.
Freeing initrd memory: 16384K
EXT2-fs warning: mounting unchecked fs, running e2fsck is recommended

LH79520 and uClib 1720 1
Started by marius.tannum@power-one.c
Hello,
I have tried to compile 2.4.17-rmk2 (with the patches: patch-2.4.17-rmk2-lineo-*) using an existing uClibc cross compiler v. 0.9.11 . I have been using this cross-compiler for an arm720 before (cirrus 89712). I placed the VMLINUX file on a compact flash and tried to load without success (se error message below).
Is it possible to compile the kernel and lineo patches with uClibc
Thanks,
Marius Tannum

IAR EWARM and startup code 4495 1
Started by Patrick Perdu
Hi all,
I recently had questions here about SDRAM initialization and startup consideratins.
I figured it out so I would like to ensure at least taht nobody blocks stupidly as I did. Here is the CStartup.s79 file I ended with.
Please note tnhat the stacks are not initialized, the interrupt vectors are neither. All this must be done, I elected to do it in C in the low_level_init() function called by IAR system after (very) low level init.
Of course to init the vectors, we need to have them in RA...

code samples 1729 5
Started by alan.ambrose
Hi,
Can anyone direct me to some straight forward code samples for display handling (e.g. squirting a bitmap at the display) and/or tcp comms
Also is there a recommendation for which jtag works with the GNU tools (if any) and how to set it up. Alternatively, a better development environment / jtag combination

Does touchscreen work ? 1717 2
Started by miguelgu
Working with Linux BSP from LogicPC it's a little hard. I want to use the touchscreen to evaluate a new design and I it doesn't work fine. It's imposible to calibrate. Anyone know any bug with touchscreen Or I have missed some configuratiion with the development kit !. Please Logic, help to use your development kit. It will be very disappointing to discard this board if the touchscreen doesn't work.

Problem with mmap() & noncached memory 1607 1
Started by Deleted User
How do I memory map(mmap()) a region to user space as noncachable memory
The problem appears to be that the system has mapped the memory range as cacheable and caching
needs to be disabled. I have written a device driver that exports a mmap() function that maps the
appropriate region as follows-
if (remap_page_range(vma->vm_start, offset, vma->vm_end - vma->vm_start, pgprot_noncached(vma->vm_page_prot)))
return -EAGAIN;
Any help would be greatly appreciated...

Greetings!
while downloading logicpd's hacked bdk scripts i noticed the website says '1.0.0c' while the download is 1.0.0b

6/25/2004 lpd linux LLH79520 1.0.0c.tgz .tgz 29.09 Mb
The link tells 1.0.0b:

http://www.logicpd.com/downloads/152/lp ... 1.0.0b.tgz
When/where is the updated 1.0.0c available
Does it incorporate the changes other users already mentioned/fixed manually (like http://www.logicpd.com/support/tdg/viewtopic.phpt=22 )

Do I Have A Wrong Version of BDK or What? 1836 5
Started by Kenneth Lerman
My BDK is ’02101lh9520bdk.iso’
The patch file I downloaded contained: lpd-linux-LLH79520-02.tgz
The 'white paper' refers to: tar xzvf lpd-linux-LLH79520-04.tgz
Clearly NOT the same, but I downloaded it today, so what the heck, I continued.
The tar command worked fine... sort of. But the file ownership was messed up because the owners of some of the files were not root and I was running as root. (I bet there is another switch to tar that will set the owner to me even if I'm root.)
So I did ...

ANSWER: NFS Hogs The System and Causes Screen Tearing 1542 1
Started by Kenneth Lerman
Updated: 1 October 2004 --
(Partial) Answer: Screen tearing is caused by the fact that the processor is not fast enough to support the refresh rate. Reducing the refresh rate to 40 Hz solves the problem -- at the cost of some flicker. 50 Hz did NOT solve the problem. I'll try 45 Hz when I get a chance.

Qt 3.3.2 touchscreen 1529 1
Started by mike tesch
A general FYI for using Qt3 on the 79520 Linux package:
We have a user who has ported Qt 3.3.2 to the 79520 kit. He found that in order to get the touch screen working correctly he had to modify the file qt-3.3.2/src/embedded/qmouselinuxtp_qws.cpp in the same way that the Qt 2.3.2 file qt-2.3.2/src/kernel/qwsmouse_qws.cpp was modified by the Lineo patches.

How Can I Build My Own "Motherboard"? 1647 1

I'd like to build my own board which acts as a motherboard for the Card Engine. But I don't have anything documenting the physical footprint of the card engine. I have artwork, but clearly a pdf file is not a reasonable way to generate the measurements I require.
A set of Gerber files would work, but my preferred format would be 'Eagle' format. That way I could just incorporate it into my design.
Another problem, of course, is that I'm not really setup to build boards with surface mounted c...

Problem with TOUCHSCREEN 1562 1
Started by Kenneth Lerman
I run the paint program. Then select a color.
When I touch the screen, the point I touch gets a pixel set, and then as long as I hold the touch, other pixels are set -- usually in an area about half and inch to the right and 3/8 of an inch above the point I touched. They form a 'cloud' in that area.
I assume this is a bug. -- although it could be a feature.
More Info:
I've written a program to print the raw data from the touchscreen. The results show roughly the behavior I've seen:
