KITL is corrupted by LCD Driver

1.Release mode image runs with KITL enabled, hangs with KITL disabled

Hi,

I'm working on 6.0. I have unchecked 'KITL enable' and 'Kernel
Debugger' option in my workspace properties. Also the KITLIoctl call
in OEMInit is commented out. The message I'm getting on the serial
terminal is:

Jumping to image at 0x8000468C
Windows CE Kernel for ARM (Thumb Enabled) Built on Sep  6 2006 at

DCache: 64 sets, 4 ways, 32 line size, 8192 size
ICache: 128 sets, 4 ways, 32 line size, 16384 size


.. and then it remains stuck there. None of the drivers are loaded as
I don't get the RETAILMSGs put in the Init() routine of each driver.

This problem is not noticed in debug mode though. I believe that I'm
not able to disable KITL properly and some OS service is getting stuck
due to that in release mode.

Somraj

2.What is the difference of Active KITL and Passive KITL in perf

Thank you very much. Just like you say, I am confusing these concepts.

3.What is the difference of Active KITL and Passive KITL in performa

Hi,
   Now my Active KITL has some error, so I use the Passive KITL. But I feel that the Passive KITL has a bad performance,isn't that?

4.Kitl connection doesn't. kitl on 4.2 SH4

Hello again All

I've determined that the system seems to hang right after it enters
KernelInit. After trying it on an Renesas eval board, the very same
code runs fine and does not hang.

This is what the code looks like:
---------------------
void KernelInit(void) 
{
#ifdef DEBUG
    lpWriteDebugStringFunc(TEXT("Windows CE KernelInit1\r\n"));
#endif
    /* setup the well known system API sets & API types */
    SystemAPISets[SH_WIN32] = &cinfWin32;
#ifdef DEBUG
    lpWriteDebugStringFunc(TEXT("Windows CE KernelInit2\r\n"));
#endif
----------------------
On the debug output I get the first debug blurb, not the second. I am
not sure if it is hanging on the  lpWriteDebugStringFunc or assigning
SystemAPISets[SH_WIN32]. I'll experiment using an ice tomorrow and
putting a forever loop  in so I can see what this thing is doing, but
have any of you guys seen this before?

Another thing I don't quite get is that lpWriteDebugStringFunc is tied
to a function that send through the serial port - I monitor that using
a terminal program.
Isn't the debug screen of platform builder tied to the ethernet port
(UDP, I think)? Is perhaps what is normally routed to the serial
output switched somewhere to the ethernet port by the kernel? (does it
have that ability?)

Appreciate any input.
Regards,
Remco

5.KITL can't obtain IRQ for KITL device

Hi All,

I am trying to get the KITL to work through Serial Port on OMAP5910 based 
board.
The boot loader connects to the host and downloads the WinCE image fine,
but when the image boots and tries to connect through KITL it hangs and I am 
not sure why.

-------------------------------------------------
Here is the output from the serial debug log:

Nothing is shown in Platform Builder debug window, after it seems to hang.
Does anyone have any idea or similar experience?
