Hi All,

I am now in the need for a real time kernel and interested in porting
FreeRTOS to LPC2888, but until now still has not succeeded, but in the mean
time I found out that a real time kernel (ARM-RTX) was included in my Keil
MDK license,

As the kernel bundled with the MDK does not come with the source code and
all the examples are built for LPC2129, LPC2103 and LPC2138,
is it possible to use the kernel on LPC2888 without having the source code?

Actually I tried to compile the kernel for LPC2888, but as soon as I changed
the header file for LPC21xx.h with LPC288x.h, there are some unidentified
identifier, which I think was a platform specific identifier, like:

> RTX_Config.c(242): error: #20: identifier "T1IR" is undefined
> RTX_Config.c(242): error: #20: identifier "VICSoftIntClr" is undefined
> RTX_Config.c(242): error: #20: identifier "VICVectAddr" is undefined
>
which came from a function named OS_TIACK();

> RTX_Config.c(265): error: #20: identifier "T1MR0" is undefined
> RTX_Config.c(265): error: #20: identifier "T1MCR" is undefined
> RTX_Config.c(265): error: #20: identifier "T1TCR" is undefined
> RTX_Config.c(265): error: #20: identifier "VICDefVectAddr" is undefined
> RTX_Config.c(265): error: #20: identifier "VICVectAddr15" is undefined
> RTX_Config.c(265): error: #20: identifier "VICVectCntl15" is undefined
>
which came from a function named OS_TINIT();

The problem is I can't do modification because I can't find those identifier
in the files supplied with the Keil MDK.
Kind Regards,

There are very few modifications required to move from one ARM7 to another.

+ Check the linker script is correct.
+ Check the startup code allocates stacks for IRQ and Supervisor modes as a
minimum.
+ Check the startup code calls main() from Supervisor mode.
+ Check prvSetupTimerInterrupt() in port.c uses a timer that is available on
the LPC2888 device.

Hi,

Basically most of the undefinded #defines could be added easily. Keil
tends to rename the common registers from family to family a bit
different, which is very uncomfortable, but others do the same :-(

But when you do not have the sources, adding the #defines only will
not help, as the way interrups are working is different on LPC2888
and LPC2138. I assume that the latest version of ARM-RTX *will*
support the LPC2888 as well.

Hello,

Yes, you are right,
I can't just exchange the LPC21xx.h with LPC288x.h on RTX_Config.c but I
need a really different RTX_Config.c
But does Keil provide us with that configuration file?
Kind Regards,
Widita

Hi,

In deed, The ARM-RTX I used is quite old,
* Name: RTX_CONFIG.C
* Purpose: Configuration of RTX Kernel for Philips LPC21xx
* Rev.: V3.04 / 10-jan-2007

Has anyone used ARM-RTX from newer RTX Kernel on LPC2888?

Kind Regards,
Widita

Hi,

I asked for the RTX_Config.c from keil official support, but they don't have
a specific RTX_Config.c for LPC2888,
And I tried to change the configuration by myself,

But I am confused with some definitions:

1. #define OS_TOVF (TIMx(IR) & 1) /* Overflow
Flag */
Because I can't find where I can read the overflow flag on LPC2888 timer
2. #define OS_TIACK()
VICVectAddr = 0;
Because I can't find the replacement register for VICVectAddr on LPC2888
interrupt controller
3. VICDefVectAddr = (U32)os_def_interrupt;
Because I can't find the replacement register for VICDefVectAddr on
LPC2888 interrupt controller
4. And I am troubled in assigning the ISR handler for the Timer Interrupt

It turns out that the timer and interrupt controller differs greatly between
LPC21xx and LPC288x series.

Can someone please help me finishing this configuration file?
Thanks
Regards,
Widita

Hi Richard,
I tried to convert the demo project "ARM7_LPC2129_Keil", and it seems there
is something wrong with the portmacro.h, it can't be compiled...

here is the compilation error messages:

Build target 'LPC2888'
assembling Startup.s...
compiling main.c...
..\..\Source\include\..\..\Source\portable\Keil\ARM7\portmacro.h(112):
error: #52: expected a macro parameter name

portmacro.h line 112:
__asm{ LDR LR, [LR, #+60] }; /* Restore the return address. */
\
And here is the IDE-Version of my Keil UV3

My question is, are we using different compiler? because it seems that those
errors is shown because of the compiler is treating the code differently?
and indeed, when I tried to compile using the original project file
(rtosdemo_ARM.Uv2), it said about cannot find the compiler.

What should I do to compile these project files?
Thanks in advance,
Regards,
Widita
