hi,

i have a Lauterbacher debugtool and a JTAG Inteface for a LPC4357.

Can i use LPCXpresse only for compiling and linking my code without sizelimitation of 256kByte for download?
Is this limitation only for download or also for compiled code?

Some other advice for a compiler? I prefer GNU but i also take a other one. If possible cheap or without costs.

Thx.

Georg.

The code size limit only applies to debugging with LPCXpresso. There is no code size limit on the generated code.

Now,

i have all my harware here and sarted with some examples. First with the CAN-driver from LPCOpen 2.09.
I can compile and link this project. I have connection to LCP4357 with my lauterbach debugger.

I need some help to change the linkerfile to link all the code to ram so i can debug it.

Have someone a small simple linkerfile for ram?
Or can someone help me to change the existing from "periph_ccan" driver?

thx.

Hi,

can one tell me how to change the linkerfile to link all the code to RAM?

I tryed to change the linkerfile but my changes are overwritten.

For example:

I changed all "MFlashA512" entrys with "RamLoc40" but after compiling the CAN-Driver
my changes were lost.

Is it possible to change this section pure and simple?

thx.

You need to use the memory configuration editor. For details, please read the LPCXpresso User Guide - in the IDE's built in help, or as PDF in the install directory.

Hi,

thx for your help.
Its now possible for me to link the code to ram.

I only need a correct debugg configuration to debugg with lauterbach.
Can anyone tell me how to config the LPC4357 to debug with it.
I think i have to set some µC registers.

My problem is that my firmware crashes if i debug it.
On every time if i try to read or to write a µC Register (for example RS232 Configuration of µC)
LPC5347 crashes and the PC (programm counter) stands on adress 0x1c000132.
I think i need some configuration in the AHB MULTILAYER MATRIX bevore i start to debug my firmware.

Can anyoune give mit some advices where to find more information about debugging?
For example how its done by Keil or LPCExpresso? Its enough if i have a script from a other debugtool.
So i can change my script for lauterbach TRACE32.

Thx.

Regards,
Georg.
