Hello Folks,
I need some help to understand how it is possible to write "myappl.axf" file to external memory program to LPC4350FET256. I use the Code Red Suite and external memory is Spansion (S25FL208K0RMFI010).

The "myappl.axf" is the binary application that was generate with Code Red Suite Compiler.

I realy appreciate if somebody suggest a schematic for hardware and piece of code to do that.

Thanks in advance.

Hi oprata,

LPCXpresso and Red Suite ship with example projects that program code to external QSPI. In LPCXpresso, they should be located in:
C:\nxp\LPCXpresso_xxxx\lpcxpresso\Examples\FlashDrivers\NXP\LPC18xx_43xx\LPC18xx_43xx_SPIFI.zip

Hello Folks,
I am trying to run dual core application for LPC4350FET256 processor. I created a example for dual-core at LPCXpress version 7.4. But when I tried compile the code I saw a problem:

Building target: IPC_M4.axf
Invoking: MCU C++ Linker
arm-none-eabi-c++ -nostdlib -L"D:\oscavo\Documents\RedSuite_5.2.6_2137\CMSIS_LPC43xx_DriverLib\Debug" -L"D:\oscavo\Documents\RedSuite_5.2.6_2137\CMSIS_DSPLIB_CM4\lib" -Xlinker -Map="IPC_M4.map" -Xlinker --gc-sections -mcpu=cortex-m4 -mfpu=fpv4-sp-d16 -mfloat-abi=softfp -mthumb -T "IPC_M4_Debug.ld" -o "IPC_M4.axf" ./src/IPC_M4.o ./src/cr_cpp_config.o ./src/cr_start_m0.o ./src/cr_startup_lpc43xx.o ./src/crp.o

collect2.exe: error: ld returned 1 exit status
make: *** [IPC_M4.axf] Error 1

Does anybody know what is happening?
Thanks in advance.
