Thank you for the reply.
We are getting undef instruction error as soon as the control hits start of the program.
Below are the build settings we have followed using the S32DS_Power_Win32_v2.1 compiler:
1.Compiled the code using '-powerpc-eabivle-gcc-4.9.4' compiler located in "\nxp\S32DS_Power_v2.1\S32DS\build_tools\powerpc-eabivle-4_9\bin" with change in target flags to support VLE instruction set
TGT_FLAGS = -mno-eabi -memb -mabi=spe -mregnames -Wa,-mregnames -Wa,-mvle -misel -Wa,-me500 \
-mspe -mfloat-gprs=single -mhard-float -mlra
2. To support VLE instruction set extension and to execute code in VLE page, we have set VLE bit to 1 in the MAS 626 register as part of MMU for flash and SRAM TLBs.
3. Below are the updates done in compiler settings to use the powerpc-eabivle-gcc-4.9.4
PREFIX = C:\nxp\S32DS_Power_v2.1\S32DS\build_tools\powerpc-eabivle-4_9\bin
CC = $(PREFIX)\powerpc-eabivle-gcc
CPP= $(PREFIX)\powerpc-eabivle-g++
AS = $(PREFIX)\powerpc-eabivle-as
AR = $(PREFIX)\powerpc-eabivle-ar
LD = $(PREFIX)\powerpc-eabivle-ld
NM = $(PREFIX)\powerpc-eabipse-nm
OBJDUMP = $(PREFIX)\powerpc-eabivle-objdump
OBJCOPY = $(PREFIX)\powerpc-eabivle-objcopy
READELF = $(PREFIX)\powerpc-eabivle-readelf
Please provide your support to fix the aforementioned issue. Kindly, let us know if you need more information.
Thank you for the response. Sorry for the delay.
We tried to use the flags suggested in the previous response.
We modified the C, CPP and Assembly compiler flags using the S32 design studio environment as reference.
Assembly files do not compile and throw unrecognized opcode, if -me500 flag is not used, as shown in below image:
So, we added -me500 flag in our compilation. Below are the assembly flags:
"ASFLAGS = -g3 -mbig -mregnames -me500"
For C and CPP files, we added -mcpu=e200z7 and -meabi as suggested in the previous response. We removed -mfloat-gprs=single, -memb and -mlra
For C files below are the compiler flags:
CFLAGS = -meabi -mabi=spe -mregnames -Wa,-mregnames -Wa,-mbooke32 -misel \
-mspe -mhard-float -O0 -g3 -Wall -c -fmessage-length=0 -fstrict-volatile-bitfields -ffunction-sections \
-fdata-sections -mcpu=e200z7 -mbig -mvle -mregnames -mhard-float -std=gnu99\
For CPP flags below are the compiler flags:
CPPFLAGS = -meabi -Wa,-mregnames -misel \
-mspe -mhard-float -O0 -g3 -Wall -c -fmessage-length=0 -fstrict-volatile-bitfields -ffunction-sections \
-fdata-sections -mcpu=e200z7 -mbig -mvle -mregnames -mhard-float \
-fno-default-inline --param max-inline-insns-auto=0 -fno-inline-functions \
-fno-rtti -fno-exceptions -fno-enforce-eh-specs -fno-builtin -fno-threadsafe-statics -fno-gnu-keywords \
-fno-nonansi-builtins -fno-operator-names -nostdinc++ -Wabi -Wreorder -Woverloaded-virtual -Wsign-promo -Winit-self \
-Wswitch-enum -Wextra -Wfloat-equal -Wunreachable-code -fsingle-precision-constant \
Below are the linker flags used:
"LDFLAGS = -EB -N -v --gc-sections --sort-section alignment -warn-common"
After setting the above compilation flags. We are still getting undefined instruction error, while execution. Please check the below diagram.
Please help us to resolve the above issue. Kindly let us know if more information is needed,
Thanks!
Even after successful compilation and linking .cpp object code has instruction undefined.
Hello,
I've tested to compile a startup asm. source file (attached) with the option -me500 and I cannot event compile it. I get error below:
powerpc-eabivle-gcc.exe: error: unrecognized command line option '-me500'
With the options:
-c
-g3
-mbig
-mregnames
-meabi
-mcpu=e200z7
i can compile asm file even with evxor instruction:
it is not correctly disassembled however the opcode seems to be ok.
Could you possibly post your assembler outpu tbuild console when -mcpu=e200z7 option is used instead of
-me500.
Could you also turn on verbosed more by adding -v opton. This will provide us with some additional details.
Thanks,
Stan
