Porting a Keil uVision project to the GNU tool chain

Hello Mohit,

our GNU expert is OOO this week and admittedly I dont have much experience of GNU myself. I did a quick search online : can .obj files be linked in GNU ? this thread belwo implies not.

Hi,

I ve got the same result, can not advertise when I compile with this toolchain gcc-arm-none-eabi-4_8-2014q3. However I can run come code (ie. led blinking) and its working.
I can also confirm that the uart driver is not working with that tool chain. I used the conversion script to generate the Makefile. I did also some test with the DA14580_BEACON_3.40-2.6 sample code with no luck.

Whatever sample code I use when I set cmd->channel_map to anything but zero I seems to crash the module...

Any idea ?

I can confirm that -fplugin=tree_switch_shortcut_elf is not compatible with windows & mac version of gcc-arm-none-eabi-4_8-2014q3, but only on linux. I did not try on a linux box with with option (I'm compiling on a mac.)

Here is my Makefile for further info :
#
# The Makefile must define the following variables, which are used by common.mk:
# O: output directory
# STACK_SIZE: number of bytes to reserve for the stack
# HEAP_SIZE: number of bytes to reserve for the heap
# CORTEX_M: the Cortex-M model to target
# STARTUP_DEFS: define's that configure the start-up code
# CFLAGS: flags used for compilation AND linking
# LDFLAGS: flags used for linking
# ROM_MAP_FILE:ROM map file
# OBJ: list of object files to compile and link
# TARGET_ELF: name of the target (used in the generated images)
#

# output directory
O ?= out

# stack size
STACK_SIZE = 0x0600
# heap size
HEAP_SIZE = 0x0100

# Startup code
CORTEX_M := 0
STARTUP = startup_ARMCM$(CORTEX_M).S

# startup configuration

I managed to compile with the 'tree_switch_elf' option using GCC 4.9 for mac,https://launchpad.net/gcc-arm-embedded/4.9. I make this change in the Makefile :

# optimisation flags
CFLAGS += -Os -ftree-switch-shortcut

没有路ck, same crash on the module as soon as I use cmd->channel_map to select one channel for broadcast..

Is there any chance to have an update on this project like having a full configured working project using the radio (including Makefile & updated linker script) using GNU GCC please ?

Any help on this subject will be much appreciated !

谢谢:)

Hi,

Has there been any update yet?

Reading the App note B-024 seems to imply that the project builds and works, has someone gotten the radio to work with the gcc tool chain yet?

Thanks

The solution is to use this toolchain:
https://launchpad.net/gcc-arm-embedded/4.9/4.9-2015-q3-update
and change the -fplugin=tree_switch_shortcut_elf into -ftree-switch-shortcut

Possibly you'll get the next error about __weak, solve that by adding -D__weak="__attribute__((weak))" to the CFLAGS in common.mk
And an error about __nop(), solve that by adding -D"__nop()"="asm(\"NOP\")"
