Hi,
i am using the AMbiqSDK and apollo3 BSPs git from sparkfun (updated), and i copied the files from the folder ../boards/apollo3_evb/examples/ble_freertos_amdtps into the ../AMbiqSuiteSDK/boards_sfe/artemis_thing_plus_examples/ble_freertos_amdtps folder. I updated the Makefile file and, using the asb_linker script, the following error appears when executing make:

Code: Select all

...
Compiling gcc startup_gcc.c
 Linking gcc bin/ble_freertos_amdtps_asb.axf with script ../../../../common/tools_sfe/templates/asb_linker.ld

collect2.exe: error: ld returned 1 exit status
make: *** [Makefile:319: bin/ble_freertos_amdtps_asb.axf] Error 1

The lines from the Makefile related to the asb_linker are the following:

Code: Select all

$(CONFIG)/$(TARGET)_asb.axf: LINKER_FILE = ../../../../common/tools_sfe/templates/asb_linker.ld 
$(CONFIG)/$(TARGET)_asb.axf: $(OBJS) $(LIBS)
	@echo " Linking $(COMPILERNAME) $@ with script $(LINKER_FILE)";\
	$(CC) -Wl,-T,$(LINKER_FILE) -o $@ $(OBJS) $(LFLAGS)

However, in case I comment the line

Code: Select all

$(CONFIG)/$(TARGET)_asb.axf: LINKER_FILE = ../../../../common/tools_sfe/templates/asb_linker.ld 

it makes successfully ... so what's the problem in orde to execute the ble_freertos_amdtps in my artemis thing plus board?.
Thanks

for what its worth: From Working amdtps makefile for Nano....

Hi @KHE, which linker script are you using, asb_linker.ld or ./ble_freertos_amdtps.ld ?. Could you please share the last lines when you make the ble_freertos_amdtps example using this Makefile? Thanks

[KHE]

sorry..didn't get email regarding request...here is output from end of compile...

Hi there guys - you are probably aware of this post: viewtopic.php?f=168&t=51993

As for linkers... In the working freertos example I chose to use the original linker script from the Apollo3 EVB. For the SVL the only modification required was to change the offset of FLASH memory to 0x10000 (from 0xC000)

[fbtobajas]

Hi @liquid.soulder ... in case i copy the original linker script from the ble_cordio_tag example folder for Apollo3 EVB , and i modified it according to your post, it get compiled, linked and uploaded successfully by using make bootload_svl. Great! ... however, in case i use the asb_svl_linker.ld script from boards_sfe/common/tools_sfe/templates/asb_svl_linker.ld, it fails and the following error is reported:

Code: Select all

make: *** [Makefile:444: ../gcc/bin/ble_cordio_tag_svl.axf] Error 1

Does it make sense to you? ... can the asb_linker.ld / asb_svl_linker.ld files provided into the boards_sfe folder have some error?. Thanks for your help!

Makefile.txt

I was successful (after 2 full days) of moving the amdtps example from the new SDK 2.3 to boards_sfe using liquid's new makefile strategy. I basically modified the tag makefile a little to create the attached makefile. Here are the steps and the makefile will be attached with .txt on end (as I can't figure out how to upload file with no extension):

AMSDK example to Spark Fun boards_sfe conversion
1) Copy ble_freertos_amdtps directory from SDK/boards/apollo3_evb/examples/ to SDK/boards_sfe/common/examples
2) SDK/boards_sfe/common/examples/ble_freertos_amdtps delete iar and keil directories
3) SDK/boards_sfe/common/examples/ble_freertos_tag/gcc copy ble_freertos_tag_asb.ld and ble_freertos_tag_svl.ld to the SDK/boards_sfe/common/examples/ble_freertos_amdtps /gcc directory.
4) Download attached Makefile (rename to remove .txt extension) and replace SDK/boards_sfe/common/examples/ble_freertos_amdtps /gcc/Makefile with this downloaded Makefile.
5) From git bash terminal cd to SDK/boards_sfe/common/examples/ble_freertos_amdtps/gcc
6) For example edge2 board: type EDGE=edge2
7) type make BOARD=$EDGE
8) will compile to final copy to bin with last line looking like:
Copying gcc ../gcc/edge2/bin/ble_freertos_amdtps_asb.bin...
9) make BOARD=EEDGE bootload_svl will load the board if on COM4 (change in Makefile)
10) if problem with bootload_svl, try bootload_asb. If ever successful with booload_svl, may need to reset board in Arduino with Tools / Burn Bootloader (Programmer: Ambiq Secure Bootloader)

oops...#9 should be BOARD=$EDGE not EEDGE..sorry

[fbtobajas]

Hi @KHE, thanks a lot for your help & support. As soon as i can check it, i will post my results. Thanks.

[KHE]

opps again...#10 should be: if ever successful with bootload_asb ...

[fbtobajas]

Hi @KHE, just an small change. In step 3), it is requierd to rename the file ble_freertos_tag_asb.ld to ble_freertos_amtdps_asb.ld, and the file ble_freertos_tag_svl.ld to ble_freertos_amtdps_svl.ld . I've checked it, and following the steps you provide, i successfully made ble_freertos_amtpds example work in my artemis thing plus board. Thanks!

[KHE]

oops #3..good thing I'm not a banker....Thank you fbtobajas

so with corrections...

MAY HAVE TO RENAME BOARD DIRECTORY NAME TO REMOVE UNDERSCORES...

FYI ... Link Problem with redboard_artemis_nano: compiled but wouldn’t link ‘till renamed boards_sfe/redboard_artemis_nano directory to boards/sfe/nano, then it worked fine.

Underscores causing the problem. I renamed board directory to 123456789012345678901 and it worked . 12345678_9012345_6789 had the same error.therefore underscore problem, not length.

Error when NANO=redboard_artemis_nano was used:
