Compile target STM32L442 about solo1

[conorpp]

From targets/stm32l442, run

make cbor   # build cbor library
make           # build application

TODO:

I re-compiler tinycbor with arm-none-eabi-gcc

cd tinycbor
make CC=arm-none-eabi-gcc LDFLAGS="-specs=nosys.specs"

and rebuild targets/stm32l442

cd ../targets/stm32l442
make clean
make all

I got error:

I think you have to make clean at the parent level, and then make inside the stm32 target. It could definitely be improved :)

I have done this but I still got same error. I delete solo folder and re-clone project

git clone --recurse-submodules https://github.com/SoloKeysSec/solo
cd solo/
git submodule init
git submodule update

cd targets/stm32l442
make all

but I got error

/home/t-u/Tools/gcc-arm-none-eabi/bin/../lib/gcc/arm-none-eabi/5.4.1/../../../../arm-none-eabi/bin/ld: cannot find -ltinycbor
collect2: error: ld returned 1 exit status
Makefile:65: recipe for target 'solo.elf' failed
make: *** [solo.elf] Error 1

because tinycbor is not builded
I build tinycbor with arm-none-eabi-gcc as I said above

cd ,,/,,/tinycbor
make CC=arm-none-eabi-gcc LDFLAGS="-specs=nosys.specs"

and rebuild targets/stm32l442

cd ../targets/stm32l442
make clean
make all

but still error

@conorpp Thank for your reply.
T follow your command but I still got error: error: required section '.rel.plt' not found in the linker script
I search this error on google and see many people got it (most expected in embedded projects, cross-compile) but I don't see any answer.
Do I miss something?

[nvti]

oh, I got a little error:

../../crypto/sha256/sha256.c:17:20: fatal error: memory.h: No such file or directory
 #include <memory.h>
                    ^
compilation terminated.

but I fix it by commend #include <memory.h> line in crypto/sha256/sha256.c file.
Does it have any effect to above error?

About my tool chain:
I download tool chain and use this

$ arm-none-eabi-gcc --version

Finally, I change my compiler to version 7.3.1 (download) and no more error
