micropython

[bittu-digital]

I found that you are working on ztachip.I got issues with the micropython
I have done the ztachip build process , standalone image is working fine.
While going with micro-python ,I followed these steps
git clone https://github.com/micropython/micropython.git
cd micropython/ports
cp -avr /micropython/ztachip_port .
cd ztachip_port
export PATH=/opt/riscv/bin:$PATH
export ZTACHIP=<given the path , where zta-chip is built>.
make clean
make
But the error i got is same again after "make"

Even while opening minicom using " sudo minicom -w -D /dev/ttyUSB1" i could not open any prompt to paste the example codes.
Resolving this issue will be very grateful to me

@bittu-digital
There's something (ztachip installation folder) missing in the list of commands you provided
Please follow this as it is

git clone https://github.com/micropython/micropython.git
cd micropython/ports
cp -avr <ztachip installation folder>/micropython/ztachip_port .
cd ztachip_port
export PATH=/opt/riscv/bin:$PATH
export ZTACHIP=<ztachip installation folder>
make clean
make

Also, I think you're using you host machine's GCC to compile. Make sure this line points to the riscv compile that supports 32-bit RISC-V ARCH and ABI in your host machine. if you're unsure, you may check it with the following command.

$ riscv64-unknown-elf-gcc -print-multi-lib
