[SOLVED] Linker throws "cannot find default versions of the ISA extension `i'" for RV32E

ricardo_nunez · Jul 29th 2022, 4:01pm

When generating code for RV32E we get this error:
cannot find default versions of the ISA extension `i'

The assembler and compiler are set to be gcc.

I found the issue is reported also here:

github.com/riscv-collab/riscv-binutils-gdb/issues/261
sourceware.org/git/?p=binutils…f1995608fbf6648fcee4e9e0c
According to them, it seems the problem was likely introduced in "Bump Binutils to 2.36.1".

Now, it seems the issue has been fixed by the maintainers here:
github.com/riscv-collab/riscv-binutils-gdb/pull/262

but I still get the error in the SES for RISC-V last version (6.32)

Hello,

Thank you for your inquiry.
Such an issue is not known to us.

The reported behaviour was not reproducible for me with V6.32a.
Could you give that version a try?
If the issue persists, could you provide a simple example project that shows the behaviour for reproduction?

Best regards,
Nino

Hi,
just using the "Hello world" example provided by default and using the following project options:
Assembler: gcc
Compiler: gcc
Linker: GNU

In SES V6.32a

Hello,

we will check the default sample. But this sample is meant to be used only to get a feeling on how Embedded Studio works. It is possible that it will not cover all use cases automatically.
If you plan on testing more features that are even architecture specific we recommend to create a new project with the project generator for the exact device or coretype that you are looking for to avoid exactly such issues.

Best regards,
Nino
