Is swerv_eh1 core deprecated?

[jrmejiaa]

Hi all,

The rule swerv_setup is no longer working with the core Cores-VeeR-EH1 (previous SweRV). I saw that there is a fork of this core with the rule swerv_eh2_setup. This means that the rule and work of swerv_setup and swerv_pe is deprecated?

Thank you,

JM

SweRV EH1 support in tapasco-riscv is not deprecated. Please don't mix it up with the EH2, which is a different core. (Both have in common that the name was changed recently)

Even after the name change, the old locations should still work. What exactly is your issue with the SweRV?

The setup is not working as expected because of a mismatch in the patch. Maybe it is better to go to an specific commit and not to the master branch?

Without reproducing your problem (yet): Your finding seems correct. One could either check-out an older version of eh1, or adapt the patch for eh1.

Ah ok. They not just renamed the core but also the file names. Feel free to update the patch.

Hi, I cannot create a new fork just for this change, so I prefer not to make my own PR, but if you apply this patch, the core would work as expected with the last version of the master branch.

# From taspasco-riscv root folder
git apply fix_swerv.patch

Please let me know if this works also for you.
