RV32IM softcore stalling on new versions of the toolchain. #1292

Closed HakamAtassi closed 1 year ago

HakamAtassi commented 1 year ago

A softcore used for a research project has seemed to stop functioning correctly after an update to the toolchain (not entirely sure which aspect of the toolchain). The issue is demonstrated by a stall in the RTL simulation after building and running the project using the latest version of the toolchain (but does not occur with older checkouts). Here is a useful thread regarding the issue:

Hope this is of use. Take care.

Hello, (I wrote the softcore) As I just mentioned in the issue you linked, there is a peculiarity in the way the softcore gets the start of the text segment (manually) as it was for research purposes. I plan to make it more consistent/automated, but this does not relate to the toolchain itself. Hope this helps, Best regards

You need to debug the issue with your core in order to narrow down what's going on/wrong. There really isn't much to go on in the linked thread. And there's nothing at all to indicate any issue/bug with the toolchain as far as I can see. In particular there's no standalone self-contained test case that illustrates a problem.

Hello. I stand corrected- there was a change in the compilation that required a change in the testbench but no real bug to be fixed. Thanks for the help. Take care
