UART output garbled when building Litex SoC for CrossLinkNX with Radiant 2024.2

[polymerizedsage]

I am developing a Litex-based SoC my project girlvoice. I have been using Radiant 2023.2 for most of my development but recently updated to Radiant 2024.2. When building with the older version of Radiant the SoC boots and I get coherent UART output, however after updating to the newer toolchain, the UART output is garbled with invalid characters.

The design uses a custom PCB with a Lattice CrossLinkNX-17 72-pin QFN speed grade 8 device. I am using the latest version of Litex distributed on Pypi, which I believe is 2023.12. If it would be helpful I can post an example of the garbled boot output of the SoC
