qemu error zephyr-synchronization

[umairsiddiqui-digitek]

hi,
i am trying to run the zephyr-synchronization project on VScode platformio IDE for
QEMU Sifive Hifive 1 board

i copied the zephyr-synchronization from this repo and modified my platformio.ini

[env:hifive1]
platform = sifive
framework = zephyr
board = hifive1
debug_tool = qemu

but i am getting following errors...

Preparing firmware for debugging...

Hi @umairsiddiqui-digitek ! Thanks for the report. Looks like it's an internal error in SiFive SoC implementation in RISC-V QEMU, do you have this board at hand by any chance?
