Thanks for trying! Did you apply the patch to skip the DDR memory initialization mentioned in this page? https://wiki.qemu.org/Documentation/Platforms/RISCV#Microchip_PolarFire_SoC_Icicle_Kit > > I tried to build hss 3faaaaf8ce0d, using > https://github.com/riscv/riscv-gnu-toolchain (7f1f4ab5b0e0), which > ends up being a gcc 10.1.
