Hello!
I am trying to make an SD card working on the sifive_u
(hw/riscv/sifive_u.c) SoC machine.
As far as I understand there is no way to connect an SD card to the SoC
with cmdline for now. So, I started to dig in to the QEMU internals and
especially sifive_u SoC implementation to try to understa

Thank you! It is worked!
Hello,
I am trying to debug the sifive_u SoC in the QEMU with GDB.
SiFive Unleashed contains one E51 core and four U54 cores.
In the hw/riscv/sifve_u.c E51 and U54 cores are placed in the different CPU
clusters.
In the gdbstub.c, it is searches only the first cluster and it always finds
cluster wi
