Hi Yanfeng Right now attributes like main memory are determined at compile time so if you want to change how much QEMU has you’d have to modify how Microkit compiles support for it. Here’s a patch that should work: ```patch diff --git a/build_sdk.py b/build_sdk.py index 2aefff6..aafc08c 100644 --- a/build_sdk.py +++ b/build_sdk.py @@ -208,11 +208,11 @@ SUPPORTED_BOARDS = ( name="qemu_virt_riscv64", arch=KernelArch.RISCV64, gcc_cpu=None, - loader_link_address=0x90000000, + loader_link_address=0x84000000, kernel_options={ "KernelPlatform": "qemu-riscv-virt", "KernelIsMCS": True, - "QEMU_MEMORY": "2048", + "QEMU_MEMORY": "128", "KernelRiscvExtD": True, "KernelRiscvExtF": True, }, ``` Ivan

Ivan,
Congratulations!
I am wondering if we use microkit on a QEMU riscv64 virt board with smaller memory size (like 128MB)?
Are there any notes about how to achieve this?
Regards, yf
