I'm sorry to bother you, but there is some problems when i compiling the qemu-system-aarch64
the wrong code is:

Could you please help me about that?

Hello! I got an issue where I can't add remote memory. If I try to add remote memory, I get the following message:
ERROR:/<...>/avatar-qemu/qom/object.c:689:object_new_with_type: assertion failed: (type != NULL)

I am on the branch dev/qemu-5.1.

Working with 6.2, configurable machine, ARM Cortex-M. The problem I believe lies here:

The buf passed to banked_gdb_set_reg is a uint8_t * and this works correctly. However, the buf passed to banked_gdb_get_reg is actually a GByteArray *. The stl_p operation (eventually translated to a memcpy call) writes 4 bytes to the destination of the pointer... which is overwriting the pointer contained in the first member of the GByteArray structure and not actually storing to the byte array. Furthermore, it does not update the length field of the GByteArray. Shortly thereafter, qemu-system-arm terminates with a segmentation violation.

This is pretty easy to reproduce: start the emulator with an appropriate configuration, then (assuming gdb port 1234) connect with arm-none-eabi-gdb:

target remote :1234
info reg

The correct operation here is probably just gdb_get_reg32.

QEMU 4.2.0 will be released very soon, with a lot of improvements since 3.1.0 you use.

See the full Changelog, especially the TCG Plugins feature.
