And I can create 3 RAM section for avoid exeption handler! Maybe any
devices from this adress does not appear in qemu...

Title:
QEMU arm virt machine was stopped by STMFD command while debug process
Status in QEMU:
New
Bug description:
Hello, i have a big problem with QEMU arm virtual machine. So...
I run QEMU machine with bare-metal ThreadX fullflash from Texet TM-333 phone
(Spreadtrum platform)
[CODE]qemu-system-arm -S -gdb tcp::1234,ipv4 -drive
file=C:\cygwin64\home\flash.bin,if=mtd,format=raw -M palmetto-bmc -cpu arm926
-m 64M[/CODE]
I use palmetto-bmc platform because it have ARM926EJ-S core and support SPI
Flash.
Then, i attach to gdb qemu process from IDA and run code step-by-step.
When the IDA run 00032534 STR R11, [R10] command
instead of store R11 on R10 adress, it jump 000328DC STMFD SP!, {R0-R12,LR}
instruction...
and virt machine not execute new instruction...
[IMG]https://pp.userapi.com/c850624/v850624111/528f3/N7FTpgloWVU.jpg[/IMG]
and why i did not change flash from n25q256a to n25q032a11 in aspeed.c
without rebuild qemu?
