RemoteMemoryRead failed: Failed to read memory! about avatar2-examples HOT 7 OPEN

Hi, this issue was described already here: #4

Albeit closed, it has the answer for you: Everything worked as expected, you arrive at Arrived at main loop, demo is over .

The issue is in the avatar2 teardown. Have you tried running the script unbuffered (python3 -u qemu_uboot_avatar2.py)? Maybe it fixes at least the race condition between logging and throwing of the exception.

It's the same result of running python3 -u qemu_uboot_avatar2.py . But why do I get an error when I try to read the value of memory or register?

Heya, taking a second loop at the timestamps, and may indeed be the case that QEMU errors straight-away. Can you retry with the PANDA target for the time being, instead of the qemu target? I think something may have gone wrong during our yearly sync with upstream qemu, resulting into these errors.

Hi,

There is more debugging info within /tmp/myavatar directory. What is the output of cat /tmp/myavatar/{QemuTarget0_err.txt,QemuTarget0_out.txt}?

from avatar2-examples.

cat QemuTarget0_err.tx
qemu-system-arm: RemoteMemoryRead failed (-1)!

Well, my current goal is to simulate the stm32 development board, so I didn't consider using Panda.

from avatar2-examples.

Panda is under the hood qemu based, and is currently more used by the avatar2-developers (and, hence, better testing).
Additionally, the framework can serve as drop-in for Qemu! Please try:

AVATAR2_QEMU_EXECUTABLE=panda-system-arm python3 qemu_uboot_avatar2.py

(assuming you are in the docker or have panda installed locally.)
