pyocd does not detect debug probe
esp8266 version worked just fine with usbip on keil i can upload and debug
but i want to erase flash to unlock readout protection with pyocd but it does not detect the debug probe
Hi, @AILIFE4798 ,
I haven't tested pyocd. Can the device be detected if you use openocd?
idk how to use openocd , and it does not support the mm32spin05pf mcu i need it for
the device is detected in device manager correctly like in the readme
If possible, could you provide more information about pyocd, such as the version you're using and related commands?
i installed the latest pyocd with pip
just install python first (ofcourse) then use pip install pyocd(vpn needed)
then to check the available debug probe use pyocd list -p it should show the probes like this
try this firmware

need change wifi credentials ssid:AILIFE_SmartHome_2.4G password:43214321 because i cannot build my self
Some of pyocd's usb operations don't seem to be well adapted. It may take a while to fix this.
Hello, you can try the latest code in the master branch. I've done a simple test using pyocd :)
i have tried to use latest firmware
it can detect the probe now
but cannot erase or flash
when a target is connected correctly it says no ack received
and when i didnt connect target it says unexpected ack value 0
and there is suvior bug idk in where
cuz when i first tried this i connected the swd line wrong and when i run erase command it hangs for 30 second and entire windows os crashed with blue screen
it hapenned 2 times
but it is not consistant i cannot reproduce it
Sometimes usbip can cause BSOD. For your device, is it always unable to erase?
usb ip on windows is really not easy maybe better way is to upload hex or bin file via a website and itll get flashed to device or maybe gdb server via wifi
Well, I don't have too many chips to test. Looks like you have mm32 and gd32 boards? If you use the gd32, will it work?
also tested on stm32f103 the single most common and most cloned chip
it did not work either
It's weird. looks like the behavior is the same between the different chips. I tested it on stm32f103rc and it work well :( I'll try c8 later.
dont have a f103rc now or actually i do have one but it is locked and i want to keep it
okay i found some problem. we should use 10MHz speed when we use esp8266.
pyocd erase -t stm32f103c8 --chip --frequency=10000000
ok it seems to work now
i wished i have this earlier so i do not need to spend a day to solder serial wire to mcu and flash it that way
