pyocd does not detect debug probe

[AILIFE4798]

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?

[AILIFE4798]

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

[windowsair]

If possible, could you provide more information about pyocd, such as the version you're using and related commands?

[AILIFE4798]

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

[windowsair]

I have reproduced the problem. It may take some time to adapt pyocd :)

[windowsair]

try this firmware

https://github.com/windowsair/wireless-esp8266-dap/actions/runs/7656753399

[AILIFE4798]

need change wifi credentials
ssid:AILIFE_SmartHome_2.4G
password:43214321
because i cannot build my self

[AILIFE4798]

ota also does not work

[windowsair]

Some of pyocd's usb operations don't seem to be well adapted. It may take a while to fix this.

[AILIFE4798]

ok

[windowsair]

Hello, you can try the latest code in the master branch. I've done a simple test using pyocd :)

[AILIFE4798]

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

[windowsair]

Sometimes usbip can cause BSOD. For your device, is it always unable to erase?

[AILIFE4798]

yes always hangs for a long time then says no ack received

[AILIFE4798]

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

[windowsair]

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?

[AILIFE4798]

it is doing something this time

[AILIFE4798]

also tested on stm32f103 the single most common and most cloned chip
it did not work either

[windowsair]

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.

[AILIFE4798]

dont have a f103rc now
or actually i do have one but it is locked and i want to keep it

[windowsair]

okay i found some problem. we should use 10MHz speed when we use esp8266.

pyocd erase -t stm32f103c8 --chip --frequency=10000000

[AILIFE4798]

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
