I am unable to program the SOP8 PY32F002AL15S6TU. using the board "Generic PY32F002A Series"

I tested the usb to serial connected to PA1-PA2 and PA2-PA3 for serial port ,but I am unable to program the chip from arduino 2.0 with this core.

this is the error I get:

WARNING: library SrcWrapper claims to run on AirMCU architecture(s) and may be incompatible with your current board which runs on PY32 architecture(s).
Sketch uses 6292 bytes (30%) of program storage space. Maximum is 20480 bytes.
Global variables use 808 bytes (26%) of dynamic memory, leaving 2264 bytes for local variables. Maximum is 3072 bytes.
AirISP v1.2.8.0
Serial port /dev/ttyUSB0
Connect...___
fail to reset device to boot status, timeout, exit...
Failed uploading: uploading error: exit status 1

Is there a Pin to drive to ground or VCC to program the chip? there is no BOOT0 or BOOT1 in this chip.

There is no option to add an STlink programmer to use PA14/PA13 for SWD protocol.

描述您想要的解决方案 / Describe the solution you'd like

Please provide a diagram of connections to program the chip, or instructions how to program it
or add an STlink programmer ,thank you.

描述您想要的详细使用步骤描述 / Describe the solution you'd like to use in what way

To be able to select a STlink programmer in the arduino menu or to use the serial connection when the connections diagram or instructions are provided.

and the PDF where I got the pinout https://datasheet.lcsc.com/lcsc/2303271200_PUYA--PY32F002AL15S6TU_C5292060.pdf
can this SOP8 or the SOP16 be programmed with this core?
Thanks in advance

I'm sorry I'm just now seeing the email because of the holidays.

In some packages of the PY32, there may not be a pin for accessing the ISP and programming with the UART, so in later releases we will consider adding SWD programming to cater for such scenarios.

For now, you can export the compiled binary and program it using one of the other supported methods, such as openocd pyocd, etc.

No worries and thanks for your reply.
In case you decide to implement the support for SWD programming with ST-link , this is what worked for me with pyocd and the SOP8 chip that I mentioned above (this works as well for the SOP16 PY32F002AW15S version):

pyocd load ./Blink.ino.hex -t py32f002ax5 --config ./pyocd.yaml
0000469 I Loading /home/user/Descargas/PUYA-SEMI PY32F002/PY32Duino.PY32.GenF002Acompiled/Blink.ino.hex [load_cmd]
[==================================================] 100%
0002038 I Erased 12288 bytes (3 sectors), programmed 9088 bytes (71 pages), skipped 0 bytes (0 pages) at 5.68 kB/s [loader]

and the content of the config file being listed with command cat pyocd.yaml
pack:
" - ./Puya.PY32F0xx_DFP.1.1.0.pack" <<<please remove the "" characters , otherwise the - gets edited as a bullet point

That file "Puya.PY32F0xx_DFP.1.1.0.pack" comes from this rar file: https://www.puyasemi.com/uploadfiles/2022/11/PY-MCU%E8%B5%84%E6%96%99-20221117.rar

Install pyocd with:
python3 -mpip install -U pyocd
Useful commands:

pyocd erase --chip -t py32f002ax5 --config /HERE-GOES-THE-FOLDER-WHERE-YOU-PUT-THE-FILE/pyocd.yaml

pyocd load -t py32f002ax5 --config /HERE-GOES-THE-FOLDER-WHERE-YOU-PUT-THE-FILE/pyocd.yaml ./*.hex
