Summary

      I recently bought a stack of puya py32 mcu’s after reading this article

       I’ve been testing them out using the SDK here

       I noticed that many of my daplinks and other probes fail to connect
       to this mcu with pyocd [and openocd, though I didn’t test it as
       thoroughly] when using the pack file provided by the vendor here

       I have a stack of different probes and mcu’s running daplink
       firmwares, and only one of them works OK. Most of the
       daplinks fail with:

pyocd.core.exceptions.TransferError: Unexpected ACK value (5) returned by probe

Method

      To ensure the probes are working OK, I tested each on an STM32F103C8
      mcu, as well as with a Puya PY32F002AL15. I figured the STM should be a
      good control test, as it’s a very well supported and commonplace mature
      product.

      I’m running pycod 0.34.3.dev36 – though I did also test .34.3 release as
      well with identical results.

      My OS is Ubuntu lunar (dev), on linux 5.18.13

      I prepared a firmware for each mcu, and programmed it with the following
      commands:

STM32:

$ pyocd erase --chip -t stm32f103c8; pyocd load -t stm32f103c8 ./miniblink.bin

PY32:

$ pyocd load ./Build/example-blink.hex -t py32f002x5 --config ./Misc/pyocd.yaml

      (the config file simply loads the pack file from the vendor)

$ cat pyocd.yaml
pack:
\- Misc/Puya.PY32F0xx_DFP.1.1.3.pack

Something I just discovered: programming works better at 3V3 Vcc. At least some of the probes that weren't working for me actually DO work, but only when running the PY32 at 3.3V. And all probes seem to work with more stability and reliability at 3.3V

@prosper00 I'm having the exact same problem. which programmers did you use to connect?
the vendor mentions a py-link programer which seems like a modified jlink but I couldn't find it anywhere.

I have a st-linkvs but I can't connect to it using neither stlink nor dap link.

any of the jlinks generally work, but only when the target is on 3.3V

@prosper00 would a clone Jlink OB work as well? like this one

I have used this board with success: Air32F103CBT6
https://www.aliexpress.com/item/1005004635091721.html

With the air32_daplink_v1.hex , from the below
https://gitee.com/openLuat/luatos-soc-air32f103/tree/master/AIR_Jlink_Keil

I couldn't get the "new" v2 firmware to work.
https://www.eevblog.com/forum/microcontrollers/air105-air32f103-new-chinese-arm-chips/msg5014411/#msg5014411

I programmed the Air32 w. a jlink , specifying taget as : STM32F103CB

I was attempted to flash a Puya PY32F003 on the official development board (PY32F003F18P EVB) with a DAPLink (no brand on it), and got Unexpected ACK value (5). In my case, this was fixed when I plugged in the USB-C. In addition to having 3.3V connected on the DAPLink connector (which I thought would be enough?).
Just thought I would mention it, in case it can save someone else some time :) It was a rather unintuitive error for this case...
