CMSIS DAP drivers windows and PyOCD #15

Closed sabas1080 closed 3 years ago

sabas1080 commented 4 years ago

Hi @DeqingSun

I am testing CMISIS DAP with pyOCD with pyocd list and and i see it

Captura de Pantalla 2020-08-29 a la(s) 14 48 10

but I have a error

pyocd gdbserver -t nrf52840

this is in Mac with https://github.com/mbedmicro/pyOCD

Dapjs https://github.com/ARMmbed/dapjs

En Windows with Keli bf8cd5bd-1555-4a4b-a7a4-84da6503e5d3

Do you have any guide on how to use it?

DeqingSun commented 4 years ago

I haven't fully tested it with different software. But it worked well with the openocd from Arduino package

sabas1080 commented 4 years ago

Thanks @DeqingSun work en openocd

DeqingSun commented 3 years ago

Try https://github.com/DeqingSun/ch55xduino/tree/playground/ch55xduino/ch55x/libraries/Generic_Examples/examples/05.USB/CMSIS_DAP

And this should work. If you get it work, or not. Please let me know.

Not sure why it doesn't work with pyocd. It did work with Keil.

sabas1080 commented 3 years ago

I'm going to try with keil

sabas1080 commented 3 years ago

I was tried in

and not work for me, any special configuration? thanks

DeqingSun commented 3 years ago

I don't have any special configuration. It just worked in Win7.

I also am having problems with pyOCD 0.28.3. pyOCD list shows the adapter, but trying connect to a target always fails.

Looking at pyocd/probe/pydapaccess/cmsis_dap_core.py indicates it didn't receive a 0 (Command.DAP_INFO) in the first byte of the response:

        if resp[0] != Command.DAP_INFO:
            # Response is to a different command
            raise DAPAccessIntf.DeviceError("expected DAP_INFO")

However looking at the CMSIS_DAP example, I haven't found a bug. I've compared it to the DAPLink source, and although the CH55x DAP example doesn't implement many of the DAP_INFO commands, it copies the command from the request to the response just like the official firmware. https://github.com/ARMmbed/DAPLink/blob/master/source/daplink/cmsis-dap/DAP.c

I also get the same error under Linux (Ubuntu 18.04). pyocd.probe.pydapaccess.dap_access_api.DAPAccessIntf.DeviceError: expected DAP_INFO

DeqingSun commented 3 years ago

@nerdralph Did you get the code from the Arduino installer? For some reason it seems the code was not updated in the release package. Will fix in the next release. And for this moment, just grab the code from the Github repo and it should fix this issue.

I only changed the USB PID. I didn't notice there was a bug fix in DAP.[ch]. I've just pulled the version from master and will re-build and retry pyOCD.

nerdralph commented 3 years ago

Copying the CMSIS_DAP example files from master did the trick.

@sabas1080 I guess the DAP_SWD_TransferBlock didn't handle the situation well. Will do more investigation.

DeqingSun commented 3 years ago

@sabas1080 seems to be an DAP_PACKET_COUNT thing. The default is 4 while this implementation didn't do a queue. And pyOcd is trying to run 4 commands before get 4 responses. Changing DAP_PACKET_COUNT to 1 seems help. Will test again with different environment.

Now all softwares have been tested. The update is in the main branch now.

@DeqingSun nice!, Working for me :D
