Error: Please specify `upload_port` for environment or use global `--upload-port` option

basprins · August 4, 2021, 7:07pm

Hi,

I am using platformio to develop for an NXP imx rt 1020. Since I use freertos+lwip+pppos I choose to not make use of zephyr, but to copy all the necessary NXP files into my hand crafted “nxp library”. I had some help setting up my project from this forum. It works fine, until I pressed the “upload” button instead of pressing F5 (debug).

So, running the project in debug works like a charm. Still, when I press the upload button I get this error:

Building .pio\build\mimxrt1020_evk\firmware.bin
Configuring upload protocol…
AVAILABLE: blackmagic, jlink, mbed
CURRENT: upload_protocol = mbed
Looking for upload disk…
Error: Please specify upload_port for environment or use global --upload-port option.
For some development platforms it can be a USB flash drive (i.e. /media//)

It seems to default to mbed upload protocol. I use the “segger jlink” when I press F5.

So I thought, lets specify upload_protocol = jlink, but that gives me this error:

Building .pio\build\mimxrt1020_evk\firmware.bin
Configuring upload protocol…

The terminal process “C:\Users\baprins.platformio\penv\Scripts\platformio.exe ‘run’, ‘–target’, ‘upload’, ‘–environment’, ‘mimxrt1020_evk’” terminated with exit code: 1.

Any idea how to get this to work?

Many thx in advance

upload_protocol instead.

basprins · August 4, 2021, 8:20pm

Ah sorry for the typo, I meant to say that. It’s correct in my pasted platformio.ini though.

maxgerhardt · August 5, 2021, 8:27am

That’s not good. Can you do the project task Advanced → Verbose Upload and copy-paste the log here?

The JLink.exe program has just died with error code 0xc0000005, which is a generic “access violation” error (source).

Either:

JLink.exe is completelly corrupted
there is a bug in JLink.exe causing it to crash

Can you remove the tool-jlink package folder so that PIO redownloads a fresh version? It should be C:\Users\<user>\.platformio\packages\tool-jlink. Then retry uploading.

If this is does not help, please manually open a terminal in the project directory and execute the two commands

C:\Users\<user>\.platformio\packages\tool-jlink\JLink.exe -device MIMXRT1021DAG5A -speed 4000 -if swd -autoconnect 1 -NoGui 1 -CommanderScript "D:\dev\bp\iobox\nxpport\.pio\build\mimxrt1020_evk\upload.jlink"
echo %ERRORLEVEL%

Do you obseve the same error message and code?

basprins · August 6, 2021, 7:41am

Deleted the tool-jlink folder. It gets downloaded again.

Running advanced/verbose upload gives me :

Processing script file…

J-Link connection not established yet but required for command.
Connecting to J-Link via USB…FAILED: Cannot connect to J-Link.

J-Link connection not established yet but required for command.
Connecting to J-Link via USB…FAILED: Failed to open DLL

Script processing completed.

Trying to upload in debug mode gives me somewhat more information:

It no longer can connect to the nxp board?!

I tried from Xpresso, that still works fine of course. But I guess it uses their proprietary NXP/Xpresso debugger?

My device manager shows the same as before:

I deleted that driver, but Windows keeps reinstalling this version of the DLL. I read :
GoJimmyPi: Fixing J-Link “No emulators connected via USB”: How to have J-Link work for both Segger Utilities and VisualGDB (although probably not concurrently)

But he has a JLink driver. I don’t. My NXP imx RT1020 should have a JLink probe, right? I noticed the SEGGER J-Link popup many times when uploading to my board in debug mode…

maxgerhardt · August 6, 2021, 7:44am

When you download and install the latest JLink version from SEGGER - The Embedded Experts - Downloads - J-Link / J-Trace (7.52b), can you connect to the JLink and the chip using the JFlashLite program that is installed with it?

Is that using JLink.exe and related or OpenOCD as debugger?

basprins · August 6, 2021, 8:02am

JFlash lite can see my board.

I don’t know what MCUXpresso uses.

maxgerhardt · August 6, 2021, 8:05am

I get to that screen to without having a JLink connected so that is actually a bad test. Can you try and connect to the chip within JFlash, not JFlashLite?

basprins · August 6, 2021, 8:12am

Ah, no, that doesn’t work.

basprins · August 6, 2021, 8:15am

PS: for what it’s worth. MCUXpresso uses this:

I guess there is no easy way to use that instead in platformio?

maxgerhardt · August 6, 2021, 8:21am

CMSIS-DAP can be supported, the latest platform code has a case for that

github.com

platformio/platform-nxpimxrt/blob/188113b50b7d0821792270bdb760386c9fb34c81/platform.py#L82-L85


      
          # J-Link / BlackMagic Probe
          for link in ("blackmagic", "cmsis-dap", "jlink"):
              if link not in upload_protocols or link in debug["tools"]:
                  continue

but the board manifest does not list cmsis-dap, so you would need to add it in that array

github.com

platformio/platform-nxpimxrt/blob/188113b50b7d0821792270bdb760386c9fb34c81/boards/mimxrt1020_evk.json#L21-L25


      
          "protocols": [
            "jlink",
            "blackmagic",
            "mbed"
          ]

locally (<user home>/.platformio/platforms/nxpimxrt/boards/mimxrt1020_evk.json), then upload_protocol = cmsis-dap should trigger starting OpenOCD with the interface/cmsis-dap.cfg file.

But is that really a CMSIS-DAP, did you not say there is a JLink connected?

basprins · August 6, 2021, 8:33am

How can I tell ? I have no idea how to see which onboard debug probe sits on an imx rt 1020 EVK board. All I can see is what’s in my screen. When I hit ‘start debug’ in MCUXpresso, it shows that it finds one probe: CMSIS-DAP. In the selection boxes below, I unchecked all except MCUXpresso IDE LinkServer. It finds the CMSIS-DAP probe.

On the other hand… in platformio, I’ve been using JLink. Where I could see the SEGGER J-Link popup appear when I hit ‘start debug’ (which shows erase/program status).

Can this board have both then?

I my attempts to get platformio working again, I also used Zadig to enforce certain DLLs, ultimately removing my COM port (which I think was used by SEGGER J Link). Weirdly enough, without this COM port, Xpresso IDE was still able to upload programs.

After reinstalling SEGGER JLink once more, I revived the COM port, but still the same result. JLink won’t upload anymore since it claims it can’t find a device and opens the emulator dialog.
