ItsyBitsy M4 COM port disappearing after upload

ewoolsey · July 1, 2022, 6:54am

Having trouble with platformio and my itsybitsy M4. After upload, it disappears on both my mac and PC. The only way to get it to show up again is to double tap the reset. I’m using TinyUSB. As well the Serial connection is obviously unavailable during this time as well. I’ve seen others with this problem but no solution. I should add that this happens no matter which sketch I am using. Here is some info:

Thanks for the help!

Add

lib_archive = no

to the platformio.ini and reupload.

interesting, what does this do?

TinyUSB has an eternally unmerged PR Hint platform io to not statically link by JoonasMelin · Pull Request #116 · adafruit/Adafruit_TinyUSB_Arduino · GitHub that the library needs due to linker internals (correct linking of interrupt handlers needed for USB) but was never merged.

Hm that’s not good.

Can you either turn of TinyUSB (remove build_flags) or create a new project with no libraries but just

[env:adafruit_itsybitsy_m4]
platform = atmelsam
board = adafruit_itsybitsy_m4
framework = arduino
build_flags =
   -DUSE_TINYUSB
lib_archive = no

and a

#include <Arduino.h>
#include <Adafruit_TinyUSB.h>
void setup() {
  Serial.begin(115200);
}
void loop() {
  Serial.println("test"); 
  delay(1000);
}

to test whether TinyUSB works in principle?

ewoolsey · July 1, 2022, 4:29pm

Really appreciate your help! I’ll try that right now and get back to you.

ewoolsey · July 1, 2022, 4:36pm

OH MY GOD THAT WORKED. This problem has lost me like 6 hours of frustration. You are my saviour. Now, any ideas how to fix those compilation errors with the rest of my code?

maxgerhardt · July 1, 2022, 6:34pm

Thank Hint platform io to not statically link by JoonasMelin · Pull Request #116 · adafruit/Adafruit_TinyUSB_Arduino · GitHub for never getting merged and it not getting looked at on the PlatformIO side

This seems really weird. Why is there Adafruit_FlashTransport_SPI.cpp and Adafruit_FlashTransport_SPI 2.cpp? That doesn’t appear in Adafruit_SPIFlash/src at master · adafruit/Adafruit_SPIFlash · GitHub. It almost looks to me like someone just duplicated the file.

Can you remove the .pio folder of the project to get a clean redownload of the libraries when you build again?

ewoolsey · July 1, 2022, 6:36pm

Sure! will try.

Also just this header file is enough to cause those errors FYI:

#define _FLASHSTORAGE_H
#include <Arduino.h>
#include <SPI.h>
#include "SdFat.h"
#include "Adafruit_SPIFlash.h"

//general file access functions

//read 32-bit (4 byte) unsigned int from file
uint32_t read32(File &f);
//read line (until \n ) from file and save it to l
//skips all whitespace (including CR and tab)
int readLine(File &f, char  l[]);



void msc_init();   //initialize mass storage object

That’s uh, interesting.

With what code configuration was it broken before?

Uploading a minimal TinyUSB serial sketch repeadedly as shown above also results in this error?

When not using TinyUSB everything is fine?

ewoolsey · July 5, 2022, 1:34am

Hey there, sorry for the slow reply, was away for the long weekend.

Uploading a minimal TinyUSB serial sketch repeadedly as shown above also results in this error?

yes it does

When not using TinyUSB everything is fine?

Yep, If I don’t use tinyusb I have no problems.
Any ideas?

ewoolsey · July 5, 2022, 2:11am

As an additional follow up. Everything is 100% working on my windows machine when using the changes you suggested. It is just my M1 Max Macbook Pro that gets the SAM-BA error. I have done lots of googling and cannot find a solution I would really like to develop on my Macbook so if you have any ideas that would be amazing. Maybe a driver issue?

maxgerhardt · July 5, 2022, 9:03am

Sounds like Short delay to ensure port is flushed in OS X (and prevent download h… by dledge · Pull Request #121 · shumatech/BOSSA · GitHub or better Fix MacOS write error caused by unflushed buffer by kaysievers · Pull Request #150 · shumatech/BOSSA · GitHub? Are you able to recompile BOSSAC from source from the latter fork?

If you have patched binaries, use them to replace ~/.platformio/packages/tool-bossac@<version> (you get the version number in the “PACKAGE” overview at the start of compilation).

maxgerhardt · July 5, 2022, 11:24am

Hm in fact, Releases · adafruit/ArduinoCore-samd · GitHub fixed that implicitly by updating the bossac version that incorprates that fix by… downgrading to 1.8.

You should be able to download the precompiled binary at http://downloads.arduino.cc/tools/bossac-1.8-48-gb176eee-i386-apple-darwin16.1.0.tar.gz. Place the bossac executable from there into the right tool-bossac folder as detailed above and retry.

ewoolsey · July 5, 2022, 3:06pm

Man you really know your stuff… Thanks so much. Heading out visiting family for the week so won’t be able to test until next weekend. Will be sure to reply then!

ewoolsey · July 11, 2022, 12:27am

Using the binary you linked Does not improve the situation it seems. It is now disappearing from the com port again after upload on my Mac.

maxgerhardt · July 11, 2022, 6:42am

And this is with your full sketch or ItsyBitsy M4 COM port disappearing after upload - #5 by maxgerhardt?

ewoolsey · July 11, 2022, 6:28pm

Both unfortunately. With the old binary it doesn’t disappear from the com port, but reupload fails with sam-ba error.

maxgerhardt · July 11, 2022, 6:31pm

Please open an issue at Issues · platformio/platform-atmelsam · GitHub so that the devs can work on this.
