Unable to upload Blink to MAX32620FTHR board

[technoblogy]

I've just received a MAX32620FTHR board and I'm trying to develop an application for it, but I don't even seem to be able to successfully upload Blink to it.

I'm using Arduino IDE 1.8.5 on a Mac (High Sierra) and am following the instructions here:

https://github.com/MaximIntegratedMicros/arduino-max326xx/wiki/MAX32620FTHR#programming-the-max32620fthr

I've tried with the Native USB Port, and the Arduino IDE just hangs up at the "Uploading..." stage. Note that there's no USB port option available on the Tools->Port menu, which is suspicious.

I've also tried with the Programming Port, connecting the MAXDAP adapter to the MAX32620FTHR board, and both boards to the Mac via USB cables. Again, the Arduino IDE just hangs up at the "Uploading..." stage.

I hope someone can help me get started!

@technoblogy We're looking into this issue.
If there's no Port available, can you make sure the board is plugged in properly and gets enumerated?

Do you see a mass storage drive named 'BOOTLOADER' or 'DAPLINK'? If yes, can you try to do the following:

1. From IDE, Sketch->Export Compiled Binary. You'll see a new .bin file in your sketch folder.
2. Copy and paste the .bin file to the mass storage drive.

Thank you for your reply.

It's definitely plugged in properly. What do you mean by "enumerated"?

Do you see a mass storage drive named 'BOOTLOADER' or 'DAPLINK'?

Yes, BOOTLOADER.

From IDE, Sketch->Export Compiled Binary. Copy and paste the .bin file to the mass storage drive.

That works fine.

I uploaded a Blink example on MAX32620FTHR on Mac OS Mojave running Arduino 1.8.5. Everything worked as expected.
If you were able to successfully copy-paste the exported .bin file then you can be sure that the board and the Arduino support package works fine.

Would you mind trying it on a different computer?

Note that there's no USB port option available on the Tools->Port menu, which is suspicious.

This is a Serial (COM) port, not a USB mass storage port. When you connect using the Native USB port and see a BOOTLOADER drive, there won't be any Port available. If you connect using a MAXDAP adapter and see a DAPLINK drive, you should see a Port available.

Checked again. Here's what happens:

Plug in the board. The Blink sketch uploaded via the exported .bin file runs, the LED flashes slowly, and I get /dev/cu.usbmodem1411 on the Port menu.

Hold down the Boot button, press and release the Reset button, and release Boot. The LED is now on steadily. /dev/cu.usbmodem1411 has disappeared from the Port menu.

Select Upload. I get the error:

java.lang.NullPointerException

and the Arduino IDE hangs on Uploading...

If I can get hold of another Mac I'll try it on that.

I've now successfully run my Lisp interpreter for microcontrollers, uLisp, on the MAX32620FTHR:

uLisp - Lisp for microcontrollers

I uploaded it via the exported .bin file, and communication via the Arduino IDE's Serial Monitor works nicely.

I have a few questions about using the Arduino IDE with the MAX32620FTHR. Should I ask them here, or would it be better to email them directly to someone?

I've contacted you via your uLisp email ID.

I have the same problem on my Mac: If I try to upload an Arduino sketch (1.8.5) the IDE hangs during upload. I did it using DAPLink and board 'MAX32620FTHR (Programming Port)'. After a while I got the message 'Upload finished' but the max32620fthr wasn't programmed. I even tried using 'Upload using Programmer' without success.

I did the same with Arduino IDE 1.8.5 on a PC running Windows 7 and it worked.

Would you please look after this issue because I usually use a Mac and it isn't possible to program max32620fthr using Arduino IDE on it.

...message during 'hanging' of the IDE: Searching for Maxim board in /Volumes

Uploading the sketch using the PC overwrites the bootloader. Re-burning bootloader can be done with PC but not with Mac. Bootloader Version: 0242

@SchneHa I'm not sure if I understand your problem exactly. I don't see any issue with the message "Searching for Maxim board in /Volumes" on Mac for uploading a sketch.
The original post mentions about IDE being stuck at "Uploading..." stage. Do you have a similar situation?

The MAX32620FTHR can be programmed in 2 ways, have you looked into this?

Re-burning bootloader can be done with PC but not with Mac.

I'll double check this.

@khariya yes, it’s exactly the same problem. I see the message and the uploads stucks. After a while the upload seems to be finished but the message is still there and the upload didn’t succeed.

Programming and burning bootloader using a PC works well but programming overwrites the bootloader. After burning bootloader again I can see the volume ‚Bootloader‘ and drag the .bin file to it but thereafter bootloader is overwritten again.

I know the document the link refers to. But it isn’t how it is described. I can’t set the board into boot mode by holding down Boot button and releasing Reset button. And dragging a file to ‚Bootloader‘ overwrites the bootloader on the board as I wrote.

@SchneHa I just tried the "Burn Bootloader" feature in the following environment:
Mac OS X version 10.11.16
Arduino IDE 1.8.5
Maxim's package 1.1.4

It works fine with the instructions mentioned here.

Can you provide the steps to reproduce the issue your facing? Please include the connections of the board(s).

If you get the "Upload Finished" message on IDE at some point, then I don't see where it gets stuck.
How long does it display the message "Uploading..."? If it's only a couple of seconds then that's normal.
From your explanation, it looks like your upload succeeds but fails to run the program in an expected manner. Is that true?

Mac OS X version 10.12.6

Maxim's package 1.1.4

DAPLink adapter isn't flashing, uploading stucks for about 10 minutes, after that I see the following:
