Does not respont during flashing

[itsygithub]

Hi,

up till now I tried everything to flash my Pro Micro but during flashing the device does not respond anymore. To make them available again I flashed bootloader of Micro and Leonardo. After that it is also possible to just upload an simple sketch.

But flashing with microUPDI ist not possible. Here ist my output:

After several restarts of laptop with still connected device it is recognized as Bus 001 Device 005: ID 03eb:2145 Atmel Corp. ATMEGA328P-XMINI (CDC ACM) now. Really strange ... Will test as soon as my pcb arrived.

[itsygithub]

Now I tried everything I could imagine, other bootloader to start with, other computer for flashing and so on but everytimes I had the same problem. When I start the script manually and flash via USBasp it works without problems. But it will be flashed with wrong IDs and with this "DFU bootloader also no port will be created.

So is there any way to flash with USBasp to get the same results like flashing automatically via Arduino Software?

[MCUdude]

Sorry for being so slow to respond. I've sold quite a few microUPDI programmers, and I've yet to see others struggling with the issue you're facing.

I have two scripts here you can use to directly load the files using Avrdude. If you're installed the microUPDI flash addon to Arduino IDE, you already have these files somewhere:

https://github.com/MCUdude/microUPDIcore/tree/master/avr/firmwares/CLI%20flash%20script

[itsygithub]

Thanks for your answer. Exactly this script I used for flashing the device and it worked. But as mentioned in the description the "usb device" will recognized as "Atmels DFU bootloader" and no port will be created in Arduino Software. Also the ID is wrong so that the software is not able to identify the programmer. Summarized this means that flashing via this script has not the same effect that flashing via the software. Maybe I have to do additional steps to get the same result. Also it is possible that I did something wrong but there is no issue shown during flashing with this script.

[MCUdude]

So you're able to flash the microcontroller with the script, but it still doesn't show up as an mEDBG programmer?

The difference between flashing using the script or through Arduino IDE is that the script removes the stick Pro Micro bootloader and replaces it with a DFU bootloader that original mEDBG based boards ship with.

The bootloader does not need to be present for the application to work.

[itsygithub]

yes, that is correct! The IDs after flashing with this script: 03eb:2ff4 Atmel Corp. atmega32u4 DFU bootloader But for programming the Arduino software is asking for: 03eb:2145

[itsygithub]

This is the original message with choosen programmer "Onboard ..." when I try to upload: "avrdude: jtag3_open_common(): Did not find any device matching VID 0x03eb and PID list: 0x2145"

[MCUdude]

Thanks for the details! I did the exact thing you did with the script, and I'm facing the same issue as you. It's stuck in the DFU bootloader for some reason. I'll see if I'm able to remove it from the hex file, as there aren't any need for it.

This is how I turned my microUPDI board into a working one:

• Open Arduino IDE and burn the Leonardo bootloader
• Then go back to the microUPDI firmware uploader and try to upload again
• Success! (hopefully)

[itsygithub]

Thanks a lot for confirming the issue :-)

The described workflow I tried more that 20 times with the same result. I will do it again to get the complete error messages to post it here - maybe you have an idea when you see it.

[MCUdude]

What happens if you try this flash this exact hex file with the script? You'll probably have to edit the script the get the file name right.

[mEDBG_UPDI_1.13_no_bootloader.hex.zip]

[MCUdude]

Sorry, the DFU bootloader wasn't removed from that file! Try this instead:

mEDBG_UPDI_1.13_no_bootloader.hex.zip

[itsygithub]

Even with this file the DFu bootloader was flashed. Before I flashed bootloader for Leonardo.

avrdude done. Thank you. `

[MCUdude]

Did you see my last post? I uploaded the wrong file by mistake. The one that are available now has the bootloader removed. Try this. You can also view it in a text editor to make sure the bootloader is completely gone. Look up Intel Hex on Wikipedia if you're struggling to read it.

[itsygithub]

Sorry I did not see the correction - I will try again - thanks a lot!

[itsygithub]

Now the flashing worked, the device has the correct naming, ID and will be shown in Arduino IDE as Port. Just the mismatch is at an other adress now:

avrdude: verifying ... avrdude: verification error, first mismatch at byte 0x1127 0x20 != 0x28 avrdude: verification error; content mismatch

Then I tried to upload a "blink" to my bord with 3216 (attno.de) and it worked :-)

Thank you so much for your help - I am very happy now :-)

[MCUdude]

Great to hear it's working! But since you're still getting a mismatch error I'm starting to believe your ATmega32u4 might have a worn or slightly corrupted flash memory. But if it works that's great!

I'll update the microUPDI core files to include the hex while without the DFU bootloader, so other users in the future won't have these issues.

[MCUdude]

FYI a new version of microUPDIcore (v1.0.2) is now available, and it uses the hex file without bootloader as the main hex file when you flash it though Arduino IDE.
