Uploading Sketch to Maple mini from Arduino 1.6.9 [SOLVED]

Is it a baite maple mini?
Which bootloader did you select in the IDE? Origonal or Maple Mini.
Did you select the com port in the IDE?
What device is showing in device manager?

Is it a baite maple mini?
Yes, its the baite maple mini clone. Bought it on aliexpress.com.

Which bootloader did you select in the IDE? Origonal or Maple Mini.
I selected bootloader 2.0 (20 kb RAM and 128 K flash). I selected the board as “maple mini”

Did you select the com port in the IDE?
Yes, the com port is selected as ttyACM0 (I’m using Ubuntu 14.04)

What device is showing in device manager?
I’m not using Windows. I’m using Ubuntu 14.04.

I’m able to upload the sketch only when the board is in perpetual boot loader mode.

OK so you upgraded the bootloader so it no longer has the original bootloader.

My Ubuntu box is headless so i may struggle to help you, but I will give it a try. I will see if I have a spare maple I can change the bootloader in.

As you are in linux to find out about the device unplug and replug your device. The run

dmesg | grep -i USB

try this; i have it in shell script called comms

ls -lt /dev |egrep 'stlink|ttyACM|ttyUSB'


I’ll post the result of ls -lt /dev |egrep 'stlink|ttyACM|ttyUSB'


that button pressing does get annoying, worse with fat fingers

permissions, if wrong cause the process to stop. that’s fine, but if incorrect mister blaster can kill anything.

Hey..
I did this:
ls -lt /dev |egrep 'stlink|ttyACM|ttyUSB'

Enter groups to see if you are a member of the dialout group.
$ groups
fred adm tty dialout cdrom sudo dip plugdev lpadmin sambashare

i’ve edited the relevant udev rules file /etc/udev/rules.d/25-ARDUINO.rules in my case to set stephen as OWNER and
set it as wide open with 777.
i suspect i got tee’d with it not working, so as it’s my laptop and i’m the sole user. … …
i know it’s not the proper way, but i’m an old mech eng with a spanner/hammer as reqd.

yes, I’m the member of the group ‘dialout’

ok.. thanks for the info! I’m sure that will come handy.
But I still haven’t gotten anywhere with my original question.
Do I have to put the board in perpetual boot loader mode before uploading a sketch?

i seem to have to, using stlink download, serial never seems to work.
even after it’s written to flash, i/o is problematic.

barest whiff of blue smoke, so bare i wasn’t even sure i’d seen it.
one sd module and the 16GB card inserted. 2 different makes of module, one pinning gnd, 3v3,5v; t’other 5v gnd

not good

ps. add a hub to the list

Hi Mr. Burnette,

I’ve a maple mini clone from baite. I bought it on aliexpress.com.
I burnt the new bootloader 2.0 named “maple_mini_boot20.bin” via FTDI 232 USB to Serial.
When I tried to upload sketch from Arduino IDE, it gave errors about not able to find any DFU device.
Then I put the maple in perpetual boot loader mode and hit “upload” again in the IDE. This time it uploaded the code and runs flawlessly.

My question is, do I have to put the maple mini in perpetual boot loader mode every time I want to upload the code? Can’t it be done with just hitting the upload button in IDE and not touching any buttons on maple mini? I’m using Arduino 1.6.9 on Ubuntu 14.04.

Specific to the Maple Mini (Baite) model: in my experience, 9 out of 10 times the COMx port will toggle the reset and put the Mini into DFU mode automatically. The other 10% it will not. My experience is with Win8.1 and Linux Mint 17.3 Other versions of OS’s may give completely different results, but I know of no one that has achieved 100% upload via the IDE without having to occasionally resort to the forced DFU mode.

Remember, for Windows, there is the requirement to install the serial drivers… see the WiKi.

There are a large number of posts on the forum about this issue which is why I did not respond to your PM, things need to be posted to be searchable.
Out site is fully Google indexed, so next time try a site specific Google query like:

9 out of 10 times the COMx port will toggle the reset and put the Mini into DFU mode automatically
That matches my experience. I always put a Serial.begin statement in the setup section, even if I don’t need it.

If uploading fails, I try again, pressing the reset and compile buttons at the same time. That usually lets it upload.

If your program uploads then crashes / locks up, then you may have to use the perpetual mode to recover.

I am using Mint 17.3, IDE 1.6.5, bootloader 2.0.

Thanks Mr. Bunette for the info.
Its not uploading even once without PBM on Ubuntu 14.04.
I guess I’ll have to use it this way only.

One possibility is that the modem manager thinks that the Maple serial port (which technically advertises itself as a stripped down modem) is a real modem and it’s trying to use it as such, preventing you from accessing it to reset it.

You can add a udev rule to prevent that:
ATTRS{idVendor}=="1eaf" ATTRS{idProduct}=="0004", ENV{ID_MM_DEVICE_IGNORE}="1"
