   Hello,
   I've got a Maple for playing with ARM processors, but i can't seem to be able to program it :(
   I tried all that's written on the wiki (page Troubleshooting) but the perpetual mode doesn't work and i can't flash a new bootloader because i don't have a serial port on my pc.

   Here's what dmesg says about the Maple:

   [ 9872.820218] usb 6-1: new full-speed USB device number 8 using ohci-pci
   [ 9872.989201] usb 6-1: New USB device found, idVendor=1eaf, idProduct=0003

   [ 9908.332633] cdc_acm 6-1:1.0: failed to set dtr/rts

   The maple gui tries to reset the Maple, but after some seconds it fails:

   Here's lsusb:

   What can i do?

   @edocod - is this a real Maple Mini, or an "eBay knock-off"?

   Perpetual bootloader does take a bit of practice, so please try to get there.

   It was from Aliexpress: http://www.aliexpress.com/item/leaflabs-Leaf-maple-mini-ARM-STM32-compatibility/32229442295.html

   Could this be the problem?

   I can successfully flash it from dfu-utils, so it's working. The maple ide, however, doesn't work:

   And now i have a continuously rebooting Maple Mini! Are there any logs for the IDE so i can check what's wrong?

   I think you have now downloaded a copy of the bootloader into the user application Flash, so that is not going to work :(

   To change the bootloader you would need to use the serial ROM bootloader or a JTAG/SWD connection. You can get USB-TTL serial adapters for a few $, so that is the cheapest route.

   The "Baite" branded Maple Mini clones seem to be quite reliable, and a lot cheaper.

   My one is a Baite one :9
   However, I can compile and upload code using the gcc toolchain, but it just refuses to run! Even the blinky sample doesn't work.

   edoardo@localhost:~/Scrivania/maple/libmaple$ make BOARD=maple_mini install
   Install target: flash
   ./support/scripts/reset.py && sleep 1                  && dfu-util -a1 -d 1EAF:0003 -D build/maple_mini.bin -R
   Could not find Maple serial port; defaulting to /dev/maple.
   Using /dev/maple as Maple serial port
   Failed to open serial port /dev/maple for reset
   
   (i press the reset button here)

   Oh! Here's what happened: I did make install without adding the variable BOARD=maple_mini, so the library was already compiled for another board. With rm -rv libmaple/build/* i deleted all the build files and it started to work :D
