I followed the instructions on https://github.com/rogerclarkmelbourne/ … stallation
Then in “Perpetual bootloader” mode, i compiled MrBrunette’s Blink example and i get this error:
Build options changed, rebuilding all
Sketch uses 13,616 bytes (10%) of program storage space. Maximum is 128,000 bytes.
Global variables use 3,888 bytes of dynamic memory.

Re: Permissions
Try setting the permissions to 777 that worked for me
I was tailing the syslog with:
sudo tail -f /var/log/syslog
user@computer:~$ stm32flash /dev/ttyACM0

(Maybe we should move this thread to “maple mini” or “linux”?)
Noticed that whenever i put the device on PB mode, it disconnects, thus the IDE (or stm32flash) cannot find it.
Is this normal behaviour or the board is possibly bricked?
If the board blinks constantly from the start it sounds like it doesn’t have blink installed
Put the board into perpetual bootloader mode
press reset then hold down the other button for a few secs
The led should continue to blink
You should have a USB device called “Maple DFU” VID 1EAF/0003
Have you compiled and installed DFU Util, See the linux installation pages in the wiki
Once you have DFU Util installed you should be able to upload
Note you will probable need to set the permissions on the DFU device, I forget exactly what it is , something like /dev/bus/xxx etc
Do you have a Uno, its possible to reflash the bootloder with the new one using a Uno has a programmer if you really have problems
I’ve compiled dfu-utils 0.8 but not sure if it’s installed correctly. How to check it?
#!/bin/bash
set -e
if [ $# -lt 4 ]; then
echo "Usage: $0 $# <dummy_port> <altID> <usbID> <binfile>" >&2
exit 1
fi
dummy_port=$1; altID=$2; usbID=$3; binfile=$4
DFU_UTIL=/usr/bin/dfu-util
if [ ! -x ${DFU_UTIL} ]; then
echo "$0: error: cannot find ${DFU_UTIL}" >&2
exit 2
fi
~/dfu-util-0.8/src/ e.g.
cp ~/dfu-util-0.8/src/dfu-util /usr/bin
you may need to use
sudo
user@computter:~$ dfu-util -l
Found DFU: [1eaf:0003] ver=0201, devnum=12, cfg=1, intf=0, alt=1, name="DFU Program FLASH 0x08005000", serial="LLM 003"
Found DFU: [1eaf:0003] ver=0201, devnum=12, cfg=1, intf=0, alt=0, name="DFU Program RAM 0x20000C00", serial="LLM 003"
Note you will probable need to set the permissions on the DFU device, I forget exactly what it is , something like /dev/bus/xxx etc
Linux is not my area of expertise. Try PM’ing @ahull or @RickKimball they are both Linux experts, one of them may be able to help you

I can confirm, i have dfu-util correctly installed.
The problem is “kind of” solved now: Installed Maple IDE v0.0.12 
<command-line>:0:1: error: macro names must be identifiers
Error compiling.
The reason the Generic STM32F103C Series board doesn’t upload via DFU, is because generic boards don’t have that ability. Only boards with the additional USB reset hardware can use the Maple Bootloader which handles DFU upload
I will however check whether I get the same error when using the Maple Mini option
Thing is, i can upload a simple blink sketch via Maple IDE.
That board is a maple mini
You need to use the maple mini board type
I will need to check on my Linux machine if I can replicate the same issue
