then, I know this is not a “product” in the meaning that it must be perfect. anyway i am having some boring issues uploading sketches on my maple mini
usually to upload a new one i need to press the reset and then the user button 32, i read somewhere that in this way it goes in another bootloader mode (led blinking quite fast), correct?
another problem is that if i am not wrong everytime that i open the serial port the board should reset, it doesn’t happen

maple mini (aliexpress clone)

Resetting USB to switch back to runtime mode
i have to clarify that i am a hobbyist on my first tests with linux (installed yesterday) even if i try to study as much as i can sometimes i am not able to solve this kind of problems on my own… i think i wrote all i know, any help would be very appreciated!
i usually have more than one serial port connected, the port will need selecting correctly only if its not the last serial interface connected.
i plug in, in sequence
open logic sniffer on /dev/ttyACM0
usb-serial1 on /dev/ttyUSB0, connect uart1 pa9/pa10, & gnd almost always
usb-serial2 on /dev/ttyUSB1, connect is a maybe on uart2
then i connect the board, which is usually /dev/ttyACM1or /dev/ttyUSB2, if i connect it before the usb-serials then it will need to be selected again between ttyUSB0 and ttyUSB2/3 as ttyUSB1 ( and ttyUSB2? ) is / are in use
stlink is usual but it’s not mapped to /dev/tty*
this mainly because i also use bare metal with unicore-mx library. i always upload via stlink on either one.
btw istr that /dev/ttyACMn increments on a reset?? or is it power sequence, limit is ttyACM31

for the maple mini (clones) the led is normally on board and i’d think the arduino ‘hello world’ blinky sketch pretty much works out-of-the-box
https://www.arduino.cc/en/tutorial/blink
if things didn’t work, lookup the board layouts and schematics to see where those pins are routed
good sources of info are in the wiki
http://wiki.stm32duino.com/index.php?ti … 103_boards
http://wiki.stm32duino.com/index.php?title=Maple_Mini
http://wiki.stm32duino.com/index.php?title=Blue_Pill
To be honest I wouldn t say it is a plug and play
the port will need selecting correctly only if its not the last serial interface connected.
interesting i didn t know it, now i understood the reason why it didn t worked!
I think that your approach of using ACM0 for programming and the pa9/10 for serial is the best one. To be honest i didn t understood all your message
Somewhere i read that the maple mini changes the indexing of the serial ports, could someone confirm it?
Ag123 the board is a maple mini as in the link you posted
buffer is only 24k, so a short time at rate.
also anything connecting to the target, it’s signals and ground except for things you power from it.
if the boards usb is the last thing connected, it’ll stay last
rest will arrive with age

perpetual boot loader mode keeps the maple mini in the dfu mode, which is needed to install the sketch
i’ve documented my initial novice struggles in the 2nd link above
I would like to ask you some questions since looks like you had my identical problems/question using this board. I would like to say that i already use it and it works but i love to understand “things”
The dfu mode = perpetual boot loader mode = boot0 1 & boot1 0 (sistem memory)?
What is by the way the ram memory? I remember that the first time i plugged the maple in my pc the led started blinking superfast, it was that mode? Or it was the original bootloader?
Why i could choose the cpu speed of 72 and 48? There is a particular reason? Not considering current saving projects

if i didn’t understand wrong with the -a command i can choose where i want to put my sketch
so i can’t choose -a 0 since it is the start of the ram memory where there is the bootloader
-a 1/2 i will upload the .bin using the board bootloader
there is something weird that i don’t understand, why i could choose to upload the sketch in position 0x8005000 or 0x8002000? usually someone want to upload at the end of the bootloader so i should set -a 2 (0x8002000) indeed when i tried with -a 1 it didn’t worked!
Anyway just for your fun i would tell you that I thought that i was able to upload a sketch using any usb-serial converter wrapped on the serial1 
i will buy a st-link clone since they are cheap and if i will ever mess with the bootloader i will be able to upload it again
is your boot loader the stock bootloader or the stm32duino bootloader?
to tell that you need to run dfu-util -l on the command line
search for that, goto the directory where you installed arduino ide, and run find . -name dfu-util
find . -name dfu-util

./hardware/Arduino_STM32/tools/linux/dfu-util/dfu-utilI already played a little bit with dfu-util, in the last post i wrote you that i wasn’t able to upload a .bin using “-a 1” and i was wondering why this address is still there since using the stm32duino booatloader i should be able to upload at 0x8002000 and not 0x8005000
It is not something important it is just a stupid curiosity
i tend to use only a st-link egg for uploads on the jtag 20w
while trying the various F407 versions (HAL/libmaple) i noticed that the restart doesn’t always happen.
then a reset always does, but not sure if an immediate recompile and download always does?
btw

I am quite sure that even for the blackpill it would work, and in this way i should have a more powerful programmer than the st link (even if i don t have any idea how to do in-chip debugging, yet)
i think the BMP runs a gdb server on the soc itself, which means that probably even things like openocd isn’t needed, you can most likely connect to it directly from gdb
in a way the ‘status quo debug/flash interfaces’ are things like st-link (which is st propriety) and openocd ft2232 jtag/swd. but i’d think we’d not need to keep sticking with the ‘status quo’, BMP may be a good alternative in that sense. best of all it’d seem it can be flashed on any blue pill or maple mini
(but a small catch is that you may need a uart dongle or st-link firsthand to flash that at 0x8000000)
another way is to use a spare blue pill/maple mini and flash a ‘sketch’ that basically turns usb-serial to usb-uart
just 2 cents
I thought i was able to flash the bmp software after the bootloader
in your ld scripts, you would need to update the origin for flash so that it would offset away from 0x8000000 leaving room for the bootloader
e.g.
MEMORY
{
RAM (xrw) : ORIGIN = 0x20000000, LENGTH = 20K
FLASH (rx) : ORIGIN = 0x08005000, LENGTH = 108K
...
