FILES ------------------------------------------------------------------------- stm32lib/* - all the (possibly consolidated) stm32 lib and usb example code usb.c - USB-specific hardware setup. Interrupts, clocks, etc. handling USB when not "Attached". some low-level callbacks (low power mode, init, reset, resume, etc). usb_callbacks.c - aka endpoints: handling data transfer when "Configured". calls out to application specific callbacks (i.e. DFU). usb_descriptor.c - aka application descriptor; big static struct and callbacks for sending the descriptor. main.c - main loop and calling any hardware init stuff. timing hacks for EEPROM writes not to block usb interrupts. logic to handle 2 second timeout then jump to user code. hardware.c - init routines to setup clocks, interrupts, also destructor functions. does not include USB stuff. EEPROM read/write functions. dfu.c - mostly the giant FSM case switch, also some USB endpoint callbacks TODO -------------------------------------------------------------------------- * pack the structs * use sizeof() for usb application descriptor once structs are packed
Hello @mbolivar ,
I'm currently trying to write a serial bootloader and I discovered your serial-boot branch that includes the usb serial
I've changed the LED, BUTTON & DISC pin because I'm trying it on a Maple Mini, but it seems that my computer can't enumerate the USB device, I'm getting like "Device not responding to setup address" in my syslog
Do you have any idea what I'm missing?
I've been trying for several hours to get the maple bootloader to compile with GCC 4.9 which, for some reason, seems to be impossible. Even with "-O0" the resulting binary doesn't work. I did several tries to find the problem but failed so far.
Hi,
I've done some minor porting to get this bootloader working on the cm900 and on the opencm904 here:
https://github.com/Gregwar/maple-bootloader-robotis
I can't open a pull request to propose new branches, are you interested to merge them here?
It seems very strange that this repo contains a different branch for each target e.g. Maple, Maple mini etc
Wouldn't it be better to have one unified source with #defines in the Makefile for the Port and Pin numbers of DISC pin and the LED etc
So that a bootloader could be built by using Make maple-mini or Maple maple-rev3 etc
I'm trying to open bootloader project by Keil, is it work?

dfu-util v0.3 has some increased standards-compliance which make uploads that use it much slower. We'll need to include a quirks mode for it which sets bwPollTimeout properly, in order for users of the current bootloader still get fast uploads.

Incorrect indentation in stm32loader.py at line number 303
This screws up flash prgramming when built with -Os
Fixed in my git tree: nekromant@d7211dd
P.S. My code is quite reworked, see this post: http://forums.leaflabs.com/topic.php?id=1847
Hi
I can't see any config settings etc that would allow the bootloader to be built for the Maple mini.
Looking at the schematics the Maple and Maple mini dont use the same GPIO pin for the DISC or the Button (and probably not the LED either)
I can't see a specific Maplemini-bootloader repo either
Do I have to modify the GPIO pin value to allow it to build for the Maple mini ?

we cant just extend the bootloader live time for 7 seconds, thats ridiculous. is there something better? maybe have libmaple leave a message in memory so the bootloader lives longer when its reset from the ide rather than the user?
