I don't know where it is stored (maybe a debug setting will reveal this) but the path is given as an argument to dfu-util so you can create a fake dfu-util to figure it out in the worst case. </p> http://forums.leaflabs.com/topic.php?id=9474#post-20919 Fri, 09 Nov 2012 07:18:50 +0000 cowana 20919@http://forums.leaflabs.com/ <p>Does the Maple IDE generate a .hex/binary file when code is built? If so, it would be pretty simple to manually flash this onto the chip via the bootloader. My board has a switch to select whether the serial bootloader is run or not on startup.</p> <p>Andy </p> http://forums.leaflabs.com/topic.php?id=9474#post-20914 Fri, 09 Nov 2012 06:44:53 +0000 tormod 20914@http://forums.leaflabs.com/ <p>The Maple IDE calls dfu-util to program the Maple, so I guess you could change some setting or script (batch file), to call a program like stm32flash instead. The Maple IDE does some signalling on the run-time virtual serial interface to get the Maple into bootloader mode, you'll have to adapt the run-time code accordingly or manually force your board into bootloader mode when you want to reprogram it.</p> <p><a href="http://leaflabs.com/docs/bootloader.html" rel="nofollow">http://leaflabs.com/docs/bootloader.html</a> </p> http://forums.leaflabs.com/topic.php?id=9474#post-20908 Fri, 09 Nov 2012 04:53:55 +0000 cowana 20908@http://forums.leaflabs.com/ <p>I've already got the boards I want to use, so I won't be able to to use the built in USB as it is not wired for it.</p> <p>My board allows for using the serial bootloader of the SMT32, standard JTAG programming or STM's SWD interface.

You may have to include that in your design to use Maple Bootloader. </p> http://forums.leaflabs.com/topic.php?id=9474#post-20888 Thu, 08 Nov 2012 17:16:25 +0000 tormod 20888@http://forums.leaflabs.com/ <p>The maple bootloader implements USB DFU, that is USB from one end to another. I am not sure I understand your questions, but yes, you can install the maple bootloader on your STM32 (with necessary modifications when it comes to pin-out for buttons and USB connect) and then use the built-in USB connected to your computer (and the dfu-util program).</p> <p>On the other hand, if you want to use the UART, you can not use the maple bootloader, but you can use the built-in (ROM) serial bootloader of the STM32 (and a corresponding program, e.g. stm32flash, talking to the virtual COM port from your FTDI converter). </p> http://forums.leaflabs.com/topic.php?id=9474#post-20875 Thu, 08 Nov 2012 05:15:04 +0000 cowana 20875@http://forums.leaflabs.com/ <p>I'm working on my first STM32 project, which uses an STM32F103RET6. I have designed a PCB with this and a few other I2C chips on. Rather than using the inbuilt USB, for simplicity I am using an FTDI USB-TTL converter connected to USART1.</p> <p>I'm very familiar with arduinos, and would like to use the Maple language/IDE for my projects. Is it possible to flash the STM32 with the maple bootloader (much as I often do to turn blank AVRs into arduinos)? Will I have an issue trying to use UART1 for the bootloader rather than the inbuilt USB?</p> <p>Many thanks for any thoughts or ideas!</p> <p>Andy </p>
