Hi, I was wondering if I could use the Flash Loader Demonstrator to upload and download to the flash memory of the STM32f407. I checked on the website for SW demos under the STM32f407 and didn't find any software that I could use to program this chip using UART port.

Doesn't this version support the STM32F4 series? Pretty sure it does.
I added a direct link because the site is such a total cluster. I pulled it from the STM32F205 design resource page. I think people have had more luck with USART3 on the F2 and F4 parts, but there are very specific input pin requirements.2012-04-09 03:57 PM
Hi, Clive1
I downloaded the Flash Loader from the link provided and it works perfectly, I manage to load the flash memory using USART1. Now I would like to program my STM32 by USB. I downloaded DFUse demo but I don't get it to recognize my device. and I was wondering was it's the procedure to start the bootload sequence for DFU. For the Flash Loader to work I had to send a high to the BOOT0 line and this would start the boot sequence I am wondering if there is something similar in order to use the USB OTG capability. Thank for your help.2012-04-09 04:34 PM
BOOT0 being high is required for it to run the System ROM containing the loader. This will be required for serial or USB programming.
I don't use the USB connectivity, you'll probably need to review the documentation on the subject.2012-04-09 05:09 PM
Ok, I already have my STM32 in boot mode, however the device is not showing on DFUse, when I enter in boot mode my windows says that I need some drivers, do you know which drivers it is talking about.
Thank you very much for your help.2015-05-19 03:59 AM
Hi clive1,
In the Version v2.7.0 from 15-September-2014 the STM32F4 is missing.The Flashloader contains only f1=STM32F1f2=STR75xf3=STM8f4=STR91xFAf5=STM32L1f6=STM32F2f7=STM32F0STM32F4 with ADDR_FLASH_SIZE=1FFF0000;START_FLASH_ADDR=08000000;is missing.Best regards Wolfgang
