I tried to get the bootloader DFU works on NUCLEO-F303ZE, but it's didn't work.
For try to use it, I jump from my software to bootloader,
If I remap the memory to System Flash memory or not it change nothing.
If I go to bootloader with BOOT0 Pin the DFU didn't work also.
My HSE (MCO of STLink) seen to be OK.
The NUCLEO-F303ZE have not an external pull-up 1k5 Ohms, like is specified in
http://www.st.com/content/ccc/resource/technical/document/application_note/b9/9b/16/3a/12/1e/40/0c/CD00167594.pdf/files/CD00167594.pdf/jcr:content/translations/en.CD00167594.pdf
:
When I had my self an external pull-up Windows recognize a new USB device but is not identifiable and he said that my devices not working.
It's not easy to debug this in Assembly mode... It's seen to be in a loop 'while'.
So I don't know what to do for use DFU in with this microcontroller.
thank you for you response and what I need to respect for use it !
