ilmenator Posted July 2, 2014 Report Share Posted July 2, 2014 I can't find a jumper on the STM32F4 core board for the bootloader hold mode - what is the easiest way to get my core board back to life after it crashes with a hard fault during init? Thanks, ilmenator Quote Link to comment Share on other sites More sharing options...
mono Posted July 2, 2014 Report Share Posted July 2, 2014 ...had the same problem before! for me the easiest way was to re-flash the mios-bootloader. i know, it sounds silly, but it does the job...:D mOnO Quote Link to comment Share on other sites More sharing options...
ilmenator Posted July 2, 2014 Author Report Share Posted July 2, 2014 Yes, that's what I am doing, too - I just thought there might be a smarter way than plugging and unplugging USB cables. E.g. pressing and holding the "User" button on the Discovery board while powering up the unit... :smile: Quote Link to comment Share on other sites More sharing options...
TK. Posted July 2, 2014 Report Share Posted July 2, 2014 There is actually a very smart way: read the newbie documentation... ;-) -> http://www.ucapps.de/mios32_bootstrap_newbies.html Quote: MBHP_CORE_STM32F4 and STM32F4DISCOVERY: press and hold the blue "User" button, trigger the black "Reset" button shortly. This will restart the core and enforce bootloader mode as long as the blue "User" button is pressed. Depending on the OS you are using at the host side (Windows, MacOS, Linux) it might be required to restart MIOS Studio in order to connect to the "safe" USB interface port. Best Regards, Thorsten.

ilmenator Posted July 2, 2014 Author Report Share Posted July 2, 2014 RTFM strikes again - I was pretty sure something like that was implemented, but I didn't see this in the docu... my bad! Quote Link to comment Share on other sites More sharing options...
