Thanks for all the messages !

So I made a bit progress ! The Koduino library was surprisingly easy to set
up and use.

Edoglando, funny you should ask ! Out of the 10 boards I have, 4 seem
not to like the programming and do not execute my test sketch. The other
6 appear to work.

Now, I have 6 blinking boards and 4 "dead" ones. The dead ones are quite
interesting, and I wonder if it is a programming "bug" or "feature". I can
program the Flash, and read back, even after power cycling, BUT, it does
not execute my simple blinking sketch. I have also been trying to force the
use of HSI, instead of HSE to avoid external crystal issues. Not sure if that
has propagated now or not, or even if it will become effective when using
dfu, or I must use st-link.

I ideas guys ? Sound like a strange issue, and 4 boards having the same
issue, is also strange ...

BTW, destroyed a second st-link adapter last night. What's wrong with these
things, ? Looks like the LDO is dead, if powered by external battery it seems
to work :/

Many Thanks,
rudi
Perhaps a bad solder somewhere and the MCU pins for boot0 and boot1 are left floating?

there doesn't seem to be a 'verse' for the generic f407 in boards.txt

this board is from https://www.aliexpress.com/item/STM32F4 ... 0.0.z0LbZh

very kindly they give https://www.aliexpress.com/item/STM32F4 ... 0.0.z0LbZh

if you toddle off there and get the 39M zip, unzipping gives a missing central something error :(
i did a rename to lose the spaces and shorten it
then

Code: Select all

zip -FF STM32F407VET6VGT6.zip  -o 0123456.zip
i use midnight commander and also do a rename to lose weird :) font characters when extracting

Code: Select all

total 39672
