Because EASYMX PRO v7 STM32F407VGT6 is available from DigiKey , my plan is to start using it instead of Diymore STM32F4 which works fine under same below mentioned conditions.
A brand new EASYMX PRO v7 STM32F407VGT6 fails to connect to Cube IDE and CubeProgrammer while Diymore STM32F407VGT6 works fine.
Schematic wise these two boards are very similar. In my opinion, they should work with identical .ioc configuration . Please. correct me if I am wrong.
It seems like it needs some extra hardware setup or configuration. Please advice.
Last time I had similar issue the reason was a counterfeit IC. Hopefully this is not the case with Miroe.
1.) Cube IDE settings
2.) .ioc graphic setup : PA14 - SWCLK , PA13 - SWDO,
3.) Debuggers: a) st-link v2 or b) st-link USB Dongle
