Code uploaded through platformio doesnt work, STM32F070

I have a project where in the first version PCB i used STM32F103C8T6 and the uploaded code through platformio worked normally, then in the next version i am using STM32F070CBT6, test code uploaded through Arduino IDE works no problem, then i tried uploading through platformio and nothing works, not even a simple blink. For arduino IDE im using STM32duino, but for platformio i am using malyanm300_f070cb, perhaps the json configuration file has a problem, so i tried changing some pin definitons but still nothing works.

Would really appreciate some help on how to fix this problem.

Best regards
