На плате обрезал две земли идущие к ножкам VCAP 1 и 2 и подключил к ним конденсаторы.
Сгенерировал новый system_stm32f4xx.c под кварц 8МГц.
Для начала захотел подрыгать ногами. Подредактировал проект IO_Toggle из STM32F4-Discovery_FW_V1.1.0 , но на ножках ничего не меняется, хотя в дебаге в Keil'e состояние портов меняется.
Пробовал переделывать проекты из STM32F4xx_DSP_StdPeriph_Lib_V1.0.0, но на ножках все так же глухо, хотя в дебаге все меняется.
Каким то образом один или пару раз логическим анализатором увидел генерацию на ногах, голова к тому моменту была уже квадратная, поэтому не запомнил ничего .
Может кто сжалится и подкинет проверенный проект для запуска этого МК (дрыгание ногами или работа с USART). Есть подозрение что сам МК дохлый.
Дрыгать пытаюсь PA7, PA8, PA9, PA10
Flash Loader Demonstrator коннектится к МК через USART на ножках PA9 PA10
