qemu emulate stm32p103 got "Reached end of schedule()" #123

Closed louisom closed 7 years ago

louisom commented 7 years ago

Using QEMU-stm32 to run stm32p103, got reached end of schedule()

using default config file. with arm-none-eabi-gcc version 6.2.0 (I've check this version toolchain can work on stm32f429)
