Flash Loader Ip Not Loaded On Device 1 -

Few things are more frustrating in embedded development than a successful connection to your microcontroller, only to be met with the cryptic error:

The "Flash Loader IP Not Loaded on Device 1" error sounds complex, but it usually means the CPU is asleep or stuck. By using or switching to the System Memory Bootloader , you can almost always recover the device. Never throw away an STM32 that shows this error – it is almost certainly recoverable.
