The setup consist of a STM32l152RE Nucleo board, with a LoRa transciever. The code base is the LoRaMac code from Semtech on Github - SensorNode version, as this is targeting sx1276. The IDE I use is Keil uVision v5.
The initial target is L151C8. I successfully changed the target to STM32L152R8 or RB and have the code properly run on the Nucleo board, fitted with STM32L152RE.
As soon as I move to higher feature MCU, such as RC, RD or RE, the timer interrupts are not raised anymore, preventing the code to properly work.
Is there any changes to be done when moving up in the range?
