Serial implementation uses different vector handlers for sync/async calls respectively. The issue can be reproduced with the following flow: 1. Register sync mode callback with Serial.attach(). 2. Sync call with Serial.putc()/getc(). 3. Change to async call with Serial.write()/read(). 4. Change back to sync call with Serial.putc()/getc(). Now, vector handller is still for async mode, not for sync mode. To fix it: 1. Introduce internal function serial_enable_interrupt() for both sync/async vector handler enable/disable. Original HAL function serial_irq_set() is reduced to call it for sync mode vector handler enable/disable. 2. Introduce internal function serial_rollback_interrupt() to roll back sync mode vector handler at end of async transfer. |

ARM mbed OS
mbed OS is an open-source embedded operating system designed specifically for the "things" in the Internet of Things (IoT). It includes all the features you need to develop a connected product based on an ARM Cortex-M microcontroller.
mbed OS accelerates the process of creating a connected product by providing a platform operating system that includes robust security foundations, standards based communication capabilities, built-in cloud management services, and drivers for sensors, I/O devices and connectivity. mbed OS is built as a modular, configurable software stack so that you can readily customize it to the device you're developing for, and reduce memory requirements by excluding unnecessary software components.
