UART Pressure Test

Test Methods​

  1. Enable the uart1 and uart2 nodes on the image (both sending and receiving), and short the TX and RX pins of uart1 with the RX and TX pins of uart2 on the hardware.
  2. Execute the test scripts: sh uart1test.sh &, sh uart2test.sh &.

Test Criteria​

  1. At high temperature (45°C), low temperature (-10°C), and normal temperature, the program should run normally without restart or hanging.
  2. There should be no abnormal prints in the LOG such as fail, error, or timeout.
  3. The program should run stably for 48 hours.
