I'm using lpc1768 controller keil RTX rtos and uart receive function by an interrupt. I was set a NVIC priority using NVIC_SetPriority(UART1_IRQn,1) while thread processing it don't goes to IRQHandler if any uart rx interrupt was occur. After finish the thread process then goes to IRQ Handler. I don't know how to set a high interrupt priority using RTOS. Please help me to solve this issue.
Thanks & Regards, Prasanth.
