Re: [ECOS] Need help - UART interrupt handler - ECOS

[Tathagata Das <tathagata@alumnux.com>]

Hello Sarvan,
   It may happen mainly for two reasons.
       1. Your interrupt controller is not working properly. However 
chance for this to happen is very less.
       2. You probably need to unmask the interrupt vector just after 
attaching ISR handler.
                    cyg_drv_interrupt_unmask(interrupt vector number for 
RX);

Regards,
Tathagata
