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);

Hello,
we are using ECOS for our development. In our environment(PNX 8330) Uart Rx
is configured in Interrupt
mode and the handlers are registered using ECOS exported API
(cyg_interrupt_create) and the handler
is attached in interrupt stack using (cyg_interrupt_attach).
cyg_interrupt_create() returns valid handler, so we can assume that the call
is success.
ISR handler is not being called, when we send a character from the
hyperterminal. But my uart status
register says Receive_therslod_int and receive_time_out both happened.
Could somebody Please, let me know why the ECOS is not calling ISR handler.
Should i need do any additional configuration in configuration tool to get
the handler.
Should i have to enable some macro to get the same.
Thanks in advance
