Re: [ECOS] ISR problem

[ram kumar <ram_ecos at yahoo dot co dot in>]

Thanks Bart Veer.

My DSR is working well for COM2, but in case of COM1
its not working correctly. On initialization of COM1 I
am getting a message. 

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
hal_arch_default_isr: 33 (data:0)
hal_arch_default_isr: 43 (data:0)
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

And then every thing stops.But my ISR is using vector
35. Please give suggestions. 

Thanks & regards,
Ram Kumar
