Halcogen forgets the #pragma enabling EMAC interrupts

Hello:

We have received your post. An expert will review it and provide the requested feedback.

Regards,

Note that this could be the reason why the example in the lwIP/Emac

HALCoGen_Ethernet_Driver_and_lwIP_Integration_Demonstration

cannot drive to a working code.

Hi Matteo

The pragma directives control the behavior of the compiler, for example how it allocates memory for variables and functions etc ..etc It should be documented as part of compiler documentation.

#pragma INTERRUPT(EMACCore0RxIsr, IRQ) tells that compiler that the function EMACCore0RxIsr is an ISR function of type IRQ. So that context switching, Stack allocations are taken care.

Unlike other modules EMAC ISR has to be provided by the User.

In LWIP demo ISR's are part of lwip_main.c

/*
** Interrupt Handler for Core 0 Receive interrupt
*/
#pragma INTERRUPT(EMACCore0RxIsr, IRQ)
void EMACCore0RxIsr(void)

/*
** Interrupt Handler for Core 0 Transmit interrupt
*/
#pragma INTERRUPT(EMACCore0TxIsr, IRQ)
void EMACCore0TxIsr(void)

Thank you. I know what a #pragma is. My question was: There is some document about #pragmas and other compiler switch for CCS?
