port.c from --Atmel-IAR-AtmelSAM9XEPosted by ddement on September 23, 2009 I'm trying to clone the port.c from the AtmelSAM9XE folder as the basis for a SAM9260 system, but built with an older (4.20) IAR compiler. I look at the prvSetupTimerInterrupt() code which uses the AIC_ConfigureIT() function to link the PIT interrupt to its handler. The handler is specified as vPortTickISR(). The comments in ISR code says it is called by a wrapper, but it sure doesn't look like that is how the AIC is set up. And I can't find a tick wrapper .s79 source file anywhere. Can anyone please clarify - is this really correct? Thank you. RE: port.c from --Atmel-IAR-AtmelSAM9XEPosted by MEdwards on September 23, 2009 IAR V5 using .s as the file extension, look for a file with .s rather that .s79. RE: port.c from --Atmel-IAR-AtmelSAM9XEPosted by ddement on September 23, 2009 Thank you - I did find the vectors and front end code which calls the C handler between the context save and restore. It makes sense with that code. I appreciate your help.
