mark lazarewicz1 posted RE: Sysbios Hwi in BIOS forum.
I have modified the HWI_example to add a CAN RX ISR at vector 101 on the 28x335. I added this using the GUI
I send one packet only using PCAN tool The HW CAN registers show I have a mailbox RX IRQ pending which means my CAN Init is working but I never hit a breakpoint in the ISR
I removed all the example PWM HWI from the example after I was satisfied it worked and removed example call to init PWM. I also removed the Timer subsytem so I would only have my IRQ from CAN
i am using CCS5 and SYSBIOS 6.33 I created a new SYSBIOS project then followed instruction to add in HWI_example code once that worked I removed all ISR AND HWI using GUI except the CAN RX PIE vect 101
Forcing the PC to HWI_dispatcher and setting vectnum to 101 I step into ISR
i am running this example from Flash I am trying to understand what is missing in the connecting the Mailbox RX IRQ which I see when I transmit 1 CAN packet to HW and the interrupt service routine
Any suggestions ?
