"Simple Socket Server" demo code stop after display "simple socket server starting up

You must write 1 to the edge capture bit in order to clear irq.

Then the correct command in irq handler should be:

IOWR_ALTERA_AVALON_PIO_EDGE_CAP(LOAD_BASE, 1);

Probably the problem is simply here: irq is not cleared, thus keeps on retriggering and your code gets stuck.

Hello Cris72,

I have do the change as you suggest, but it stiil stuck at same place....no change ...!!

Sorry, I suggested IOWR_ALTERA_AVALON_PIO_EDGE_CAP(LOAD_BASE, 1)

but actually you should use IOWR_ALTERA_AVALON_PIO_EDGE_CAP(LOAD_BASE, 0xf)

since I see you are using all 4 PIO inputs and the previous one would reset only irq for first button.

This must be changed both in irq handler and before alt_ic_isr_register calls.

Let me know if this way it works

Hello Cris72,

I have put IOWR_ALTERA_AVALON_PIO_EDGE_CAP(LOAD_BASE, 0xf) , but still it stuck at same point......!!!

but when i increase the data cache from 8 kb to 32 kb it start working and come up to my code area.

still it is not taking interrupt.

please look at the print screen of my project.

regards
