Hi,
I tried to toggle the bit on 6 GPIO ports given on DM355 EVM board. I tried using mmap and the base address given was 0x01C67000. I tried to toggle GPIO64 pin. DIR45 offset is 60h. OUT_DATA45 is 64h. I have made DIR45 = 0x00; configuring all the ports in bank 4 and 5 to output ports. and then OUT_DATA45=0x01 making 0th bit high which is GPIO64. I also tried SET_DATA45 =0x01; I have kept an LED ont that port and tried but it was not working. Any body help me please.
thanks regds Gopi K |
