[ts-7000] Re: TS-7390 - Sample program button.c not working for me

["happy_plattler" <>]

Hi Charlie,

I did the suggested change:

   int fd = open("/dev/mem", O_RDWR|O_SYNC);

but the result stays the same: not blinking.

I thought perhaps I should try a similar program so I tried the DIO_TS7800.zip 
package which is based on the same code but I get nothing here either except 
this output which is a bit cryptic:

DIO test app
Opening /dev/mem file
DIO: Mem file open successful, Page size is : 4096

Address assignment successful 0x2aac2000 0x2aac2004 0x2aac2008

main: init complete

LED SERVER_CON : 0
LED CHANNEL_1 : 0
LED CHANNEL_2 : 0
LED SERVER_CON : 0
LED CHANNEL_2 : 1
LED CHANNEL_1 : 0
LED SERVER_CON : 0
LED CHANNEL_2 : 0
LED CHANNEL_1 : 1
LED SERVER_CON : 1
...

Any other ideas perhaps.

Thanks,

Ole
