[ts-7000] DIO2 for basic I/O

["lazo93600" <>]

Dear,
 
My configuration :
----------------------------------------------
TS7260 with kernel 2.4.26,
no sdcard,
no use fo TTL com configuration
-------------------------------------------------
 
I manage easily to make DIO1 and LCD port worked, but the DIO2 might be some 
different configuration.
I didn't manage to use DIO2 as basic DIO cause the configuration register isn't 
applied.
This is the code that i used, i don't think so that's a coding problem, but I 
think that's a configuration problem.
 
Hope you could help me.
 
Thanks
