I would like to know if there is something wrong in my setup.
I have a custom board s3c2442BL based.
I ported some test points into a strip just to have an "expansion connector".
Those pins are GPA12..GPA16. On reset they are at 1.8V is it normal?
If I configure them as OUTPUT in GPACON register and write the corresponding
bit High its level remains 1.8V not 3.3V. Is it normal? It looks like it has
some PULLDOWN register enabled, but the GPIO A is the only port that *DOES NOT
HAVE* such register (from port B to port J they have PD regs...)
They are wired DIRECTLY from CPU pins to strip pins. No pullup, pulldown or
Something weird in the user manual?
Any help, clue?
