Hi,
I am new to ARM and the KEIl tools so please forgive if Ive missed something basic here.
I have inherited a project using a ADUC7026 and am trying to achieve a tidy up of the project, the issue I am struggling with is:
I have several devices attached to GPIO which should not be turned "on" until the system is fully up and several checks have been passed. At power on (and during flash) the GPIO on these pins seem to be configured as inputs with the internal pullup enabled? Unfortunately the PCB is configured with logic level NFETS which turn on easily.
I've looked though the start up code and configuration wizard and cant find anything to help me there (can't say i'm an assembler guru though).
Is there anything I can do?
Thanks
Tim
