anyone please tell me the connection of the Nandboot switch S2, one pin was connected to OM0 and the other to NANDboot, where we want to connect the NANDboot pin, this help me for my engineerng project
Micro2440 Boot switch S2
Do you micro2440-sdk, as there is nothing on the micro-2440 schematic that I can see. Had a look at how it is done in the mini2440 schematic and it suggests to me, that pulling OMO up to 3V3 through a 4.7K resistor will boot from NOR and pulling OMO down to ground through a 4.7K will boot from NAND. It looks like, on the micr2440-sdk, if you leave the connection OMO/NANDBOOT open-circuit it will boot into NOR and if you connect those two pins together it will boot into NAND. OMO must have a pull-up enabled. Are these instructions not in the user manual for the micro-2440?
thank u mr.davef ya I am askng abt the sdk oly. I nt seen these details in manual. I thnk the informatn gvn by u was useful to me. thank a lot
On the topic of the mini2440 Nand/Nor boot selection switch S2. Where does the NANDBOOT pin connect to exactly?
