Hi!
can anyone send me some schematics, about how to route a system, where are:
-one SPI eeprom, connected to:
-a processor. (controller)
-and where i want to program the memory, with spi programmer. (not via the processor)
these things have to be in the same board, and i would like to program the memory in-system.
i am afraid of that the processor does not want to let this process.
what should i do? hold the processor in reset, while programming the memory (via an spi programmer, like ponyprog)? or use a dip switch, to isolate the memory from the processor? where to put the programmer's header?
please, some advice, and example schematic! thanx.
