Hello,
I am using a board that we have designed in house that uses the NXP LPC3250 with 2 SST39LF800A flash chips connected to chip select 0 (CS0) and 2 SST39LF800A flash chips connected to CS1. Each chip is connected in 16 bit mode, 2 to the low 16 bits and 2 to the high 16 bits of the LPC3250 to provide a 32 bit memory interface. We have purchased the J-Flash license and are trying to implement flashing support to this board. I see the SST39LF800A as one of the Flash chip options but I can't seem to figure out how the settings should be configured to make this work. Two of the flash chips would have to be programmed simultaneously to program the full 32 bit width. Does J-Flash support this configuration? Is there any documentation available to aid me in this setup?
Thanks,
