I have some problem with programming my custom board board using Jflash. I use AT91RM9200_EK.jflash sample project and the flash base addr is set 0x10000000.When I choose "Use target RAM(faster)" and set "addr" to 0x200000, then when erase or programm the external NOR flash which is selected by NCS0 of AT91RM9200,it says "erase failed" or "programming failed". When I don't choose "Use target RAM(faster)" , everything is ok except the slow speed.
I compare AT91RM9200-EK with my board,the nor flash is different. I don't know whether this is the point.
Any help will be appreciated.
