Configure flash programmer + Check flash memory area in the memory map. + 0xFFC00000 - 0xFFFFFFFF + + Boot monitor program is at + 0xFFF00000 + + You can program on-board flash memory with VisionClick + flash programmer. Set the target flash device as: + + 29DL800B + + (?) The flash memory device in the board *is* 29LV800B, + but I cannot program it with '29LV800B' option. + (in VisionClick flash programming tools) + I don't know why... + +1.4. Save boot monitor program *IMPORTANT* + Upload boot monitor program from board to file. + boot monitor program starts at 0xFFF00000 + +1.5.
