C5402 DSK external memory - Doreen Yeo Lee Guek - Nov 24 7:34:00 2000

Good day. Happy Thanksgiving to those cebrating this occassion! From the CPLD control register 2, the FLASHENB bit will determine whether the external memory is FLASH or SRAM. Does that mean that FLASH & SRAM cannot be enable at the same time? FLASH has a 7 wait-state latency & SRAM has a 1 wait-state latency. Upon power up, i like to copy the program from FLASH to SRAM so that the on-chip DARAM can be utilise. Any suggestion? Thanks & regards, Doreen |

You could copy a block at a time from Flash to internal DARAM, flip the FLASHENB bit, and copy the block from DARAM to SRAM. This is the only way I can think of doing it.
