openMSP430

Hello,

it is possible to deactivate the Memory access (CEN=1) in the reset state of the OMSP430. Backgorund, in an ASIC project we have to prepare the OMSP Memory implementation, and it is easier to this, when the MSP430 doesn't lock the memory via the CEN signal. Exists special reasons to do that in the other way (RST_N='0' -> CEN='0')?

Best Regards, Andreas

Hi Andreas,

In order to update the memory prior startup, I would recommend to use the DMA interface.

In particular, you can check-out the bootloader section: https://opencores.org/project,openmsp430,dma%20interface#3.5.2%20Bootloader%20case
