Question:
How to program flash ROM of EV-21569-SOM?
Answer:
The ADSP-2156x boot ROM does not directly support flash programming.
Try to flash EV-21569-SOM board using, CrossCore Serial Flash Programmer (CCSFP).
CrossCore Serial Flash Programmer (CCSFP) is a standalone application for programming, erasing and re-programming the on-board flash of mixed-signal processors, via the UART interface.
