<CC2640> Could CC2640 boot from external SPI flash?

Other Parts Discussed in Thread: CC2640

Hi Sir,

For mass production cost issue (To avoid programming F/W two times and reducing code size if implemented PTM in CC2640), I have an idea that is let CC2640 boot  from external SPI flash, which pre-burn  an image, just like "HostTest", and it will run into DTM for RF testing. 

Besides, CC2640 could resume to normal application code (internal flash) at normal mode. Dose is work? if the concept is right, how I suppose to do?

    Hi Issac,

    Unfortunately I don't think it is feasible. If an image needs to be runnable, it should be located in the internal flash memory. You can copy the image you want to run from the external flash memory into the internal flash memory though. However, it requires a boot loader doing that kind of job.
