| 50 | 65 | |
| 51 | 66 | Usually, a FLASH chip is included. During the debugging phase, code is programmed into the FLASH, allowing for repeated debugging and programming. The SDK also provides library files for booting the chip from FLASH. You just need to configure the relevant macro definitions, which is very convenient, as shown in the figure below. Once the code is stable and the product is ready for mass production, the FLASH can be removed, and the code can be programmed into the OTP memory. (PS: This is probably why the DA14585 is cheaper than Nordic.) |
