Can offline programming encrypt the chip like the NuMicro ICP Programming Tool?
Posted: 31 May 2021, 16:00
Yes, the principle and process of offline programming are as follows:
(1) Download the binary file from the PC to a device with offline flash, such as Nu-Link or Nu-Link-Pro;
(2) Remove the device with offline Flash from the PC;
(3) Connect the device with offline Flash to the chip to be updated for programming.
Since the offline Flash stores information for updating the chip and Config settings, if the content written to the offline Flash has the encryption function in Config enabled, when the target chip is programmed offline, the Config of the target chip is also updated to the state where the encryption function is enabled.
