Hi Dialog.
I'm using a DA14580 Development Kit - Expert with DA15480_CB_PXI_WLCSP...
I wrote an Otp Header with the address 0x47f00 and 0x47f0a with YES value.
From that point I alway have in the SmartSnippet tool that value grayed, and not possible to change.
我也失去了t的功能he "Booter" tab via UART, because it does not detect the pressing of the reset button.
I think because the OTP configuration remove the Bootmode.
Could I download a new default OTP Header in order to have again the functionality of the uart booter ? (with jtag i can use the unit)
If Yes, where I can find that OTP file ?
In attach my otp Header read from the system with the "read from memory" button

Hi fontamiHw,
After the application flags are enabled you will not be able to boot via UART. Also since you 've burned the OTP header you can't re-burn a new OTP header file.
Thanks MT_dialog
Thanks for the prompt answer.
One more simple question.
The same is for the custom image on the OTP ROM ?
Once the first is burned I cant write an update, or change the program a second time ?
Thank in advance, Mik
Hi fontamiHw,
Yes, OTP stands for One Time Programmable you can program the OTP only once. The only thing you can do with the OTP is to flip the un-written bits from 1 to 0.
Thanks MT_dialog
I understand.
Thank for your prompt answer, this help me a lot
Mik
