In this guide, we will step-by-step guide you to use OPTTool (a software application) to burn OTP bits on SP7350 platforms.
...
If the options are not enabled, enable them and save the changes. Run the command ‘make' in the project’s top directory to rebuild the code.
Additionally, ensure that the OTP_1V8 power pin of the SP7350 is supplied with 1.8V to allow OTP programming. For example, in the schematic below:
...
Mount R441 with a 0Ω resistor to supply the necessary 1.8V power for writing OTP bits.
