Hi expert,

In TRM there is example of Zero Boot Mode Select Pins, but is there any ready or simple-to-use example demo code?

Hi Joyce,

I'm not aware of an example that uses Zero BMSPs, but can reach out to our bootloader expert for further information.

Thanks and regards,

Charles

Hi Joyce,

No, there are no examples in C2000Ware, but it can easily be emulated using the emulation boot registers(at 0xD00). You can also use the DCSM tool in SysConfig to easily configure the OTP for zero-pin boot.

Best,
Matt

Hi Matt,

Thanks for reply. The challenge here is the PCB is boxed into the end product so the emulation could not achieve. Customer is thinking using the 2nd time Boot, is there any possible way for this changing to zero boot mode? Possibly with flash API or something?

Hello,

What do you mean by 2nd time boot? Do you mean that they already programmed boot configurations in Zone 1 of the DCSM?

Yes, they can use the flash API to program the BOOTPIN-CONFIG and BOOTDEF registers, please refer to Section 5.5 in SPRUJH3 for an example.

Best,
Matt
