About: SPI Boot Pins & UART Port Selection

According to section 4 of documentAN-B-001DA14580 Booting from Serial Interface看来,只有一个选项to boot from SPI, which uses P0.0, P0.3, P0.5 and P0.6.

I do not konw if this is really the only option for SPI booting. And, will this option be problematic for downloading my progam into my SPI-Flash, if I use UART pins P0.0 and P0.1, and SmartSnippets Toolbox V5.0.6.2196?

Hi lewuyouc,

Thanks for your question. I think that you have already created a similar post regarding the boot up issue. Could you please check my answer on the below forum thread?

If you would like to boot from different pins than the standard, you should use the secondary bootloader.

Thanks, PM_Dialog
