Booting on FLEXSPI Port A with S26KS512S from MIMXRT685SFVKB

[daiki]

I'm having trouble booting.

The ISP pin settings are correct.

How do I configure OTP and configure FCB to boot MIMXRT685SFVKB with FLEXSPI Port A using S26KS512S?

Thanks.

Hi @daiki ,

   S26KS512S is the hyperflash, and you connect to the flexspi A port.

ISP need to be:

Can you try to use the MCUbootUtility tool to connect your board in the ISP mode?

the related user manual is:

Whether the connection will be OK or not?

I think, you don't use the OTP at first, just test it at first, whether it works or not, as the option0 and option1 can define the flash type, you can check RT600 UM chapter 41.5.1.5.2 FlexSPI NOR flash config parameters

Best Regards,
