LPC55S69 SPI Flash Recovery Boot Configuration

Hello,

I am trying to configure the SPI Flash Recovery Boot on the LPC55S69. Documentation points to bits 3:0 in the CMPA (Address 0x9E404), but does not specify what these bits need to be. I tried 0x00 through 0x0F and the bootloader did not load the SB2.1 file I wrote to address 0x0 on my connected SPI Flash.

Could you provide some documentation as to how one should configure the LPC55S69 to load an SB2.1 image from SPI Flash?

Thank you,

Alex

Hello Alex,

 

"if SPI_RECOVERY_BOOT_EN not '0000' then enable SPI recovery.

And do you use LPC55s69-EVK board? If yes, there is no external flash in board.

 

Regards,

Alice
