3rd chip EBYTE_E73 with nrf52840 core fail use SPIFBlockDevice as secondary slot

[wangleifool]

Hi George,

Thanks for the hard work on this project, it's give me huge help.

It was success on my nrf52840-DK board with FLASHIAP follow your guide，I change to use 3rd chip EBYTE_E73 with nrf52840 core, And try to use SPIFBlockDevice as secondary slot. The SPIFBlockDevice is work fine when mcuboot is not integrated. But after I integrated the MCUboot , SPIFBlockDevice init always return -4002 error code.

Can you give some advice ? thanks very much.
