Use Flash Memory on SPI bus

[Irfan Memon]

WI-FI_Flash _RESET & LED.pdfHi,

We have two option to use Flash memory,

Option 1:
We are planning to use Flash Memory on the SPI bus shared with the NRF7002. Kindly confirm whether this configuration is feasible.

Option 2:
We have the following GPIOs available for use: P2.00, P1.03, P3.04, P0.03, P0.04, and P0.06.

Thanks & Regards,

Irfan

Hello,

We are planning to use Flash Memory on the SPI bus shared with the NRF7002. Kindly confirm whether this configuration is feasible.

Can you please confirm which host is being used? According to some similar previous cases, this is not supported and SPI/QSPI peripheral cannot be shared with other devices including external flash memory. It needs its own SPI bus. You can use a separate SPI bus for the flash memory with available GPIOs. I would recommend you to take a look at the following documentation: External Memory
