Cannot use QSPI between nrf54LM20DK and nrf7002-EBII

[Muhammad Abdullah Jean]

Dear nordic support team,

Hi! Wish you have a good day.

I am currently using the nRF54LM20 DK, which has the nRF54LM20B MCU. I would like to use the EXP pins to connect an external nrf7002-EBII expansion board for high speed wifi connection.

The issue is that communication between the expansion board and the main board currently supports SPI, but not QSPI. As far as I know, Nordic has not released a QSPI driver for this platform yet. However, the nrf7002-EBII itself supports QSPI as I can see the testing point labelled 'QSPI' on the board.

Could you please let me know whether Nordic has any plan to provide official QSPI driver support for the EXP pins of nRF54LM20B in the future? That reallly helps.

Thanks for your attention!

Sincerely,

Jean

Hi,

SQSPI, when supported, will be included in this repository:

https://github.com/zephyrproject-rtos/nrf_wifi/tree/main/bus_if/bus

 

At this time, it is not present.

Unfortunately, I do not have detailed knowledge about roadmap related questions, but if you contact sales via this:

https://www.nordicsemi.com/About-us/Contact-Us

 

Then you should get in touch with personell that can help you with this.

 

Kind regards,

Håkon
