blocked task for 3 seconds

Paul Yip

Hi,

If I want to run a blocked task e.g. write 1MB data to the external flash size 8MB(NVRAM), that it takes 3 seconds. What is the best way to to in NRF 51822?

Do you think we could wrap pstorage for external flash?

For the communication protocol, we use GPIO simulate SPI and yes we use softdevice 1.0.

Thanks.

Paul

    It's blocked what a long read e.g. 3 second read from NVRAM. If I use pstorage, it should be done async, i.e. call pstorage_update and wait for callback event PSTORAGE_UPDATE_OP_CODE.

    I'm not sure whether it could be done on an external flash if the interface is SPI over GPIO. The "SPI over GPIO" was told by my colleague. I'm not that low level of firmware engineer. I'll check with my colleague whether we could use SPI directly.
