Hello.
We are developing a device that require a 1Gb qspi memory interafaced with a nrf52840.
So far the qspi driver and the memory inits and the memory respond to some commands, but fail in anothers.
Taking a look to the instruction data set for both devices (qspi hardware on the chip and command set of the memory) i found out that some instructions are diferent.
From issi datasheet.
From driver specs for the qspi hardware at infocenter
I been looking to update the instruction data set of the qspi driver on the sdk but does not find were this data set is defined.
1. Could you please tell me where can I take a look to this values to modify them?
2. Could you recommend a memory device with 1Gb and qspi interface that work directly with your actual driver implementation? The external flash memory on the DK works great but does not fit the capacity of our project.
Kind regards.
Edén Candelas.
