Writing External Flash QSPI

[Om Trivedi]

I have an external flash 

S25FL132K

I am able to read , write and erase the flash with nrfx_qspi_cinstr_xfer function for 9 bytes. But I want to write more than 9 bytes(NRF_QSPI_CINSTR_LEN_9B) of data so I tried using nrfx_qspi_write and nrfx_qspi_cinstr_xfer both but not able to write more than 9 bytes(1 byte of opcode + 3 bytes address + 5 bytes data) into flash !

Can someone help ASAP!!

Hi Om,

You could take a look at the long frame mode ( nrfx_qspi_lfm_xfer ) in the QSPI driver. This could help in implementing custom byte length.
