Not able to initalize the QSPI module.

[Rajat]

Hi Everyone

*ITS VERY URGENT ISSUE*.

I am using nrf52840 PDK with segger embedded IDE. 

I was trying to use the QSPI module to write data to the external flash memory.

But I am not able to initialize the QSPI module.

It throws error "NRF_TIMEOUT_ERROR" after the init function is called.

What is the reason for this problem and how can it be solved.

Following are the linker section placement macros : 

FLASH_PH_START=0x0

FLASH_PH_SIZE=0x100000

RAM_PH_START=0x20000000

RAM_PH_SIZE=0x40000

FLASH_START=0x26000(My code is running BLE alongwith FREERTOS)

FLASH_SIZE=0x100000

RAM_START=0x20002A98

RAM_SIZE=0x3D568

If any other information is required , please revert back.

Thanks!

Here is the code that i have been using

[Jørgen Holmefjord]

Which functioncall is returning NRF_TIMEOUT_ERROR? I can't see this error code used in the QSPI driver. Which QSPI device are you interfacing? Have you checked that the connections are correct?

Which SDK version are you using? I would recommend that you switch to using the nRF52840-DK.

[Rajat]

I am using 15.0 version of SDK. 

nrf_drv_qspi_init() function is throwing error. 

I am using nrf52840 PDK and QSPI device is the onboard external memory of 64Mb( mx25R6435F ,  , so the connections would be correct ).

[Jørgen Holmefjord]

Did you test the QSPI Example from the SDK, to make sure the board/device is working as expected?

[Rajat]

Yes example code is working fine.
