Qspi flash sample project error

jspiller

Hello, I am trying to use the spi_flash sample project with a laird bl654 dvk. When I run the project however, dev->state->init_res = 19 and will not run for me. It recognizes the device and if I manually set the error code to 0 the project runs correctly. Any idea why this is occurring. The output is 

JEDEC QSPI-NOR SPI flash testing
==========================
SPI flash driver MX25R64 was not found!

This is a onboard flash that supposedly should work from this post https://devzone.nordicsemi.com/f/nordic-q-a/64769/qspi-flash-sample-in-zephyr. I am using sdk 1.9.1.

    Thanks for the response,

    I just tried putting that line in, but it throws "parse error: undefined node label 'mx25r6435f'" when I try to build. I tired adding the "@0" as well. Using "/delete-node/ &spi1;" is recognized but does not seem to solve the issue. In the device tree the node does show up however, I have tried manually disabling spi1 as well, but no luck. Here is my .conf and .overlay files.

    I have not tried this on a nRF52840dk, does that board have a spi flash on it?

    Hi,

    Sorry for that, it seems that this peripheral/node isn't required to delete.

    This is the overlay and conf file that I placed in the board folder for the bl654_dvk:

    bl654_dvk.conf

    bl654_dvk.overlay

     

    The pin-outs are edited to match the nRF52840-DK, as I do not have this module at-hand.

    This ran as expected when flashed:

    *** Booting Zephyr OS build v2.7.99-ncs1  ***

Test 1: Flash erase
Flash erase succeeded!

Test 2: Flash write
Attempting to write 4 bytes
Data read matches data written. Good!!

    I just tested it on a nRF52840dk and it worked as you saw as well. It is something specific to the bl654 module then that is causing an issue. Any idea what that might be?

    Hi,

     

    Have you connected an external qspi flash or are you using the internal one on the bl654-dvk?

    Have you checked that the on-board spi flash has routed all the qspi pins?

     

    Kind regards,

    Håkon

    There is a optional external qspi that comes on the dev kit. I followed the instructions shown here:

    And configured the qspi as such:

    &qspi {
	status = "okay";
	sck-pin = <14>;
	io-pins = <9>, <13>, <12>, <11>;
	csn-pins = <16>;
	mx25r64: mx25r6435f@0 {
		compatible = "nordic,qspi-nor";
		reg = <0>;
		/* MX25R64 supports only pp and pp4io */
		writeoc = "pp4io";
		/* MX25R64 supports all readoc options */
		readoc = "read4io";
		sck-frequency = <8000000>;
		label = "MX25R64";
		jedec-id = [ c2 28 17  ];
		sfdp-bfp = [ e5 20 f1 ff ff ff ff 03 44 eb 08 6b 08 3b 04 bb ee ff ff ff ff ff 00 ff ff ff 00 ff 0c 20 0f 52 10 d8 00 ff 23 72 f5 00 82 ed 04 cc 44 83 68 44 30 b0 30 b0 f7 c4 d5 5c 00 be 29 ff f0 d0 ff ff  ];
		size = <67108864>;
		has-dpd;
		t-enter-dpd = <10000>;
		t-exit-dpd = <35000>;
	};
};

    Does this seem correct?
