External flash mx25l2564 issue with stm32 Nucleo_h723zg

[tejueaton]

Hi All,

I am interfacing the external flash mx25l2564 with nucleo_h723zg in Zephyr version 3.2 , Have connected the external flash Qspi in MCU,
Since in stm32h723vgtx-pinctrl.dtsi file those pins are mapped to octospi pins I have added this in my dts file ,

&octospi1{
pinctrl-names = "default";
pinctrl-0 = <&octospim_p1_clk_pb2 &octospim_p1_ncs_pb6
&octospim_p1_io0_pc9 &octospim_p1_io1_pc10
&octospim_p1_io2_pe2 &octospim_p1_io3_pd13>;
status = "okay";

mx25l2564: mx25l2564@0 {
    compatible = "st,stm32-ospi-nor";
    reg = <0>;
    ospi-max-frequency = <8000000>;
    size = <DT_SIZE_M(256)>; /* 32 MBytes */
	data-rate = <OSPI_STR_TRANSFER>;
    status = "okay";
    spi-bus-width = <4>;
    writeoc = "PP_1_4_4";
	sfdp-bfp = [
		53 46 44 50 06 01 02 ff
		00 06 01 10 30 00 00 ff

	];
	partitions {
		   compatible = "fixed-partitions";
		   #address-cells = <1>;
		   #size-cells = <1>;

		   partition@0 {
		       reg = <0x00000000 DT_SIZE_M(32)>;
		   };
	};
};

};

and also have added these below lines in stm32h723.dtsi file.

clock-names = "ospix", "ospi-ker", "ospi-mgr";
            clocks = <&rcc STM32_CLOCK_BUS_AHB3 0x00004000>,
                <&rcc STM32_SRC_PLL1_Q OSPI_SEL(1)>,
                <&rcc STM32_CLOCK_BUS_AHB3 0x00200000>;

Getting error in running flash_shell sample writing and erasing to the flash.
Below is the output which i am getting :

Environment : nucleo_h723zg board with QSPI mx25l2564 NOR flash connected on the CN10
Define the octospi1 node in the DTS with corresponding pinout :

Converting to discussion until it is confirmed that issue is a genuine driver bug (potential dts config issue)

Hi @FRASTM ,
I am trying to run the smp_svr example for firmware upadte from external flash,

But after executing mcumgr image list, getting only one image, Slot-1 image is not showing at all.

mcumgr -c COMPORT image list
Images:
image=0 slot=0
version: 0.0.0
bootable: true
flags: active confirmed
hash: eae7c4e6eb9bxxxxxxxxxxe28e18a7c042ede93fe9d34fc5727ebdf8f324547c375
Split status: N/A (0)

below is the settings which i have done.

&octospi1{
pinctrl-names = "default";
pinctrl-0 = <&octospim_p1_clk_pb2 &octospim_p1_ncs_pg6
&octospim_p1_io0_pd11 &octospim_p1_io1_pd12
&octospim_p1_io2_pe2 &octospim_p1_io3_pd13>;
status = "okay";

mx25l2564: mx25l2564@0 {
    compatible = "st,stm32-ospi-nor";
    reg = <0>;
    ospi-max-frequency = <8000000>;
    size = <DT_SIZE_M(256)>; /* 32 MBytes */
	data-rate = <OSPI_STR_TRANSFER>;
    status = "okay";
    spi-bus-width = <4>;
    writeoc = "PP_1_4_4";
	partitions {
    compatible = "fixed-partitions";
    #address-cells = <1>;
    #size-cells = <1>;

   slot1_partition: partition@0 {
               reg = <0x00000000 DT_SIZE_K(256)>;
    };

    ext_dcinv: partition@40000 {
			   label = "ext_dcinv";
               reg = <0x00040000 DT_SIZE_M(4)>;
    };

    extra_partition: partition@440000 {
                reg = <0x0044000 DT_SIZE_M(1)>;
    };
};

};
};

And below is the nucleo_h723zg.overlay file used for mcuboot in board folder,

    };

    slot0_partition: partition@20000 {
        label = "image-0";
        reg = <0x00020000 DT_SIZE_K(256)>;
