Hello,


I try to install W25Q128 Winbond (serial flash memory) on SPI pin and with /CS W25Q128 on SPI_CS1 (pin 27).

On W25Q128 , Pins WP and reset/Hold aren't connected.
MISO, MOSI and clk on EXT3 [ 5 6 7 ] rt5350f' pins.


  • DTSI file

I have split spi definition on RT5350 DTSI file  :

Code (rt5330.dtsi) Select

spi@b00 {
compatible = "ralink,rt5350-spi", "ralink,rt2880-spi";
reg = <0xb00 0x40>;

resets = <&rstctrl 18>;
reset-names = "spi";

#address-cells = <1>;
#size-cells = <1>;

pinctrl-names = "default";
pinctrl-0 = <&spi_pins>;

status = "disabled";
};

spi@b40 {
compatible = "ralink,rt5350-spi";
reg = <0xb40 0x60>;

resets = <&rstctrl 18>;
reset-names = "spi";

#address-cells = <1>;
#size-cells = <1>;

pinctrl-names = "default";
pinctrl-0 = <&spi_cs1>;

status = "disabled";
};



  • DTS file

Add SPI section on Olimex DTS file :

Code (OLINUXINO-RT5350F.dts) Select

spi@b40 {   
status = "okay";   
           
m25p80@0 {
#address-cells = <1>;
#size-cells = <1>;
compatible = "w25q128";
reg = <0 0>;
linux,modalias = "m25p80", "w25q128";
spi-max-frequency = <104000000>;

partition@0 {
label = "data";
reg = <0x0 0x8000000>;
};
};
           
           
};


  • rt305x.c

patch rt305x.c for Clock declaration :

Code (rt305x.c) Select

+ ralink_clk_add("10000b40.spi", sys_rate);


But, i have few errors ...  ??? .... :'(

I fix Nor flash on SPI connectique with another config :


Code (rt5350.dtsi) Select

i change reg rules like this :
Code (OLINUXINO-RT5350F.dts) Select

m25p80@1 {
                       
                                #address-cells = <1>;
                                #size-cells = <1>;
                                compatible = "w25q128";
                                reg = <1 0x800000 0x1000000>;
                                linux,modalias = "m25p80", "w25q128";

spi-max-frequency = <10000000>;

partition@0 {
label = "home ";
reg = <0x0 0x1000000>;
};
};


it's work , without err/warning message on boot ...

... like "home" start to 0x000000800000 , or it's a new device with new register ? ... oO


So, where i can define mtd partion or fix mount after the boot system ?!

I find an issu on VoCore Blog : VoCore: SPI & MicroSD 11

...  Thx Lub !!!


as a previous post : VoCore: SPI & MicroSD 6 ... devices and SPI pin need a Pull High or Pull up connection !

also pull HOLD/WP to high

So, i add on FSTAB config few line :
Code Select

config 'mount'
        option  target  '/mnt/data'
        option device '/dev/mtdblock7'
        option label    'data'
        option  fstype  'jffs2'
        option 'options'  'rw,noatime'
        option  enabled '1'


Each start , MTD7 block was mount on mnt :

Next step : clean the openwrt squashfs image between : spi tools , Flash tools and other MTD's family modules installed for testing.
And up FSTAB config on openwrt source for build a good image.

FiXED !!! ... :)

i change iles like that :

Code (OLINUXINO-RT5350F.dts) Select


/dts-v1/;

/include/ "rt5350.dtsi"


/ {
        compatible = "RT5350F-OLINUXINO", "ralink,rt5350-soc";
        model = "RT5350F-OLINUXINO";

        palmbus@10000000 {

   
spi@b00 {   
status = "okay";   

                        m25p80@0 {
                                #address-cells = <1>;
                                #size-cells = <1>;
                               
                               ...........

                        };

m25p80@1 {
#address-cells = <1>;
#size-cells = <1>;
compatible = "w25q128";
reg = <1>;
linux,modalias = "m25p80", "w25q128";

spi-max-frequency = <10000000>;

partition@0 {
label = "userdata";
reg = <0x0 0x1000000>;
};
};

                           
                               ...........   




Code (rt5350.dtsi) Select


spi@b00 {
compatible = "ralink,rt5350-spi","ralink,rt2880-spi";
reg = <0xb00 0x100>;

resets = <&rstctrl 18>;
reset-names = "spi";

#address-cells = <1>;
#size-cells = <1>;

pinctrl-names = "default";
pinctrl-0 = <&spi_pins &spi_cs1>;

status = "disabled";
};




Dont forget to plug "WP" and "Hold" pins on a 3.3v (pull high)


and I up thr FSTAB file /openwrt/package/system/fstools/files/fstab.default :


Code (fstab.default) Select



if [ -f i/dev/mtdblock7 ]
echo "Formatage du block MTD7 en jffs2 (no skip bad blocks)"
flash_eraseall -jN /dev/mtd7
then
echo "ERROR : mtdblock7 not FOUND"
fi


if [ ! -f /etc/config/fstab ]
then
echo "Detection des block"
block detect > /etc/config/fstab

echo "ecriture du montage SOLDIOM"
   
echo " " >> /etc/config/fstab
echo "##SOLIDOM external Mount" >> /etc/config/fstab
echo "config 'mount'" >> /etc/config/fstab

echo " " >> /etc/config/fstab
echo " " >> /etc/config/fstab

else
   echo "FSTAB already in config"
fi

exit 0



SPI FLASH needed a formatting JFFS2 type. So , i write flash_erase on Openwrt install step.







  • After the OpenWrt flash ( 2: Load system code then write to Flash via TFTP.), a reboot was need for good mtdblock7 mount
  • I wait few second after the reboot for release mount
  • Check for good size like 16384 Kbytes on booting log

with this UCI commit, you are no erase data on SPI flash after a "firstboot & reboot" .


But, on first flash , the mount/detect finished before the "flash_eraseall". So, may be reboot ralink for good mount.
