Hello,
I am facing an issue of low speed of file read and write while using LFS on External Flash, Winbond (W25Q64JV) .
This is the Configuration Im using in my DTS file, Can you please guide me how to increase the efficiency of the File system?
&spi30 {
compatible = "nordic,nrf-spim";
status = "okay";
pinctrl-0 = <&spi30_default>;
pinctrl-1 = <&spi30_sleep>;
pinctrl-names = "default", "sleep";
cs-gpios =<&gpio0 1 GPIO_ACTIVE_LOW>;
w25q64: w25q64jv@0 {
compatible = "jedec,spi-nor";
reg = <0>;
spi-max-frequency = <32000000>;
jedec-id = [ef 40 17];
label = "external_flash";
size = <0x800000>; //8 Mb
has-dpd;
t-enter-dpd = <3500>;
t-exit-dpd = <3500>;
sfdp-bfp = [
