LS1046A custom board QSPI flash read/write not working

humhh — Wed, 29 Mar 2023 16:18:33 GMT

Hello all:

Our LS1046a custom board use one QSPI A and flash s25fs512,in uboot stage,it can detect,but read or write not working.

when spi-rx-bus-width/spi-tx-bus-width is 1,read back is all 0; when spi-rx-bus-width/spi-tx-bus-width is 4,read back is all 0xEE,I don't know what and where is the root cause, thanks.

sf probe 0:0

SF: Detected s25fs512s with page size 256 Bytes, erase size 256 KiB, total 64 MiB

&qspi {
status = "okay";

s25fs512: flash@0 {
#address-cells = <1>;
#size-cells = <1>;
compatible = "jedec,spi-nor";
spi-max-frequency = <20000000>;
reg = <0>;/*
spi-rx-bus-width = <4>;
spi-tx-bus-width = <4>;*/
status = "okay";
};
};

Hello,

you can try the QSPI verification in U-boot/linux provided in LSDK 21.08, in chapter 7.2.9 Quad Serial Peripheral Interface (QSPI)
