I have a custom board (NXP iMX6UL) with Spansion Flash 25HS512TFANHI010 which I cant seem to get working.
My dtsi has the following
...
pinctrl_qspi: qspigrp {
fsl,pins = <
MX6UL_PAD_NAND_WP_B__QSPI_A_SCLK 0x70a1
MX6UL_PAD_NAND_READY_B__QSPI_A_DATA00 0x70a1
MX6UL_PAD_NAND_CE0_B__QSPI_A_DATA01 0x70a1
MX6UL_PAD_NAND_CE1_B__QSPI_A_DATA02 0x70a1
MX6UL_PAD_NAND_CLE__QSPI_A_DATA03 0x70a1
MX6UL_PAD_NAND_DQS__QSPI_A_SS0_B 0x70a1
>;
};
...
&qspi {
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_qspi>;
status = "okay";
//cs-gpios = <&gpio4 16 0>;
flash0: s25hs512t@0 {
#address-cells = <1>;
#size-cells = <1>;
compatible = "spansion,s25hs512t", "jedec,spi-nor";
spi-max-frequency = <40000000>;
spi-rx-bus-width = <4>;
spi-tx-bus-width = <4>;
reg = <0>;
spi-mode = <0>;
spi-cpha;
spi-cpol;
m25p,fast-read;
//wp-gpios = <&gpio4 14 0>;
//hold-gpios = <&gpio4 15 0>;
status = "okay";
};
};
For u-boot my defconfig has the following
CONFIG_DM=y
CONFIG_SPI=y
CONFIG_SPI_FLASH=y
CONFIG_SPI_FLASH_SPANSION=y
CONFIG_DM_SPI=y
CONFIG_DM_SPI_FLASH=y
CONFIG_FSL_QSPI=y
CONFIG_SF_DEFAULT_MODE=0
for linux my defconfig has basically (among a lot of other stuff)
CONFIG_SPI_FSL_QUADSPI=y
so both u-boot and Linux doesn't seem to work well

I have tried almost every iteration possible, but I can seem to get to the issue. I have a feeling its something to do with the dtsi. Any help will be appreciated, am at wits end.
PS: tried the cypress forums but they have been very non responsive. they have a u-boot patch from 2018.01 which is as such not compatible with 2021.10
Support for S25HL/S25HS series has been added in u-boot 2021.10-rc3.
Ensure:
CONFIG_SPI_FLASH_SFDP_SUPPORT is set and
CONFIG_SPI_FLASH_BAR is not set
Thanks to Mr. Kuwano of Infineon for the support.
PS: Not tested on Linux. Not working on Barebox yet (getting detected but not writing).
