Hello, kindly ask for help about SPI at an IMX8MP. I tried latest 2023.01. If you can please have a look and check it works on your side?

sspi command returns: Invalid bus 0

Turning on the log-level:

drivers/core/lists.c:201- lists_bind_fdt() bind node spi@30820000 drivers/core/lists.c:222- lists_bind_fdt() - attempt to match compatible string 'fsl,imx8mp-ecspi' drivers/core/lists.c:222- lists_bind_fdt() - attempt to match compatible string 'fsl,imx51-ecspi' drivers/core/lists.c:250- lists_bind_fdt() - found match at 'mxc_spi': 'fsl,imx51-ecspi' matches 'fsl,imx51-ecspi'

u-boot=> sspi drivers/core/uclass.c:338-uclass_find_device_by_seq() 0 drivers/core/uclass.c:346-uclass_find_device_by_seq() - 1 'spi@30820000' drivers/core/uclass.c:353-uclass_find_device_by_seq() - not found drivers/spi/spi-uclass.c:431- _spi_get_bus_and_cs() Invalid bus 0 (err=-19)

What am I doing wrong or is this a bug? Thanks ahead for any hint.

Best regards, Elmar

Pretty sure my config and devicetree is not wrong as long there are no changes about in last few month. I attache it below.

my config file: CONFIG_SPL_DM_SPI=y CONFIG_CMD_SPI=y CONFIG_SPI=y CONFIG_DM_SPI=y CONFIG_MXC_SPI=y

dt: (tested with both types of cs-gpios) &ecspi1 { pinctrl-names = "default"; pinctrl-0 = <&pinctrl_ecspi1>; cs-gpios = <0>, <&gpio5 9 GPIO_ACTIVE_LOW>; // cs-gpios = <&gpio5 9 GPIO_ACTIVE_LOW>; status = "okay"; };

pinctrl_ecspi1: ecspi1grp { fsl,pins = < MX8MP_IOMUXC_ECSPI1_MISO__ECSPI1_MISO 0x00000104 MX8MP_IOMUXC_ECSPI1_MOSI__ECSPI1_MOSI 0x00000104 MX8MP_IOMUXC_ECSPI1_SCLK__ECSPI1_SCLK 0x00000104 MX8MP_IOMUXC_ECSPI1_SS0__GPIO5_IO09 0x00000104 >; };
