Hello,
We are using a custom board based on iMX8QXPMEK. We are using Yocto Zeus with BSP L5.4.24-2.1.0.
In this board, we have provided support for connecting two memories on the flexSPI interface similar to the below diagram from the reference manual,
In our dts file, we have added another node inside &flexspi0 as follows
ram0: abc@1 {
reg = <1>;
#address-cells = <1>;
#size-cells = <1>;
compatible = "my-driver";
spi-max-frequency = <60000000>;
spi-tx-bus-width = <8>;
spi-rx-bus-width = <8>;
};
But when the board boot-up, it shows the below error msgs
[ 1.296063] imx8qxp-pinctrl scu:pinctrl: pin IMX8QXP_QSPI0B_SCLK already requested by scu:pinctrl; cannot claim for 5d120000.spi
[ 1.307656] imx8qxp-pinctrl scu:pinctrl: pin-165 (5d120000.spi) status -22
[ 1.314553] imx8qxp-pinctrl scu:pinctrl: could not request pin 165 (IMX8QXP_QSPI0B_SCLK) from group flexspi0grp on device scu:pinctrl
[ 1.326661] nxp-fspi 5d120000.spi: Error applying setting, reverse things back
[ 1.333925] nxp-fspi: probe of 5d120000.spi failed with error -22
We are not even using IMX8QXP_QSPI0B_SCLK pins in our HW connections. Still getting these errors.
The error remains even if the flash0: mt35xu512aba@0 node is disabled.
Kindly help to resolve the issue.
Thank you.
