Hi,
I am working on imx8qxp B0 and yocto 5.4.47 release.
I try to change the pin muxing of QSPI, FLEXCAN and use as GPIO and UART0_RTS respectively from the uboot and kernel, but it can not set as expected.
i go through the SCFW_1.6.0 source code and found that there are below code
/* Move some pads not in the M4_0 subsystem */
BRD_ERR(rm_set_pad_movable(pt_boot, SC_P_FLEXCAN0_RX,
SC_P_FLEXCAN2_TX, SC_TRUE));
BRD_ERR(rm_set_pad_movable(pt_boot,SC_P_USB_SS3_TC1,
SC_P_USB_SS3_TC1, SC_TRUE));
BRD_ERR(rm_set_pad_movable(pt_boot,SC_P_USB_SS3_TC3,
SC_P_USB_SS3_TC3, SC_TRUE));
BRD_ERR(rm_set_pad_movable(pt_boot, SC_P_QSPI0A_DATA0,
SC_P_COMP_CTL_GPIO_1V8_3V3_QSPI0B, SC_TRUE));
I have change in above code from SC_TRUE to SC_FALSE and it working fine.
I want know, which is the valid way to make all this type of resource access available for uboot and kernel from SCFW?
Regards,
Darshak
