Dear Sir,
I am tring to find how to initialize additional BSD driver after
calling rtems_bsd_initialize().
For example for i.MX7D case.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
< original code from nexus-devices.h >
RTEMS_BSD_DEFINE_NEXUS_DEVICE(ofwbus, 0, 0, NULL);
SYSINIT_DRIVER_REFERENCE(simplebus, ofwbus);
SYSINIT_DRIVER_REFERENCE(ffec, simplebus);
SYSINIT_DRIVER_REFERENCE(ukphy, miibus);
SYSINIT_DRIVER_REFERENCE(imx51_gpio, simplebus);
SYSINIT_DRIVER_REFERENCE(sdhci_fsl, simplebus);
RTEMS_BSD_DRIVER_MMC;
< Modified code from nexus-devices.h >
RTEMS_BSD_DEFINE_NEXUS_DEVICE(ofwbus, 0, 0, NULL);
SYSINIT_DRIVER_REFERENCE(simplebus, ofwbus);
//SYSINIT_DRIVER_REFERENCE(ffec, simplebus);
//SYSINIT_DRIVER_REFERENCE(ukphy, miibus);
SYSINIT_DRIVER_REFERENCE(imx51_gpio, simplebus);
SYSINIT_DRIVER_REFERENCE(sdhci_fsl, simplebus);
RTEMS_BSD_DRIVER_MMC;
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
It means that after BSD driver for SDHC only is initialized by calling
rtems_bsd_initialize(), I want to initialize BSD driver module about
ffec, ukphy in other thread.
Is there a method for this ?
Yes, you can call the bus API functions for device probe, attach,
detach, etc. yourself. See file rtems-kernel-bus-root.c.
