[libbsd 0/4] Replace LPC Ethernet interface driver
The standard FreeBSD MII support causes severe problems on the LPC3200 chip family. If an Ethernet module register is accessed while there is no clock from the PHY, the chip completely locks up and only an external watchdog can recover from this state. The legacy driver had a custom PHY management code which helped to avoid such issues. The if_lpe.c driver is no longer maintained by FreeBSD. Sebastian Huber (4): if_lpe.c: Import legacy LPC Ethernet driver if_lpe.c: Port to LibBSD if_lpe.c: Move transmit initialization if_lpe.c: Use interface transmit rtemsbsd/sys/arm/lpc/if_lpe.c| 2860 +- rtemsbsd/sys/arm/lpc/if_lpereg.h | 210 --- 2 files changed, 1602 insertions(+), 1468 deletions(-) delete mode 100644 rtemsbsd/sys/arm/lpc/if_lpereg.h -- 2.35.3 ___ devel mailing list devel@rtems.org http://lists.rtems.org/mailman/listinfo/devel
