8.12.5.1. Boot Image Generation#

The application executable file (ELF file) must be converted to a boot image. Use the following commands:

powerpc-rtems6-objcopy -O binary -R .comment -S ticker.exe rtems
gzip -9 -f rtems
powerpc-rtems6-ld -o ticker.boot bootloader.o --just-symbols=ticker.exe -b binary rtems.gz -T ppcboot.lds -no-warn-mismatch
powerpc-rtems6-objcopy -O binary ticker.boot ticker.bin

8.12.12. qoriq (QorIQ)#

The BSP for the QorIQ chip family offers three variants. The qoriq_e500 variant supports the P-series chips such as P1020, P2010 and P2020. The qoriq_e6500_32 (32-bit ISA) and qoriq_e6500_64 (64-bit ISA) variants support the T-series chips such as T2080 and T4240. The basic hardware initialization is not performed by the BSP. A boot loader with device tree support must be used to start the BSP, e.g. U-Boot.

The BSP is known to run on these boards:

  • NXP P1020RDB

  • MicroSys miriac MPX2020 (System on Module)

  • Artesyn MVME2500 (VME64x SBC)

  • NXP T2080RDB

  • NXP T4240RDB

  • MEN G52A (CompactPCI Serial)

The qoriq_core_0 and qoriq_core_1 variants should be used with care. They are inteded for a RTEMS_MULTIPROCESSING configuration on the P1020.

8.12.12.1. Boot via U-Boot#

The application executable file (ELF file) must be converted to an U-Boot image. Use the following commands:

powerpc-rtems6-objcopy -O binary app.exe app.bin
gzip -9 -f -c app.bin > app.bin.gz
mkimage -A ppc -O linux -T kernel -a 0x4000 -e 0x4000 -n RTEMS -d app.bin.gz app.img

Use the following U-Boot commands to boot an application via TFTP download:

tftpboot ${loadaddr} app.img && run loadfdt && bootm ${loadaddr} - ${fdt_addr} ; reset

8.12.12.2. Clock Driver#

The clock driver uses two MPIC global timer (QORIQ_CLOCK_TIMER and QORIQ_CLOCK_TIMECOUNTER). In case QORIQ_IS_HYPERVISOR_GUEST is defined, then the PowerPC decrementer is used.

8.12.12.3. Console Driver#

The console driver supports the on-chip NS16550 compatible UARTs. In case QORIQ_IS_HYPERVISOR_GUEST is defined, then the EPAPR byte channel is used for the console device.

8.12.12.4. Network Interface Driver#

The network interface driver is provided by the libbsd. The DPAA is supported including 10Gbit/s Ethernet.

8.12.12.5. Topaz Hypervisor Guest#

For a Topaz hypervisor guest configuration use:

../configure --enable-rtemsbsp=qoriq_e6500_32 \
    QORIQ_IS_HYPERVISOR_GUEST=1 \
    QORIQ_UART_0_ENABLE=0 \
    QORIQ_UART_1_ENABLE=0 \
    QORIQ_TLB1_ENTRY_COUNT=16

You may have to adjust the linker command file according to your partition configuration.
