Dear Huber,
I think that you have focused RTEMS version for i.MX7D board until now.
i.MX6Q SDP board is arrived. and, I am doing porting work about RTEMS for
i.MX6Q SDP board with u-boot.
After internal work is completed, I will open my RTEMS porting version for
i.MX6Q.
At this time, I did boot RTEMS in u-boot console according to below step in my
case.
- fatload mmc 1 0x18000000 imx6q-sabresd.dtb
- fatload mmc 1 0x10100000 rtems.bin
- go 0x10100000
On referencing, I am not expert regarding u-boot configuration for booting
RTEMS.
Because I don't know how to transfer DTB block address(0x18000000) in u-boot, I
modified start.S tentatively as like below;
#ifdef BSP_START_COPY_FDT_FROM_U_BOOT
#ifdef RTEMS_SMP
cmp r7, #0
bne 1f
#endif
// mov r0, r6
mov r0, #(0x18000000)
bl bsp_fdt_copy
1:
#endif
If possible, please let me know how to transfer DTB block address in u-boot on
your i.MX7D board.
On referencing, current progress is below;
1) RTEMS kernel for single core : completed.
2) FAT file system for SD card : completed.
3) RTEMS kernel for Quad multi-core : on-going.
- There is possibility for failing SMP port.
- Maybe, I need some helps from RTEMS users.
4) RTEMS libbsd for Network : on going.
If #4(libbsd for Network) is ported, I will process to open my RTEMS version.
Best Regards,
JunBeom Kim

I added the i.MX 7Dual network interface driver to libbsd today. There are some
performance issues:
