This weekend, I install JetPack 2.1 (R23.2), and I can install pkgsrc u-boot successfully with flash.sh -k EBT.
	https://sacraya.610t.org/TX1/boot/flash.sh_NetBSD-uboot-dtb.bin.EBTwithR23.2.20180617.txt

I think that it works fine, 
	https://sacraya.610t.org/TX1/boot/dmesg_NetBSD.NetBSD_u-boot.EBTwithR23.2.20180617.txt
  but I can’t boot NetBSD yet because of "bootconfig.dramblocks <= DRAM_BLOCKS” problem.

	[   1.0000000] panic: kernel debugging assertion "bootconfig.dramblocks <= DRAM_BLOCKS" failed: file "/home/source/ab/HEAD/src/sys/arch/aarch64/aarch64/aarch64_machdep.c", line 198

	.insn   0x00000000      # undefined

This problem is same as when I used original u-boot.

Which does it mean ...
	I must set some more u-boot environment correctly?
	I must create more appropriate kernel config and use it?
	
Thanks.
