Re: How to write u-boot bootloader for Jetson TX1

I think if you are just updating U-Boot, you need to specify '-k LNX' on the flash.sh command-line. Let me know if that helps..

Now, I try to install NetBSD for Jetson TX1 development board.

I check some web pages including NetBSD/evbarm on NVIDIA Tegra https://wiki.netbsd.org/ports/evbarm/tegra/ ,
but there aren’t detail infomation how to install u-boot for TX1

I try to install pkgsrc/sysutils/u-boot-jetson-tx1, but I can’t boot TX1 succesfully.

I try command like below with recovery mode :
	$ sudo ./flash.sh -L u-boot-dtb.bin jetson-tx1 mmcblk0p1
This result, I see this error message in boot sequence.

Does anyone know how to install u-boot for TX1?

Thanks in advance.

Images at http://www.invisible.ca/arm/ is great!!

TX1 with original bootloader can boot kernel, but stop with this error message
 [   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

Does this mean that I can boot TX1 original bootloader with correct extlinux.conf or boot.scr?

This is my trial but in Japanese only
