NetBSD armv7 9.0 NetBSD 9.0 (GENERIC) #2: Mon Mar 23 15:25:33 EDT 2020  root@armv7:/usr/obj/sys/arch/evbarm/compile/GENERIC evbarm
>Description:
Since the final release of NetBSD 9.0, I have not been able to boot from it on my Odroid-HC1.  However, I can boot from RC1, and have been able to compile the RC2 kernel and boot from it.

I have tried narrowing down where the problem lies and think that I've found it.  In particular, if I substitute /usr/src/sys/arch/evbarm/fdt/fdt_machdep.c from the RC2 source files to the final release source files and recompile the kernel, the system will boot.  

I have not yet extensively tested this modified release kernel, but will continue to do so.  However, I thought that you should know about this ASAP.

Be well.  Take care of yourself in this difficult time.

any time I try to boot from the final release 9.0 kernel

 Thanks for this.

 Please pardon this noobie response.  I wasn't able to try the link that you sent me because I'm unclear about how to load the software onto the SD card.  Documentation is simply lacking, or not findable.

 However, I was able to copy the current image (NetBSD-evbarm-earmv7hf-202003232120Z-odroid-xu3.img.gz) that I could flash to the SD card from https://www.armbsd.org/arm/.  This is to confirm that it boots properly on my Odroid-HC1.

 I have not tried anything else so far.

 The Odroid-XU4 build on

 	http://www.invisible.ca/arm/

 should work I think

 Nick,

 This is to let you know that, at least as the Odroid-HC1 is concerned, the contents of the //www.armbsd.org/arm/ and //www.invisible.ca/arm/ are identical.

 I don't know if I should post this in a new bug report, but the NetBSD-evbarm-earmv7hf-202003240450Z-odroid-xu3.img.gz release only finds 5 of the 8 CPU's of the HC1.  But, I can build kernels on it.  Unfortunately, the latest stable kernel (downloaded by CVS) also only finds 5 of the 8 CPU's.

 I'm trying to get ZFS working, so right now I'm not interested in using a current release.

 Thanks.


 John
