Re: Allwinner H3 support added to -current

Hi Yuqing --

Thank you for the dmesg. Very excited to see other boards working with no changes.

I've committed support for another way to boot the installer, but haven't tested the entire process yet. Please try it and let me know how it goes.

If you do a full release build, there should be a 'ramdisk.fs' somewhere in the obj directory (I think). This is normally used as an embedded ramdisk image in the *_INSTALL kernels.

Instead, add a legacy U-Boot header to the ramdisk.fs file (make sure your mkubootimage is up to date, I checked in a fix for this last night):

 $ mkubootimage -A arm -C none -O linux -T ramdisk -a 0 -n "NetBSD/sunxi ramdisk" ramdisk.fs ramdisk.ub

Copy 'ramdisk.ub' along with the 'netbsd.ub' from the SUNXI kernel to your SD card. Try booting like this:

 setenv kernel netbsd.ub
 setenv ramdisk ramdisk.ub
 fatload mmc 0:1 ${kernel_addr_r} ${kernel}
 fatload mmc 0:1 ${fdt_addr_r} ${fdtfile}
 fdt addr ${fdt_addr_r}
 fatload mmc 0:1 ${ramdisk_addr_r} ${ramdisk}
 bootm ${kernel_addr_r} ${ramdisk_addr_r} ${fdt_addr_r}

If all goes well, it should use the ramdisk.ub file for the root fs and start the installer.

If this works, I'll remove the SUNXI_INSTALL kernel and include a ramdisk.fs/ramdisk.ub in the release build instead.

Hi Jared:

I attached the dmesg of booting Orange Pi PC Plus.

I will try the flowing method as you mentioned to boot an install.ub.
Thank you again!

Yours Yuqing.

Not sure yet how to boot with "go". I tried converting the .bin to a Legacy U-Boot image like this:

$ mkubootimage -A arm -C none -O linux -T kernel -a 40008000 -n "NetBSD/sunxi install" install.bin install.ub

Oops, there's a typo in that command -- the -a value needs to be specified in hex, so the correct command would be:

$ mkubootimage -A arm -C none -O linux -T kernel -a 0x40008000 -n "NetBSD/sunxi install" install.bin install.ub

Still need to increase CONFIG_SYS_BOOTM_LEN though.
