Yay! I made the same change to the U-Boot .dts also, but U-Boot shouldn't ever write to the FS, so I'm not sure that it's really needed.

I will say, lowering the eMMC frequency in the device tree from 200Mhz to 150Mhz (Option #2 from https://forum.odroid.com/viewtopic.php?f=135&t=22717&sid=ded7347a42187439391dcab01e3e3245&start=700#p209636 ) seems to have fixed the corruption issue for me!

Igor, Ah, thanks for the CREATE_PATCHES tip. I was trying to cheat and not rebuild the whole thing if I didn't need to, and I wasn't sure about patching the code. So I'll look into that! Basically the problem is that the default u-boot is configured to respond to both UARTs, and I have a GPS unit spewing NMEA output attached to the UART on the GPIO pins. u-boot receives the output and aborts autoboot, and so the unit never boots. Easy config change, but when the new binary doesn't work.. Thanks again!

Since I was experiencing the eMMC corruption issue with u-boot 2017.11 & mainline, I'm back to the Armbian Xenial (legacy kernel) image. Everything works great, except I need to tweak the u-boot config slightly. To start, I'm just building the defconfig and then going from there. So for what I'm doing on my Ubuntu Bionic devel VM: $ git clone --single-brach --branch odroidc2-v2015.01 --depth 1 https://github.com/hardkernel/u-boot.git $ <apply the 2 patches from https://github.com/armbian/build/tree/master/patch/u-boot/u-boot-odroidc2 > $ export CROSS_COMPILE=aarch64-linux-gnu- $ make odroidc2_defconfig && make $ sudo cp sd_fuse/{bl1.bin.hardkernel,u-boot.bin} /usr/lib/linux-u-boot-odroidc2_5.37.180120_arm64 $ sudo -i # source /usr/lib/linux-u-boot-odroidc2_5.37.180120_arm64/platform_install.sh # write_uboot_platform /usr/lib/linux-u-boot-odroidc2_5.37.180120_arm64 /dev/mmcblk0 That all works, except when I reboot, U-boot goes into a tight loop about not being able to load a valid bmp and then unrecognized file format. I'll get the exact text in the morning after I reload the old files onto the eMMC again. Any pointers on what I'm doing wrong? Thanks!
