@ebin-dev confirmed the new image works great. Thanks again!

@ebin-dev, @Rainbaby Many thanks. I will try to flash the new image tonight and update this thread on how it goes.

After further experimentation, I am able to flash the flash-image-ddr4-1g-2cs-1000_800.bin image and everything is back to normal, though I am restricted to 1GiB of RAM. Interesting since the official 2g image from espressobin.net works fine

I just got a new espressobin v7 with 2gb of ram. Output from working u-boot: U-Boot 2017.03-armada-17.10.2-g255b9cc (Nov 07 2018 - 09:48:30 +0800) Model: Marvell Armada 3720 Community Board ESPRESSOBin CPU @ 1000 [MHz] L2 @ 800 [MHz] TClock @ 200 [MHz] DDR @ 800 [MHz] DRAM: 2 GiB U-Boot DT blob at : 000000007f7161b8 Comphy-0: USB3 5 Gbps Comphy-1: PEX0 2.5 Gbps Comphy-2: SATA0 6 Gbps ...

So everything seems to go ok. From here, I reset the board and I get nothing at all. No serial console, nothing. I need to go into uart just to get any kind of a sign that the board is still alive. From uart I can recover using the following image from http://espressobin.net/tech-spec/ (U-Boot 2017.03-armada-17.10): espressobin-bootloader-cpu-1000-ddr4-2cs-2g-atf-g39a62a1-uboot-g255b9cc-20181107-REL.bin which brings me back to the initial state at the start of this post. Any ideas why flashing the latest u-boot image from armbian seems to completely bricks my board? Thanks!
