Thanks. My board has KMQN10006B-B318 eMCP chip. Also, I experimented with different usbplug loader parts - board boots with v2.53 (which is in this loader) and hangs with v2.56.

try to erase flash w/o boot downloading. also if you have box with KMQN10006B-B318 - it'll fail to boot with current multitool/armbian (their loader hangs on this board with this RAM/ROM eMCP chip). I reported this in rk322x thread I think updated images will be available soon.

It doesn't work for me on same board, but shorting any data lines to each other pushed chip to mask rom on boot. I have 1.5G/8G version, and it doesn't boot armbian or multitool from sd/emmc - it just hangs on boot with no output to console (1500000 and 115200 speed)

you don't need loader on EMMC to boot from SD. and it seems like you have booted loader, not maskrom mode

Godziller, I have similar board and had bricked it. I just shorted some pins on resistor pack (51R x4, they are on D0..D7 lines) and it falls to mask ROM. Main trouble in similar boards is 1.5GB RAM eMCP pack which requires special bootloader (DDR init 1.10 doesn't support 1.5G, it detects 2G and hangs). I extracted and re-assembled loader from firmware, it has DDR init code v1.11 and usbplug v2.53 (v2.56 halts system boot).

hi all. does anybody have rk322x loader with ddr init module v1.11? I have board with 1.5GB RAM (eMCP 1.5/8G), loader with 1.10 saw it as 2GB and fails on load. or is there a simple way to extract it from stored fw dump? UPD: I extracted loader from firmware update, it's attached here:
