I have an Xiaomi Mijia 2018 (SXJ02ZM); that's a T20 device. I dumped the firmware using a CH431A programmer. Now wanted to try flashing OpenIPC, by writing a firmware directly on the flash memory.
Basic question perhaps but I need some pointers: how do I merge u-boot, the u-boot uImage, and the OpenIPC rootfs into 1 image, which I can then flash with the CH431A programmer?

The camera I have with USB data lines connected is Wyze v3, which runs Linux. The one with RT-Thread has a Fullhan FH8830 and is a HikVision doorbell that only has two external wires for 48VAC doorbell transformer. I desoldered & backed up and have full uboot on the doorbell to restore (re @ru67yn41l: I have a cam i think it's like your with unusefull rttread on board the chip is a bk7251 from bekencorp it's like a china A9 cam and serial is connected to usb plug (used only to power it) the serial connection was originally cutout on the board so it needed just a tic of solder iron on tx and rx lines.
Is your camera like mine?)

Seems like Wyze have set the countdown timer in uboot to 0 seconds

I thought shorting across some of the test pads or reset button during boot might bring me to uboot prompt but no luck so far

There are too many test pads to try every combination

I’d try writing a simple python script which will send Ctl-C many times quicker than human can do

if you wish to boot it that way,you have to build own kernel and specify default cmdline there,that will point to some rootfs

Thank you! Is there an installation method based on sd card? or do I really need to open the case and get serial connection? (re @widgetii: got it, it’s based on HI3518EV300 SoC

i won't advise to flash anything without access to serial console. the risk to brick your device is too high. it could be anything, from unsupported wireless card to a glitchy flash chip.
