GD32f130 ?
Maybe you need to install a new binary because removing read protection did erase the original firmware ?
It needs a working firmware to keep the power on after a short press on the on button, which gives 3.3V to the mcu so the code can start.

i did complete chip erase and installed a new bin successfully(had to hold the power button ), but still wont turn on (vbat only shows 3.3v while holding power). i think the power latch circuit is somewhere on the board ?

this guy: 2.1.6 (todo)

[RoboDurden]

so you did compile your 2.1.6 dummy firmware, yes ?
in config_2-1-6.h i read

// todo: BUTTON not working but hiliving is sure to have traced the pin correctly with the help of ailife

So in the bginning you might need to bridge the on-button to keep the board powered.

If the motors are then spinning forward and backwards with the RemoteDummy, you can already be happy..

Good night from Germany.

Watch my autodetect youtube tutorial. You could retry the autodetect to get the board alife..
