I'm trying to upload a new firmware on the unit roller connecting a ST_Link v2 to the SPI connector with STM32CubeProgrammer.
Roller SPI ---------------- ST_LinkV2
V --------------------- 3.3
G -------------------- GND
C ------------------ SWCLOCK
D ------------------ SWDIO
O ------------------- NC
when the firmware si uploaded the unit roller works (display right boot image and information, led is on, button and encoder works and menu works too), but if I disconnect the SPI cable and I power the unit from grove or dc in 6/16v, the unit doesn't work(black display, led off, etc).
this is the .hex firmware used.
and this is the cube log:

this is the log of OB:

}
If I power the unit from grove or DC in, I have 3.3v on SPI (V,G).
I tried to merge and burn a bootloader.hex too but no joy.
after uploading the firmware if I connect the grove cable of an atom lite running a i2c scanner code, I can see 0x64 on serial monitor. I can also disconnect the SPI cable and the roller still works until a power cycle.
ideas??
tnks a lot!!
