November 18, 20223 yr Author 17 minutes ago, mihaigsm2003 said: try write, maybe settings error or MCU faulty When I select the chip there are several GD32F105 like this: GD32F105xx where can I find the last letters?

November 18, 20223 yr When you connect the interface to the display for programming, does any LED light up? that is, you have 3.3 volts, at the same time, did you make the settings correctly for that type of microcontroller? Maybe you need to supply voltage to the board, if I remember correctly I also used RST connected to the MCU. Jlink is a little more complex, and I have worked with it a little. This is pinout (this board have STM32F107, but same pinout)

November 18, 20223 yr Connect VTref to 3,3V on board or to Vcc on interface, Check if VCC on interface is 3,3V Use power from interface becouse reset MCU when do job Use SWDIO and SWCLK also maybe need reset pin to MCU (see datasheet for GD32F105)

But the display still does not turn on
November 18, 20223 yr i add new file, try, also, check all fuse from board mrked with yelow. Maybe gd32 use other bootloader 25.05_GD32F305VET6.hex 02.70 display ok pyl.hex

November 18, 20223 yr Firmware is for offgrid, inverter work? get power? Now can update with official good firmware via serial cable, don't push DSP button Edited November 18, 20223 yr by mihaigsm2003

DSP firmware, Inverter can work witout display If u try update DSP firmware this is big problem if invertor not get power on load What model of inverter 8k? Try this firmware for display Remote Panel_Reflash_MCU(112.19)_MAX.rar

November 18, 20223 yr this i have, maibe not last... Don't use inverter witout battery! Can destroy hardware good luck!
