Hello All,
I have received a PCB which is used in a battery pack that i am working on.
Unfortunately the CM does not communicate any more and the last he told me was that they did not flash the devices.
The PCB has basic functionalities like displaying battery power via LED lighting, charging battery and discharging and couple of WIFI, BT modules that are connected to the MCU - STM32G0B1CEU6N microcontroller (MCU)
Upon looking at the schematic - the PCB has SWD and JTAG.
I tried connecting the PCB via ST-LINK-V2 to STM32Programmer but the software does not detect at all.
I checked the SWDIO, SWCLK, NRST, GND wiring (made sure they are all correct by checking continuity) gave VDD power input to the 3.3 V input on ST-LINK-V2 but no luck.
What i would like to understand is that could this be an RDP issue? where RDP level 1 is blocked and i need to connect via JTAG to enter the MCU and be able to flash it?
Thanks for the help..
