Firmware does not find BQ27546?

[ConiKost]

Since I placed an order on JLCPCB for something else, I also did order two assembled Blinkekatze PCBs (with BOM as intended) for some fun.

Can I run a test without connected switch board? My switchboard seems to have only five wires, not six.

It looks like, that flashing the firmware, it does not find the BQ27546? Could be those PCBs or parts faulty? I have not enabled flashing ti battery gauge. Or could be no firmware flashed at all on the BQ27546, so it's not detected? Is there any cheaper alternative to EV2400, if this could be the case?

[ConiKost]

I did a small test and disabled step by step ESP_ERROR_CHECK. After everything disable, the ESP-C3 boots to shell. But it looks like, that nothing is on the i2c bus? So both faulty produced and assembled PCB by JLCPCB?

[ConiKost]

@TobleMiner any idea on that?
