ESP32-c3-mini reading flash memory from soldered chip

[Vaidas82]

Hello esp32 experts!

Have the following problem:
Have two same devices. One defect, one working. Defect one blinks an led without response to anything and is not recognized. Installing bad motherboard in good device doesn't change anything so my main suspect is motherboard/software as all components on motherboard seems fine, no shorts.
Motherboard has esp32-c3-mini comunicating with stm32 that turns on different things. Connection points for both chips exist on the motherboard. Was able to read out stm32, rewrited the chip with flash from good chip with no result. Writed original flash content back in to it. Now my main suspect is the esp32. Can someone suggest what interface hardware I need to communicate with esp32 chip? To what pins do I need to solder wires for the communication? Picture of available motherboard pins with written names around the esp32 chip attached.. (soldered wires for the communication with stm32)

We cannot tell for sure as we don't have the PCB artwork for your PCB, but I'd suggest connecting an USB-serial converter to J2. Try gnd/ble_rx/ble_tx first.
