Unable to programme my ESP32 - What am I doing wrong

[ioncoder]

I am now on my third PCB and am not able to connect to my ESP32. I have attached my schematic, PCB and the ESP32-D pin out, please could someone tell me if there is anything wrong with my wiring. I am quite new to electronics and this is starting to get quite frustrating. I tried originally with a dev board and everything worked, but building my own PCB is proving frustrating. I have checked the continuity on my pcb tracks that is fine.

I am powering the PCB from batteries (3 1.2V rechargeable AA's) and sharing GND with my programmer (Which works well with other DEV boards).




and here is my PCB



Here is the ESP32-D pinout



Thank you.

From the blurb I saw on your post I was keen to help, but as mentioned above - the pictures aren't visible.
