I am trying to upload a blank sketch and received this
can you give a link to the specific ESP-CAM?
which Tools>Board did you select? I use "AI Thinker ESP32-CAM"
which specific FTDI board did you use?
I tend to use a ESP32-CAM-MB micro USB programmer
Is there a voltage jumper on the FTDI, is it set correctly? Or just try it several times at each voltage.
I was doing some experiments with the same rig a couple days ago and the FTDI is most reliable while the MB boards which I have a dozen of are not only not reliable, some simply never work.
all my FT232RL USB TO TTL adapters have some means of selecting 3.3V/5V
I assume you have connected GPIO0 to GND
and tried pressing the RST button when the dots show during upload
I have a couple of the ESP32-CAM-MB with 2 buttons - both work OK
they are certainly many fake chips and modules around - recently a batch of fake regulators which had to be replaced on custom PCBs
