I recently bought an esp32 cam module on aliexpress and have a dedicated esp32 cam mb programmer with no problem programming the boards from batland but with this one there is a proplem on the serial port it sends the phrase app task running but the board does not connect it cannot be programmed...

To program the ESP32-Cam, the IO0 pin must additionally be bridged to GND. Link .

More specifically, IO0 must be connected to ground during boot. If you turn on the ESP and it's already walking, then bridging IO0 to ground won't do anything. I usually: - I either bridge IO0 to ground before connecting it to the power supply - or I bridge IO0 to GND and then perform a reset by short-circuiting RESET to GND for a while Added after 41 : By the way, here's the footage: ESP32-Cam, how to start and operate the camera with ESP32 in PlatformIO? .

during programming, connect a jumper to IO0 GND

ESP32-Cam, how to start and operate the camera with ESP32 in PlatformIO? .

I am creating multiplatform open source firmware (Tasmota replacement), right now supporting BK7231T, BK7231N, XR809, BL602, W800, W600, LN882H and soon supporting RTL and W701:
