no prompt after uploading #22

Closed TecDroiD closed 3 years ago

After i didn't manage to compile µpy on my own I uploaded your firmware to my esp32cam which worked pretty fine but sadly I cannot get a python prompt after that. tried picocom using 460800, 115200 and 19200 baud.. What can be wrong here?

seems that this isn't a micropython issue. i use esp32 cam board on top of the ESP32-CAM-MB which is basically a ch340 usb driver. haven't yet found a schematic of it but somehow it prevents loading the console. So using a normal usb-ttl cable, i finally got the prompt :-)

Hint: seems that ch340g needs some explicit settings. $ picocom -b 115200 /dev/ttyUSB0 --lower-dtr --lower-rts worked for me.
