If you don't have any resistor or diode, the deepSleep wakeup will not work.
You should use RES + GPIO0 to enter in upload mode.
If this doesn't work, you must have a wiring problem.
Do you have GPIO2/GPIO0 pulled-up while GPIO15 pulled-down ?
Do you have CG_PD pulled-up ?

Hi Martin, YES! That actually worked. Connected RST and A0 and I could upload my code again.

Thank you sooo much!

Okay I dont get it working with the Flash button, but the RST to A0 connection was not why it worked.
I have the 4.3" E-Ink display connected and only when I disconnect it from the board I can flash it.
Does not really make sense for me. Its only connected to D2, 3V, GND, RX and TX. Very weird.

- Sun Mar 19, 2017 8:25 am #63936 If the E-Ink display is connected at TX/RX at the same time you try to upload, maybe it is responding some thing from the upload command which then corrupt the handshaking.
In this case, you don't have much choice to disconnect it on every upload.
