[D1 mini: hardware Issue]: No Upload possible when Sleep Jumper is connected! #19

Open hasenradball opened 3 years ago

hasenradball commented 3 years ago

Hi,

I found a small hardware bug. If you solder the sleep jumper on the D1 mini lite, an upload is not possible until the jumper is closed. If you place an 10k resistor between GPIO16 and the Jumper everything is fine!

Please consider this in the next hw update.

I'm just looking to implement deepsleep on my d1mini pro 2.0 - could you elaborate a little more on the issues you encountered/the fix with the resistor?

MTIA!

Hi the issue is very simple. If you have flashed you ESP and everything is working fine AND you have closed the jumper the ESP will wake up no problem. BUT if you have closed the jumper and will flash again the ESP the flashing will not work fine because the RST has a DIRECT connection to GPIO16. And during flash the RST I think is triggered by the RTS signal of the flasher.

So if you are able to flash you WEMOS with closed jumper I think everything is fine, else connect a 10 K resistor between GPIO16 and RESET.

Also you could use my small dev board for the wemos...
